Use this when a user asks what traded goods are worth at the border, per kilogram, as declared to customs: for example what a country pays per kg to import wheat, diesel, cheese or timber, or earns per kg exporting whisky or steel, in the United Kingdom (country GB), optionally from or to one partner country. Returns the customs value divided by the net weight (a value-weighted average per kg in the reporting country's currency), a range between the 10th and 90th percentile of the individual customs lines weighted by weight, the months it covers, the biggest partner countries and the official source and licence. This is a customs unit value (price_type official_statistic) built from declared trade values and weights, not a shelf price, not a wholesale quote and not a receipt, so there is no sample size. How fresh: monthly: HMRC publishes each month's trade statistics about six weeks after the month ends; our figures are read live and each answer states its months. Do not use for what a shopper pays in a shop, for a single contract or shipment, for futures or spot quotes, for services, or for countries that are not listed.

Use this when a user asks what home internet (fixed broadband at a given speed, with or without phone and TV) or a mobile data plan costs per month in the EU, or how that compares between countries. Returns the official figure for a standard offer in the latest year published, the previous year and the change, and the same country's other offers, with the official source and licence. It is the cheapest posted offer of the largest operators, not what customers actually paid, and not a range built from sales: the range fields are null and there is no sample size. How fresh: annual figures with a lag of about two years (newest year 2024, dataset updated May 2026); each answer states its reference year. Do not use for a quote from one provider, for business lines, or for countries that are not listed.

Use this when a user asks what people actually paid for the right to own or buy a car (an entitlement or quota certificate, a sale or an auction result) in Singapore car ownership rights (COE) (country SG). Returns the median winning price, a typical range (10th–90th percentile), the number of bidding rounds or sales, the period covered, a confidence label, and the official source and licence. Do not use for asking prices, dealer listings, or other countries.

Use this when a user asks what childcare costs parents: the price of a nursery, daycare, childminder or after-school place for a baby, toddler, preschool or school-age child in a county, region, state or city, or how childcare prices compare, in England (country GB), Ireland (country IE), Norway (country NO) or the United States (country US). These are official surveys and statistics of the fees providers charge parents (or what households report paying), not adverts or listings, and they are before public subsidies or funded hours unless the answer says otherwise. Each answer is an official average or median (price_type official_statistic): the range fields are null, and there is a sample size only where the publisher gives one. Every answer states its unit (for example US dollars per week, or pounds per hour), the year it describes, a confidence label, and the official source and licence. How fresh: England: calendar year 2025 (survey fieldwork May to July 2025, published 11 December 2025; next release December 2026); Ireland: 2016 only (CSO has not repeated the table); regional, not county; ten years old; Norway: annual (January figures); the 2026 figures were published on 30 April 2026; the United States: county prices for 2022 (the latest year the Department of Labor has published; the database lags by several years). Some of this data is several years old: always read the period in the answer. Do not use for the cost of a specific nursery, advertised fees or waiting-list prices, the value of government subsidies, tuition for schools or universities, babysitting or nanny wages, or other countries.

Use this when a user asks what shops, offices, workshops, warehouses or other commercial premises actually sold for, or what a plot of non-farm land (a building plot) sold for, per square metre, in a town or postcode, in France (country FR) or Taiwan (country TW). Returns the median price per square metre, a typical range (10th–90th percentile), the number of sales, the period covered, a confidence label, and the official source and licence, from government sale records (prices paid, not asking prices). How fresh: France: twice a year, with a delay of several months; Taiwan: every 10 days. A sale appears one to two months after the deal; answers cover whole calendar months ending at least 30 days before the newest deal. Do not use for homes, farmland, rents, asking prices or listings, the value of one particular building, or other countries.

Use this when a user asks what it costs to build a home or other building per square metre in Brazil (country BR), how much of that is materials and how much is labour, or how states or regions compare. Returns the official average cost per square metre for the latest month published, split into materials and labour, with the previous month, the official source and licence. This is a published survey average of unit costs (price_type official_statistic), not a range built from invoices or sales, so the range fields are null and there is no sample size. How fresh: monthly; the latest month on 16 Oct 2026 was September 2026. Do not use for the price of a finished home, for a builder's quote, for renovation work, or for countries that are not listed.

