The endpoint is live and returns a 402 challenge requiring payment in USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). Payment is made via the x402 \"exact\" scheme to a specified wallet address, with a timeout of 300 seconds.\n\nThe provider's landing page advertises a broad catalog of x402-gated APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and instant access. However, the specific endpoint being listed here (/api/v1/medical/records/11) is not mentioned on the landing page catalog, and no documentation, request/response schema, or examples are provided for it. The \"medical/records\" path suggests health-related data, but the actual content and format of the response are unknown.\n\nBecause there is no OpenAPI spec, no documented request body schema, and no sample responses, the exact functionality and data returned by this endpoint remain unclear. Agents should treat this as an opaque paid endpoint until further documentation is available.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","medical-records","per-request-pricing","no-api-key"],"categories":["health","data"],"synonyms":["medical records API","health data endpoint","x402 medical API","paid medical records","USDC medical API","lowpaymentfee medical"],"warnings":["No documentation or schema available for /api/v1/medical/records/11","This endpoint is not listed in the provider's own landing page catalog of APIs","Medical/health data category — no HIPAA or regulatory compliance information provided","No example request or response bodies available; actual data content is unknown","The endpoint path suggests access to a single hardcoded record (ID 11); unclear if other IDs are supported"],"endpointUrl":"https://lowpaymentfee.com/api/v1/medical/records/11","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/medical/records/11","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base).
