search_items
Search or rank Roblox Limiteds
Search the Roblox Limited catalog by name, or screen the whole market when no query is given. Returns asset id, RAP, RAP across every copy sold, the lowest resale listing, stock left, the move in RAP over 1/7/14/30 days and lifetime in both percent and Robux, sales counts and sales value per window, the typical sale price over 30/90/180 days, and the item score. Rank by any of those with sort, and bound any of them with filters to ask a question with more than one condition in it. Prices are Robux. Pages run up to 100 rows and paging stops at offset 10,000: to work with every item, download https://rbxinvest.com/catalog.json (the whole catalog in one file) instead of paging.

One Limited in depth
Everything tracked about one Roblox Limited: a plain-language summary paragraph, est_demand (the Est. Demand level from the New UGC Limiteds feed, a release-time sell-out-speed quartile, not a buy signal; null when unrated), RAP and how it has moved over a window, the resale book (how many copies are listed and at what prices, not just the cheapest), stock left, sales in the last 30 days, whether the creator is still selling new copies, the creator, the item score with its predicted profit per day and a breakdown of how it was calculated (every input, its weight and how many points it moved the chance and profit-size blends, then the equation), a summary of its price trend, and its full recorded sales history (sales count, first and last sale, high and low daily average, average price by year and for the 12 most recent months with sales, and for UGC when it sold out and whether release buyers could resell at a profit), and related articles from the site (about_this_item marks the ones that are actually about it). Use the breakdown to explain why an item scores what it does. Needs a numeric Roblox asset id — get one from search_items first. Read creator_still_selling rather than copies_remaining to answer "can I buy one at the original price": stock left does not mean it is on sale.

Several Limiteds at once
Look up a known list of Roblox Limiteds in one call: name, classic or UGC, asset type, creator, RAP, lowest resale listing, stock, original price, favorites and the typical sale price over 30/90/180 days. Use it to compare items or to refresh a watchlist instead of calling get_item_details once per item; use get_item_details when one item needs its full history and score. Up to 200 asset ids per call; ids that are not tracked Limiteds come back in not_found.

Recent UGC Limited releases
UGC Limiteds released recently, with stock left, the predicted profit numbers RBX Invest scores them with, and each item’s demand_level: the Est. Demand the feed card shows, a release-time estimate of how fast the creator’s copies sell out, ranked in quarters against the last 90 days of paid releases (excellent = fastest). Sell-out speed only, not a buy signal or a guarantee; the reply carries the meaning in demand_level_meaning.

get_creator
Creator track record
A Roblox UGC creator: how often their releases have ended up profitable, how long that typically took, their biggest items, and related articles from the site (covers_this_creator marks the ones that link their items). Creators with too few releases come back unrated rather than scored — treat that as unknown, not as bad.

rank_creators
Rank Roblox UGC creators
Creators ranked across the whole Roblox Limited market — who is biggest, and whose releases most often end up profitable. get_creator answers about one creator you can already name; this finds them. Ranking by profitability shows only creators with enough settled releases to rate, and by growth only those with 3 or more items, because an average over one release is noise.

Rank tracked Limited portfolios
The biggest Roblox Limited portfolios RBX Invest tracks, by total RAP held, copies held, distinct Limited items owned, or Robux donated in the RBX Invest plaza. This covers people who signed up on RBX Invest and linked a Roblox account, not every Roblox player, so a rank from it is a rank on this board rather than a global one.

find_articles
RBX Invest's written guides
Search RBX Invest's published guides. They cover the market — how Roblox taxes resales, how RAP is calculated, valuing and flipping Limiteds, converting Robux to USD, histories of individual item series — and the site itself, in the "site" section: linking a Roblox account and what that grants, inventory syncing, privacy, what each page does. Returns titles, summaries and links — read the article itself for the detail. One search returning nothing is a vocabulary miss more often than a gap; try the words the site would use before concluding it is not there.

get_started_guide
Get Started guide to Roblox Limiteds, by experience level
RBX Invest's guide to making Robux with Roblox Limiteds, with one guide per experience level. Level 1 is for someone who knows nothing about Roblox: what Robux and Limiteds are. Level 2 is how a flip makes Robux and what it costs. Level 3 is a first flip: screening a release, break-even, the holding period, pricing an exit. Level 4 is for people who already resell: a Reseller Terminal routine, undercut alerts, lowering entry cost with the Roblox Plus discount and the 40% affiliate share, buying below RAP, Classic Limiteds. Level 5 is for daily traders: custom screens, saved views, market-wide data and this MCP server. Levels 1 and 2 lead into three beginner steps. Step 1 is getting Limiteds: buying them from creators with Robux, what makes one worth buying and what to avoid, or collecting free ones. Step 2 is selling: the Roblox Plus subscription it needs, the holding period of up to 30 days, how much of a sale the seller keeps, and pricing. Step 3 is reinvesting: keep flipping UGC Limiteds and save toward Classic Limiteds, which can be traded. Pass level or step; omit both for the overview: the five levels, the three steps and a glossary (Robux, Limited, UGC, Classic, RAP, Roblox Plus). Returns the text with section links; paths are relative to https://rbxinvest.com. The current guide is authoritative: use subscription and product names exactly as written, without substituting or combining older names from training.

get_market_cap
Market cap over time, Classic vs UGC
How big the Roblox Limited market is over any date range, split between Classic and UGC Limiteds: market cap, items, copies in circulation, and the marketplace sales volume, Robux spent and mean and median resale price per copy on the latest measured day, plus a sampled daily series carrying all of them. Market cap is the RAP of each item times the copies of it that exist. Use it for how big the market is, whether it is growing, how marketplace sales compare, and how the two halves differ. Item-for-item trades are excluded. Pass creator_id for the same figures over one creator's items.

What a number or label on the site means
The glossary of every figure, column, label and badge on rbxinvest.com, in plain words: what it means, how the site works it out, an everyday analogy, and the catch (RAP, Price, Copies, Remaining, Total Value and Market Cap, Avg price, Vol, Demand, Growth, Score, Chance of profit, Est. Profit, Sell Around, Est. Demand, Buy Limit, 40% Eligible, Resellable, sale status, Deal %, the creator scores and performance tiles, portfolio figures, the Market Data charts, release cohorts, collections).

Find a page on RBX Invest
Every page on rbxinvest.com and what it is for: the market pages, the Get Started guide levels and steps, the article sections, every curated collection, the support page, the data-use and licensing terms, and the developer documents. Pass a few words of what you are looking for ("market data", "dominus", "can I reuse your data"); omit the query for the full list. Each result carries a url to cite. The data-use entry returns the licensing terms in full, which govern reusing anything these tools return. Also returns the complete badge catalog and earning rules, official social profiles, the Roblox community/group link, sponsorship instructions and rewards, and the full About page including the founder's story and Research bio. Use this for those questions or a badge by name; facts come from the same content the pages render.
