It is accessed via the x402 payment protocol, settling on the Base network using USDC. The x402 challenge confirms the endpoint is live and requires a payment of 20,000 base units of USDC (i.e., $0.02) per request.\n\nThe provider's landing page advertises a wide range of API categories — data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. This specific endpoint appears under a \"medical/records\" path, but no documentation, schema, or sample payloads are available for it. The endpoint accepts HTTP POST and returns `application/json`. No API keys or rate limits are advertised; access is gated entirely by x402 micropayment.\n\nBecause no request or response schema is documented, and the medical records path suggests handling of sensitive health data, callers should exercise caution. There is no visible privacy policy, HIPAA disclosure, or data-handling documentation on the provider's site. The actual content returned by this endpoint is unknown — it may be synthetic/demo data or a placeholder.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-call","medical-records","json-api","no-api-key","http-post"],"categories":["data","health"],"synonyms":["medical records API","health data endpoint","x402 medical API","pay-per-call health records","USDC micropayment API","Base network API","lowpaymentfee medical"],"warnings":["No request or response schema documented for this endpoint","Path suggests medical/health data but no HIPAA, privacy policy, or data-handling disclosures are visible","The provider site shows only 'Connect wallet' on /api, /pricing, and /README pages — effectively no documentation","Endpoint may return synthetic or placeholder data; actual content is unknown","This endpoint is one of many on a generic multi-category API platform — specificity of the medical records offering is unverified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/medical/records/81","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/81","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base).
