All endpoints use the x402 payment protocol, settling in USDC on the Base network with no API keys, no rate limits, and no subscriptions required.\n\nThe specific resource at path `/medical/records/96` is labeled \"Premium API Access\" and costs up to $0.02 per request (maxAmountRequired of 20,000 base units of USDC, which has 6 decimals = $0.02). It accepts POST requests and returns `application/json`. The endpoint is live, returning a proper 402 challenge with x402 version 1. Payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using the USDC contract on Base (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`).\n\nNote: The endpoint path suggests medical records data, but no documentation, schema, or sample responses are available to confirm what data is actually returned. The provider's landing page does not list this specific endpoint among its advertised APIs, and the \"medical/records\" category is not mentioned elsewhere on the site. Treat the actual response content as unverified until you can inspect a paid response.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","medical-records","json-response","no-api-key","post-method"],"categories":["data","health"],"synonyms":["medical records API","health data endpoint","x402 medical API","pay-per-call health records","USDC medical data","lowpaymentfee medical","Base network health API"],"warnings":["No documentation or response schema available for this endpoint","The /medical/records/ path is not listed among the provider's advertised APIs on the landing page","Endpoint claims to serve medical records but no compliance, data source, or privacy information is provided","Response content is entirely unverified — pay before you can inspect what is returned","Regulated category (health/medical data): verify data provenance and compliance before use in any production context"],"endpointUrl":"https://lowpaymentfee.com/api/v1/medical/records/96","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/96","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but there is no documentation, no OpenAPI schema, no example request/response, and the medical records category is not listed on the provider's own landing page.
