It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request. This specific endpoint falls under a \"medical/records\" path, but the crawled landing page does not list it among the advertised API categories, and no documentation, schema, or sample response for this endpoint was found. The exact data returned by this medical records endpoint is unknown — it could be synthetic/demo data or a real medical data service.\n\nBecause this endpoint deals with a path labeled \"medical/records,\" users should exercise caution regarding data accuracy, regulatory compliance (HIPAA, GDPR), and the provenance of any returned data. No OpenAPI spec, request body schema, or response schema is available beyond the x402 challenge metadata.","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-call health records","USDC medical data","Base network API","lowpaymentfee medical"],"warnings":["No documentation or schema available for this specific medical records endpoint","Endpoint path suggests medical/health data — regulatory compliance (HIPAA, GDPR) is unverified","This endpoint is not listed among the provider's advertised APIs on the landing page","No sample request or response data available; returned content is unknown","Could be synthetic or demo data — do not rely on for clinical or production healthcare use"],"endpointUrl":"https://lowpaymentfee.com/api/v1/medical/records/60","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/60","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), but there is no documentation, no request/response schema, no examples, and the medical records path is not listed on the provider's own landing page.