Use this when a user asks what governments, councils, hospitals or other public buyers actually paid for something (laptops, school meals, road resurfacing, office cleaning, electricity, ambulances, waste collection and similar purchases) in Australia (federal contracts, AusTender), Canada (federal contracts, CanadaBuys), Colombia (public contracts, SECOP II), EU and EEA states (TED), France (public contracts, DECP), the United Kingdom (Contracts Finder), New Zealand (GETS), Singapore (GeBIZ), the United States (federal contracts) or South Africa (public contracts, eTenders). Returns, from official contract award notices, the median awarded value per contract, a typical range (10th–90th percentile), the number of awards, the period covered, a confidence label, and the official source and licence. Important: the figures are TOTAL values per contract (lot), not unit prices, unless the answer states a unit price (only when the notices give a quantity and unit). Nothing is returned for fewer than 5 awards, and individual suppliers are never named. How fresh: Australia (federal contracts, AusTender) and the United Kingdom (Contracts Finder): continuous: buyers publish award notices after a contract is awarded; Canada (federal contracts, CanadaBuys): daily: CanadaBuys refreshes the award notice files every day and our copy is collected once a day; Colombia (public contracts, SECOP II): daily: Colombia Compra Eficiente refreshes the open dataset about daily and our copy is collected once a day; EU and EEA states (TED): daily on working days: notices appear on TED within days of the buyer sending them; France (public contracts, DECP): daily: the consolidated monthly files are refreshed about daily and our copy is collected once a day; New Zealand (GETS): quarterly; awards up to the end of the last quarter; Singapore (GeBIZ): yearly; the United States (federal contracts): daily: agencies report contract actions within days and USAspending refreshes nightly; South Africa (pub

Use this when a user asks what households pay for electricity or natural gas per kWh in Brazil, Switzerland, the EU, Norway and Iceland, Great Britain, the Netherlands, New Zealand, Sweden, Singapore, Taiwan or the United States, how that compares with another country, or how it changed since the previous period. Returns the official average price per kWh for a standard household consumption band, for the latest period published, with the same band excluding VAT and excluding all taxes, every band, the previous period and the change, and the official source and licence. This is a published average (price_type official_statistic), not a range built from sales, so the range fields are null and there is no sample size. How fresh: Brazil: updated whenever ANEEL homologates a tariff adjustment (each distributor adjusts once a year); each answer states the validity period of the tariff; Switzerland: yearly: ElCom publishes next year's tariffs in autumn; each answer states the tariff year; the EU, Norway and Iceland: updated twice a year (half-yearly figures); each answer states its reference period, and the newest half-year Eurostat holds for the country is returned; Great Britain: quarterly (the cap is reset on 1 January, 1 April, 1 July and 1 October); each answer states the quarter it is for; the Netherlands: half-yearly (new figures end of March and end of September; the last two half-years are provisional); each answer states its reference half-year; New Zealand: monthly file; the newest month is about four to five months behind today. Each answer states its month.; Sweden: half-yearly (new half-year about three months after it ends); each answer states its reference half-year; Singapore: annual: the newest full calendar year (2025 was published in 2025-10); each answer states the year; Taiwan: updated when Taipower changes its tariff; each answer states the date the table took effect; the United States: monthly: EIA adds a month to each table about two months after

Use this when a user asks what farmers received, per month, for a crop or animal product (wheat, barley, oats, canola, soybeans, corn, potatoes, cattle, hogs, lambs, chickens, turkeys, milk, eggs) in a region of Canada, or how that price compares with the month before or a year earlier. Returns the newest monthly price the statistics office publishes for the product and region, in the unit the office uses (per tonne, per hundredweight, per dozen, per kilolitre), the month it applies to, the change on the previous month and a year earlier, the last 12 months, the same product in other regions, and the official source and licence. This is a published monthly average price received by farmers (price_type official_statistic), not a range built from sales, so the range fields are null and there is no sample size. How fresh: monthly, not live: Statistics Canada publishes each month's averages about six weeks after the month ends (August 2026 was released on 9 October 2026), and every answer states its reference month. Always read the month in the answer. Do not use for supermarket or shop prices, for wholesale market quotes, for the price of a particular farm, field or animal, for farmland, for fuel or energy, for futures prices, or for EU member states.

