Call any x402 endpoint WITHOUT paying and get back what its own 402 challenge says: the real price, asset, network, payTo address, scheme, timeout, and the request schema when the merchant publishes one. Directory listings are written once and go stale; this is the merchant's own current statement of the terms you are about to accept.

Search the whole x402 economy and get a ranked shortlist of services that can do a job, within a budget. Merges Coinbase Bazaar and 402index into one index keyed by canonical resource URL, then answers the three questions a directory does not: CAN this be invoked (only about 5% publish a call spec, and that is a first-class field here, not something you infer from missing keys), is the price REAL (one live listing advertises ten billion dollars a call — implausible prices are excluded as bad…

Price positioning for an x402 service. Describe what you sell (and optionally what you charge) and get the comparable set — named, counted, and listed — plus your exact percentile within it, the full decile ladder of what those comparables charge, how much demand sits in each price band, and a suggested band derived from the comparables rather than asserted.

Describe a goal and a budget; get back a concrete plan of real x402 calls that would accomplish it — exact URLs, HTTP methods, request shapes, per-step prices from the merchants' own 402 challenges where we have verified them, alternates for every step, and a total you can check before committing. Only services that publish a callable request shape are planned; a step with no invokable candidate is returned as an explicit gap rather than a URL and a shrug.

Statistical analysis of any segment of the x402 economy, computed over a merged index of Coinbase Bazaar and 402index overlaid with our own unpaid 402 probes. Returns the full price distribution (min, p10, p25, median, p75, p90, max, mean), demand discounted by payer concentration, what share of the segment can actually be invoked, the network and asset split, host concentration, liveness, and — once history exists — the trend. Every figure is computed in code from named rows;

Competitive position for a single x402 resource. Give a URL that is listed anywhere in the merged index and get back what the index holds on it (including any correction our own unpaid 402 probe made to its advertised price), the peer set derived from its own description, and where it ranks among those peers on price, call volume, payer diversity and callability — plus the mirrors of itself that are listed as separate services.

x402 Buyer: Pay Safely from an Agent Wallet: Decision rules for an AI agent that holds a wallet and receives an HTTP 402 payment request (x402 v2). Decides SIGN, REFUSE or ASK the human before any money moves, and says how to verify the delivery and retry without paying twice. Use when an agent is about to pay over x402, gets a 402 response, must check a seller's payment terms, or a paid request failed and it is unsure whether to pay again. One-time purchase of the SKILL.md file (Agent Skills f…

x402 Endpoint Payment Check. Check an x402 endpoint's 402 payment-required body before you rely on it. Reports whether the contract is payable, whether it is opted in to the Bazaar catalogue, and whether a buying agent can read its input schema by machine. Every defect carries a JSON evidence path. Reads the body you supply; it does not pay or call the endpoint. A PASS is not a correctness guarantee and not a claim that the service is accurate.
