Market402 x402 Index & Mart402 (free tools)
Claude connectorCommunityCheck x402 pay-per-call API sellers before you rely on them: search a measured index of x402 endpoints and see each operator's track record…
Market402 x402 Index & Mart402 (free tools) gives Claude read-only access to a measured index of the x402 pay-per-call economy and to a few free utilities. Nothing in this connector charges, asks for payment or moves money.
Main use - check a seller before you rely on it:
- search_x402_services searches Market402, which probes listed x402 endpoints every week and
publishes a 402 Score, grade, badge, price and delivery checks (backed by on-chain transaction hashes) under one public methodology applied to every operator (https://market402.com/methodology).
- operator_history shows one operator's 12-week track record: weekly scores, trend, volatility and badge history.
Also free:
- quote_parse returns the exact price, page count and route (text or scanned) of a PDF before
any purchase.
- portrait_precheck tells whether a photo is usable for color analysis (no identification).
- get_catalog and get_sample show Mart402's product list, policies and recorded sample outputs.
Market402 and Mart402 are run by the same operator. All tools are read-only and require no account or API key.
Market402 x402 Index & Mart402 (free tools) is #9,591 of 11,065 Claude connectors by popularity, down 1,101 places in a week.