Use this when a user asks what farmers or wholesalers get for a food commodity (wheat, barley, maize, beef, pigs, lamb, chicken, eggs, milk, butter and other dairy products, olive oil, fruit and vegetables) in EU member states, how that price compares with last week, last month or a year ago, or how high it is against the last 12 months. Returns the latest official price for the country and product, per tonne or per 100 kg and per kg, for the week (milk: month) it applies to, the stage of the supply chain it is quoted at (farm gate, ex-silo, carcass, ex-packaging station), the change from the previous period and from a year earlier, the last 12 months, the other series the portal holds, and the official source and licence. This is a published price (price_type official_statistic), not a range built from trades, so the range fields are null and there is no sample size. How fresh: weekly for most products (raw milk monthly), updated as Member States report, usually within days (raw milk about two weeks after the month ends). Each answer states its week or month and flags quotes that are older than usual (fruit and vegetables are only quoted in season). Always read the period in the answer: an old quote is flagged and given lower confidence. Do not use for supermarket or shop prices, for the price of a particular farm, field, animal or meal, for farmland, for fuel or energy, for futures or stock-market prices, or for other countries.

Use this when a user asks what people actually pay for a flight between two cities or airports (for example JFK to LAX, or Chicago to Miami), or what the average airfare out of a city is, in Australia (domestic routes) (country AU) or the United States (domestic flights within the contiguous 48 states) (country US). Returns the official average fare per passenger each way, in the currency the answer states, for the latest quarter published, with (where the source publishes them) the passengers per day behind it, the share of the largest carrier, the change on a year earlier and the last few quarters, plus the official source and licence. This is a published quarterly average of fares paid (price_type official_statistic), not a range built from tickets, so the range fields are null and there is no sample size; how fresh: Australia (domestic routes): monthly; the newest month is usually the one just ended; the United States (domestic flights within the contiguous 48 states): quarterly, published about five to six months after the quarter ends (the first quarter of 2026 was published in September 2026); every answer states its quarter. Do not use for today's fare, a specific date, airline or cabin, a booking or price alert, international flights, routes outside the places named above, hotels, or other countries.

Returns the median and typical range of pump prices across stations in the area, the three cheapest stations, and the official source and licence. How fresh: Queensland: monthly file, published about a month after the month ends (the newest data is usually 5 to 8 weeks old); Brazil: ANP publishes the survey as one file per month, so the newest survey week is usually one to four weeks old. Our copy is refreshed daily, and every answer states the survey week it describes; Ontario: weekly (Mondays, before the end of the business day; the next working day after a holiday); Canada: monthly, not live: Statistics Canada publishes each month's averages about two weeks after the month ends (August 2026 was released on 14 September 2026), and every answer states its reference month; Spain: several times a day; the EU (national averages): weekly: Monday prices, published that week; France: about every 10 minutes; the United Kingdom (national averages): weekly: one national figure each week, usually available the same week; Italy: daily (prices at 08:00 of the extraction day); Mexico: the feeds are current prices reported by the stations and carry no timestamps; our copy is taken once a day and every answer shows the day of that copy; Malaysia: weekly, on Thursdays; the Netherlands: weekly publication of daily averages: new days appear each Thursday, up to the Monday of that week; every answer states the day it is for; Norway: monthly; the newest month is normally published in the first weeks of the next month (table updated 21 October 2026 with September 2026); every answer states the month it is for; New Zealand: weekly (Fridays

