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).\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 with no API keys, no rate limits, and no commitments. This specific endpoint sits under the `/api/v1/medical/records/` path, suggesting it returns structured medical record data for the given record identifier.\n\nNo OpenAPI schema, request/response examples, or detailed documentation were found for this endpoint. The x402 challenge is live and well-formed, confirming the endpoint is operational. However, the medical records path was not listed on the provider's landing page among the advertised API categories, and no documentation describes the expected input or output format. Because this endpoint deals with medical data, consumers should exercise caution regarding regulatory compliance (HIPAA, GDPR, etc.).","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","medical-records","json-response","pay-per-call","no-api-key"],"categories":["health","data"],"synonyms":["medical records API","health data endpoint","patient records","x402 medical API","USDC pay-per-call","lowpaymentfee medical","Base network API"],"warnings":["No documentation or schema available for this endpoint — input/output format is unknown.","Medical data endpoint: consumers must independently verify regulatory compliance (HIPAA, GDPR, etc.).","This specific path (/api/v1/medical/records/36) is not listed among the provider's advertised APIs on the landing page.","No privacy policy, terms of service, or BAA information found on the provider site."],"endpointUrl":"https://lowpaymentfee.com/api/v1/medical/records/36","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/36","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response documentation, and no examples.
