It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract `0x8335…2913`) with a maximum amount of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals). No API keys or rate limits are required; access is granted immediately upon payment.\n\nThe provider, lowpaymentfee.com, hosts a broader catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request on the Base network. The specific endpoint listed here targets medical records, though the crawled material does not document the request body schema, response fields, or the nature of the medical data returned. The x402 challenge was successfully captured (HTTP 402 with valid accepts block), confirming the endpoint is live.\n\nBecause the endpoint deals with medical records, consumers should be aware of potential regulatory implications (e.g., HIPAA in the US, GDPR in the EU). No documentation was found describing data provenance, compliance certifications, or the structure of the returned records. The lack of an OpenAPI spec, request/response examples, or any substantive documentation beyond the landing page limits confidence in what this endpoint actually returns.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","medical-records","pay-per-call","no-api-key","json-response"],"categories":["health","data"],"synonyms":["medical records API","health data endpoint","x402 medical API","pay-per-request medical data","USDC medical records","Base network health API"],"warnings":["No request or response schema documented — unknown what data is returned","Medical/health data category may be subject to HIPAA, GDPR, or other regulations; no compliance information found","No OpenAPI spec, no examples, no README content available","The specific record ID '88' is hardcoded in the URL; unclear if other IDs are supported or how to discover them","Provider landing page lists this endpoint category but does not specifically list /medical/records paths"],"endpointUrl":"https://lowpaymentfee.com/api/v1/medical/records/88","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/88","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response schema, no OpenAPI spec, and the medical records domain raises regulatory concerns with no compliance information provided.