Use this when a user asks what a home upgrade costs in England and Wales (heat pumps) (country GB), Great Britain (country GB) or Ireland (country IE): a heat pump, solar panels (solar PV), loft/attic or wall insulation, or new windows. Returns an official statistic: the cost that installers or owners declared when a grant or tax claim was made (a median or average the publisher states for a period), with the period, the publisher's own wording of what the figure includes, the official source and licence. These are declared installed costs at grant or claim, not receipts, not quotes and not what one home paid; price_type is official_statistic, so the range fields can be null and the sample size is given only where the publisher states it. Each source covers only some measures: where a measure is not published the answer says so (status no_matches) instead of guessing. How fresh: England and Wales (heat pumps): monthly (the cost tables are updated each quarter, in January, April, July and October; the latest quarter ends about three months earlier); Great Britain: yearly (published each May for the financial year just ended; April to March); Ireland: irregular; the local-authority table currently ends with 2018/19. Some countries publish only a general renovation figure that is not split by type of work (the country notes say so). Do not use for a quote on a particular home, for installer prices or offers, for running costs or savings, or for other countries.

Use this when a user asks what a hotel room costs per night, on average, in a country, region, province or city in Spain (country ES), Finland (country FI), Hong Kong (country HK) or Norway (country NO), or how hotel prices changed on a year earlier. Returns the official average daily rate: the average price actually charged per occupied hotel room per night, published monthly by the national statistics office from its hotel survey, with the month, the change on the same month a year earlier where published, the official source and licence. This is a published average over all hotels in the area, not a range of individual bookings and not a quote for a date, so the range fields are null and there is no sample size. How fresh: Spain: monthly, published about six weeks after the month ends; every answer states its month. Monthly history back to 2008; Finland and Norway: monthly, published about five weeks after the month ends; every answer states its month; Hong Kong: monthly, 2 to 3 months behind.

Use this when a user asks what insurance actually costs the people who hold it, for example what homeowners pay per year for flood insurance in a ZIP code or state, in the United States (federal flood insurance) (country US). Returns the median yearly charge with the typical range (10th to 90th percentile) across real policies, the number of policies behind it, the period, a confidence label, and the official source and licence. Only aggregates are returned, never one policy, and never fewer than 5 policies. Read the method in the answer: some premiums are set partly by public rules, so they are real charges but not a free-market quote. How fresh: updated about monthly (data as of 2026-09-08 when checked); every answer states the period it covers. Do not use for a personal quote, for insurance that is not covered by a source here, for the value or replacement cost of a home, or for other countries.

Use this when a user asks what agricultural land (farmland, arable land or grassland) sells for, or what it costs to rent, per hectare in EU member states and Norway, in a particular region of such a country, or how it changed since the year before. Returns the official average price per hectare (or the average rent per hectare for one year) for the latest year published, in the currency the answer states (euro and national currency where the source gives both), for the chosen land type (arable, permanent grassland and others), the previous year and change, the history, the other land types, the regions that exist, and the official source and licence. This is a published average (price_type official_statistic), not a range built from sales, so the range fields are null and there is no sample size. How fresh: annual. Eurostat publishes land data with a lag of about two years (on 2026-10-14 the newest year is 2024) and some countries are further behind; each answer states its reference year and flags old figures. Always read the reference year in the answer: the data are about two years behind and some countries are much older. Do not use for the value of a particular field or farm, for house or building land or commercial property, for listings or asking prices, or for other countries.

Use this when a user asks what a medical service or hospital stay costs, or what was actually paid for it, for example an office visit, an MRI, a colonoscopy, physical therapy, a knee replacement or a pneumonia stay, in Singapore (hospital bills for medical conditions) (country SG) or the United States (what Medicare paid doctors and hospitals) (country US). Returns the official average amount the public health insurer allowed per service (doctors' services, in an office or a facility) or paid per hospital stay (by hospital-stay group), nationally or for one state where the source publishes it, with the number of services or discharges behind it, the share the insurer itself paid, the national average for comparison and the data year, plus the official source and licence. These are public-insurance rates (price_type official_statistic): what the insurer allowed or paid, NOT private-insurance negotiated prices or cash prices, which are usually higher, and not a quote. A published average, so the range fields are null. Facility figures are the doctor's fee only; the hospital's or surgery centre's fee is separate. How fresh: Singapore (hospital bills for medical conditions): annual benchmark file (data year 2023, file last updated 15 May 2026); every answer states its data year; the United States (what Medicare paid doctors and hospitals): annual: one calendar year at a time (the 2024 data year was released in 2026); every answer states its data year. Do not use for a quote or what a specific hospital or doctor charges, private-insurance or out-of-pocket costs, drug or prescription prices, dental or vision plans, or other countries.

