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 site (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 no documentation, schema, or sample response for the medical records endpoints was found in the crawled material. The exact fields returned and the nature of the medical data are unknown.\n\nBecause the endpoint deals with medical records, consumers should exercise caution regarding data provenance, accuracy, and regulatory compliance (e.g., HIPAA in the US). No privacy policy, terms of service, or compliance documentation was discovered during the crawl.","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 response schema found for the /api/v1/medical/records/ path","Medical/health data endpoint with no visible HIPAA compliance, privacy policy, or terms of service","Data provenance and accuracy of medical records is completely unknown","The crawled pages beyond the homepage returned only 'Connect wallet' with no useful content","No OpenAPI spec, AI plugin manifest, or agents.txt discovered"],"endpointUrl":"https://lowpaymentfee.com/api/v1/medical/records/70","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/70","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, and no explanation of what medical data is returned.
