The specific endpoint probed appears to serve medical record data (record ID 91), accepting POST requests and returning JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 \"exact\" scheme.\n\nThe x402 challenge advertises a `maxAmountRequired` of 20,000 base units. Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the site-wide pricing of $0.02/request displayed on the landing page. The platform advertises no API keys, no rate limits, and instant access — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nImportant caveat: the endpoint path suggests it returns medical records, which falls into a regulated data category (health/PHI). No documentation, OpenAPI schema, or example responses were found in the crawl. The landing page lists many API categories but does not specifically list or describe this medical records endpoint, so its actual data content, input parameters, and response format are unknown. Treat with caution.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","medical-records","json-response","post-method"],"categories":["health","data"],"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":["Medical/health data endpoint with no HIPAA or compliance documentation found","Endpoint path /api/v1/medical/records/91 is not listed on the provider's landing page among advertised APIs","No OpenAPI spec, request schema, or response schema available — input parameters and output format are completely unknown","Regulated data category: callers should verify legal and compliance requirements before use","No robots.txt or agents.txt found; no usage terms documented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/medical/records/91","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/91","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 captured) and pricing is clear ($0.02 USDC on Base).