Use this when a user asks what a medicine costs in a pharmacy, or how much of the price the health insurance reimburses, in Spain (country ES), France (country FR), England (NHS) (country GB), Italy (country IT), Japan (country JP), New Zealand (country NZ) or the United States (country US). Returns the median and typical range (10th–90th percentile) of the legally fixed price per box across all pack sizes and strengths sold under that medicine name, the number of packs, the period, a confidence label, and the official source and licence. These are regulated (posted) prices, not market transactions, and only for reimbursable medicines. Do not use for over-the-counter products with free prices or for other countries.

Use this when a user asks how expensive a country is compared with an international average, for everyday spending such as food, housing, transport, health, clothing or restaurants, for example 'is food dearer here than in a neighbouring country', 'how much more expensive is a country than the average' or what a dollar buys in local currency (purchasing power parity), in 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country AU), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country AT), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country BE), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country CA), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country CL), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country CO), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country CR), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country CZ), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country DK), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country EE), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country FI), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country FR), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country DE), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balkan states) (country GR), 47 countries (the 38 OECD members plus Bulgaria, Cyprus, Malta, Romania and some Balka

Use this when a user asks what farmers received at the farm gate, per year, for a crop or animal product (wheat, maize, rice, soybeans, potatoes, tomatoes, apples, bananas, beef, pork, chicken, eggs, milk, coffee, cotton and many more) in 9 countries from FAOSTAT (US, CA, BR, MX, AU, NZ, SG, JP, KR), or how that annual price changed from the year before. Returns the newest annual producer price for the country and product, per tonne in the country's own currency (and in US dollars where available) and per kg, the year it applies to, the change on the previous year, whether the source marks the figure as estimated, related products, and the official source and licence. This is a published official statistic (price_type official_statistic), not a range built from sales, so the range fields are null and there is no sample size. How fresh: annual. FAO refreshes the file a few times a year and the newest year is usually one to two years behind today; our copy is refreshed daily and each answer states its reference year and whether FAO marks it as estimated. Always read the year in the answer: the newest annual figure is often one to two years old. Do not use for weekly or daily market quotes, for supermarket or shop prices, for the price of a particular farm, field or animal, for farmland, for fuel or energy, or for futures prices.

Use this when a user asks what rent tenants actually pay or have agreed for a home in a town, area or postcode, how much it costs to rent a flat, house or room there, or how rents compare, in New South Wales, Australia (country AU), Queensland, Australia (country AU), Canada (country CA), Germany (country DE), Catalonia, Spain (country ES), Finland (country FI), France (country FR), England and Wales (country GB), Hong Kong (country HK), Ireland (country IE), Norway (country NO), New Zealand (country NZ), Portugal (country PT), Sweden (country SE), Singapore public housing (country SG) or Taiwan (country TW). These are rents actually agreed or paid, taken from official records and statistics: registered tenancies, rental bond lodgements, approved rentals, or official rent statistics built from administrative records of tenancies. Where the source holds individual rents the answer is a median with a typical range (10th–90th percentile) and the number of rents; where the source publishes an average or median (price_type official_statistic) the range fields are null and there is no sample size. Every answer states its unit (rent per month or per week, in the local currency), the period covered, a confidence label, and the official source and licence. How fresh: New South Wales, Australia: monthly; a month's lodgements are published in the first days of the next month; Queensland, Australia: quarterly; the RTA updates the workbook in April, July, October and January (the September quarter was published on 15 Oct 2026); Canada: annual: the October survey is released in the months after it (the October 2025 figures were released on 17 December 2025), and every answer states its survey month; Germany: static: the census date is 15 May 2022 (published 2024); the answer states that date and is not updated; Catalonia, Spain: quarterly; latest published quarter Q1 2026 (dataset updated 30 July 2026); Finland: quarterly; the newest quarter in the table on 22 Oct 2026 was 2026Q3

