Why isn't my x402 API in the Bazaar? Listing lint checks an x402 endpoint for Bazaar indexing: one unpaid call validates its 402 PAYMENT-REQUIRED header, discovery metadata, input and output schemas, description limits and service name against the indexing rules, with a fix for each problem. Use when an agent needs to lint an x402 listing before its first settled payment. Price: $0.005 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

402 conformance check for an x402 or MPP API: can buyer agents' SDKs pay it? Checks the x402 v2 requirements (whole-unit amounts, addresses, the token's EIP-712 domain, the same terms on every request), that a malformed payment is refused, any MPP challenge against the paymentauth.org draft, and the live price against the Bazaar and the host's openapi.json. Unpaid requests only; nothing is signed or paid. Price: $1.00 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

Where does my x402 API rank in Bazaar search? Rank check runs the search a buyer agent would run for your task and returns your rank, the competitor listings ahead of you, and the signals where you trail them (payers, calls, description, output example, schema, price). Search rank, SEO and competitor analysis for x402 listings. A three-result sample is free at /v1/seller/rank/sample. Price: $0.01 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

Will buyer agents choose my x402 API? The Machine Buyer Panel is an A/B conversion test: buyer-agent models choose between your offer and its real Bazaar rivals for up to three tasks, across buyer personas and list positions. Returns your win rate with confidence intervals, why you lost, and up to three truthful edits tested on the same trials. Price: $1.00 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

Trust proof for an x402 seller: a signed attestation of your API's sample output, so buyer agents can check it before paying. Agoranome fetches a free sample from your endpoint's host, checks that your paid route on the same host answers with an x402 offer, and signs an attestation of what it saw and when: the sample's SHA-256 and body, and the offer's price, network and pay-to. Buyers check it at a public URL. Price: $0.05 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

What x402 API should I build? The demand gap finder runs up to 150 Bazaar searches phrased the way buyer agents phrase tasks and ranks the unmet demand: tasks whose top results are weak (no listings, few payers, thin descriptions or a poor fit), with the evidence for each. Public Bazaar data only, joined with measured repeat demand per category. Price: $1.00 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

Who pays my x402 API, and do they come back? Customer analytics for an x402 seller from USDC payments on Base: repeat buyers versus one-off and sweep-like payers, revenue per payer and weekly retention cohorts. Use when an agent needs payer analytics for a pay-to address. Agoranome pledges 15% of settled revenue to a cause, verifiable at /impact/ledger. Price: $0.05 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

What are agents buying on x402? A weekly x402 market data and demand report from Bazaar discovery and Base settlements: repeat-use demand by category, demand gaps, movers, price bands and GET vs POST traction, adjusted for sweeps, with cited sources.

Will a new AI model stop buying my x402 API? The model-update watch tests your offer against its real Bazaar rivals with the Machine Buyer Panel now, then re-runs the same test whenever a panel model changes over the next 30 days and flags a drop in your win rate. One payment, no renewal. Status is free at the watch URL; an optional https webhook gets each result. Price: $1.00 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

Fair Offer certification for an x402 API: every claim in your 402's fair-offer block checked against live behaviour. Your public receipts are reconciled against Base, your free sample is attested, the block is checked against the 0.2 schema and across two requests, and the listing price against the Bazaar. Pass or fail, the signed result is published at a public URL. Price: $1.00 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

Continuous Fair Offer certification for an x402 API: the full certification now, then re-run about once a day for 30 days. The public status and badge show the latest check, so a pass is withdrawn the day a check fails, and every check's signed result is published. One payment, no renewal; a seller pays for the checking, never for the outcome. Price: $1.00 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

Buyer drill: red-team an x402 client. Pay once and get a token and nine trap routes on Agoranome's own host, each a $0.001 seller: a correct offer and eight attacks (price switch, lookalike asset, pay-to swap, network switch, instructions in the paid body, slow responder, unsettled 200, ambiguous error). Nothing signed at a trap is settled. Within 24 hours, a signed report: traps refused, traps paid, cents at risk, one certificate line. Use before a client or policy goes live. Price: $1 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

Buyer check before paying an x402 seller: a signed verdict on one offer from what Agoranome already holds. Fair Offer block valid and certified, the pay-to seen for this host and since when, price against listing and quote, verified deliveries, and which policy tiers the offer meets. With tx=, settlement proof after paying: the USDC transfer on Base, whether it matched the quote, and a buyer-side receipt for the commons. Use when an agent needs seller evidence at the moment of payment. Price: $0.01 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.

Did my agent overpay for x402 APIs? The wallet overspend audit reads a buyer wallet's USDC payments on Base and checks each against the payee's listed Bazaar price: payments above the listed price, oversize settlements of 10x or more, and payments to addresses with no listing, totalled per seller. Use when an agent or its operator needs a spend audit of an x402 buyer wallet. Price: $1.00 in USDC per call, paid with x402 inside the tool call. Failed calls aren't charged.
