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 uniformly at $0.02 per request. This specific endpoint sits under the /api/v1/medical/records path, though it is not listed on the provider's public landing page among the advertised API categories. The endpoint is live and returns a proper 402 challenge with x402 version 1.\n\nBecause the endpoint deals with medical records, callers should be aware of potential regulatory considerations (e.g., HIPAA in the US, GDPR in the EU). No documentation, request schema, or response schema is provided beyond the x402 challenge metadata. The actual data returned and the expected POST body are unknown.","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":["This endpoint serves medical records — callers should verify regulatory compliance (HIPAA, GDPR, etc.) independently.","The /api/v1/medical/records path is not listed among the provider's publicly advertised APIs; its legitimacy and data source are unverified.","No request body schema or response schema is documented; the expected POST payload is unknown.","No OpenAPI spec, README, or detailed docs are available from the provider."],"endpointUrl":"https://lowpaymentfee.com/api/v1/medical/records/98","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/98","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, but there is no request/response schema, no documentation, and the medical records path is not listed on the provider's own landing page.