Use this when a user asks what used, surplus or seized goods (vehicles, heavy equipment, electronics, office furniture, tools and similar) went for at public auction in Canada (federal surplus), France (state auctions) or the United States (federal surplus). Returns the median final bid on sold lots, a typical range (10th–90th percentile), the number of lots, the period, and the source and licence. How fresh: Canada (federal surplus): half-yearly files; the newest sale in the latest file can be several months old; France (state auctions): yearly file: calendar 2024 (published 20 Feb 2026); the 2025 file is expected around Feb 2027; the United States (federal surplus): monthly file, covers the last six months of auctions. These are winning bid levels on lots marked sold (before any buyer premium, not confirmed receipts) for used goods, not retail prices. Nothing is returned for fewer than 5 lots, and no seller or lot is named. Do not use for new goods, shop prices or other countries.

Use this when a user asks what a university or college charges students per year (tuition or registration fees for a bachelor's or master's degree) in Canada (country CA), Europe (country BE), Europe (country BG), Europe (country CZ), Europe (country DK), Europe (country DE), Europe (country EE), Europe (country IE), Europe (country GR), Europe (country ES), Europe (country FR), Europe (country HR), Europe (country IT), Europe (country CY), Europe (country LV), Europe (country LT), Europe (country LU), Europe (country HU), Europe (country MT), Europe (country NL), Europe (country AT), Europe (country PL), Europe (country PT), Europe (country RO), Europe (country SI), Europe (country SK), Europe (country FI), Europe (country SE), Europe (country AL), Europe (country BA), Europe (country CH), Europe (country IS), Europe (country LI), Europe (country ME), Europe (country MK), Europe (country NO), Europe (country RS), Europe (country TR) or Taiwan (country TW), or how fees compare between countries or between home and international students. Returns the official statutory fee levels published for a country and academic year: the most common annual fee, the minimum and the maximum, in national currency with a euro equivalent. These are posted fee levels set by law or by universities, not what any one student paid and not a range built from sales: there is no sample size. How fresh: Canada: annual: one value per academic year (2026/2027 was published on 16 September 2026); every answer names its academic year; Europe: academic year 2023/24 (Eurydice release of September 2025); updated about once a year; Taiwan: annual: one value per academic year (the Ministry updates the file every October for the new year); every answer names its academic year. Fees are before grants, loans and fee waivers. Do not use for the price of one named course or university, living costs or rent, school fees, or countries that are not listed.

Use this when a user asks what the wholesale price of live pigs, cattle or chickens, fish, eggs or other fresh food is today in Australia (country AU), Canada (country CA), Germany (country DE), France (country FR), England and Wales (country GB), Hong Kong (country HK) or Malaysia (country MY), or how it moved on the previous day. Returns the newest daily average reference wholesale price that the government publishes for the food type, per kilogram or per egg, with the day it applies to, the change on the previous published day, the recent days, the official source and licence. This is a posted reference price reported by wholesalers (price_type posted_price), not a paid price and not a range built from sales, so the range fields are null and there is no sample size. How fresh: Australia: daily on trading days (MLA updates at midnight AEST); every answer states the trading day it describes; Canada: weekly (a Friday date); our copy is refreshed daily and each answer states the week its quotes apply to; Germany: weekly (calendar week); each answer states the week its price applies to; France: daily on market days (each market line carries its own date); each answer states the dates its quotes apply to; England and Wales: about every two weeks (a Monday date); each answer states the date its price applies to; Hong Kong: daily on working days, published by the AFCD when necessary; each answer states the day its price applies to; Malaysia: monthly, not live: the catalogue is refreshed after each month closes (catalogue last updated 10 October 2026 when checked); our copy is refreshed daily and every answer names its month. Do not use for supermarket or shop prices, for the price one farm received, for restaurant prices, for futures prices, or for other countries.

Use this when a user asks what traders paid for vegetables or fruit (cabbage, tomatoes, cucumbers, onions, bananas, pineapples, guavas, melons, grapes...) at the wholesale produce markets of Taiwan (country TW), or what the price range at the wholesale market was this week. Returns a range built from the market's own daily trading records (median, 10th to 90th percentile, lowest and highest, number of records) for the newest few days, per kilogram, with the volume traded, the markets included and the official source and licence. A record is the average price of one variety at one market on one day. How fresh: daily, trading days only (a closed market publishes nothing). These are wholesale prices between traders, not what a shopper pays and not what a farmer receives. Do not use for supermarket or shop prices, for the price one farm received, for flowers, meat or fish, for futures prices, or for other countries.

Use this when a user asks what electricity costs on the wholesale (day-ahead power exchange) market in Australia, Germany, Spain and Portugal, Austria, Belgium, Denmark, France, northern Italy, the Netherlands, south-west Norway and Poland or Great Britain: the recent median, the typical range across hours, the cheapest and dearest hour, the latest hour and how many hours had negative prices. Prices are in euro per MWh (1 MWh = 1000 kWh; the answer also gives cents per kWh). Built from the hourly auction prices of the recent days, with the official source and licence. How fresh: Australia: AEMO publishes one price file per trading day (04:00 to 04:00 NEM time) early the next morning; ProofPrice reads the files of the last days on each request (cached up to 30 minutes); Germany: hourly prices, published the day before delivery (around 13:00 Central European Time); ProofPrice reads them on each request (cached up to 30 minutes); Spain and Portugal and Austria, Belgium, Denmark, France, northern Italy, the Netherlands, south-west Norway and Poland: prices are published the day before delivery (around 13:00 Central European Time); ProofPrice reads them on each request (cached up to 30 minutes); Great Britain: half-hourly prices appear within hours of each trading period and are read on each request (cached up to 30 minutes). Wholesale prices are not what households or businesses pay on their bills. Do not use for retail tariffs, for petrol and diesel, or for other countries.

Use this when a user asks how wholesale electricity prices have changed over recent days or weeks in a country, or whether power is getting cheaper. Returns the daily median and typical range of hourly day-ahead prices in euro per MWh, with the change over the period, from our daily snapshots of official data. Do not use for household bills. After 10 free calls a day per caller this tool costs USD 0.02 per answered call, paid with x402 (USDC); a 402 reply lists how. Nothing is charged for "not enough records" or errors.

Use this before paying: when a user or agent has a proposed price for something (a rent, a home, a litre of fuel, a medicine, a contract) and wants to know whether it is typical against recorded official evidence. Give the category (border-prices, broadband, cars, childcare, commercial-property, construction, contracts, diet-costs, energy, farm-gate-prices, farm-prices, flights, fuel, groceries, health-insurance, home-sales, home-upgrades, hotels, insurance, land-prices, medical, medicines, price-levels, producer-prices, rent, surplus-auctions, tuition, wholesale-fresh-food, wholesale-markets and wholesale-power), the country, the same parameters that category's own tool takes, and the price. It runs the category's normal answer and returns a verdict: within, above or below the typical range (10th–90th percentile of recorded prices) when the evidence is a set of records; about, above or below the average when the evidence is one official average or median (within 5% counts as about average, and it says plainly this is an average, not a distribution); or cannot_judge, with the reason, when the currency or unit differs (ProofPrice never converts), there are too few records or nothing matched. It also returns where the price sits (for example '27% above the median and above the 90th percentile'), the reasons and cautions (posted prices are not paid prices, old periods), what is missing, one quotable sentence, and the full evidence answer with source, licence and audit-trail fields to keep with the reasoning. Do not use it to value one specific item or address, as financial or legal advice, or to compare prices in different currencies or units. After 20 free calls a day per caller this tool costs USD 0.10 per answered call, paid with x402 (USDC); a 402 reply lists how. Nothing is charged for "not enough records" or errors.

Use this to see which countries and kinds of price the tools cover. It returns a short overview: for each tool the countries it answers for, how many official sources stand behind it and how often they update. Give category and/or country to get the full detail of the matching sources instead (publisher, licence, attribution line, limits, example requests).
