All endpoints use the x402 protocol for payment, settling in USDC on the Base network with no API keys, no rate limits, and no subscriptions required.\n\nThe specific resource at `/api/v1/medical/records/78` is labeled \"Premium API Access\" and accepts POST requests. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0.02 USD per request, since USDC uses 6 decimals). Payment is sent to the on-chain address `0x1A2B...85F3` on Base, with a timeout of 300 seconds. The response MIME type is `application/json`.\n\nImportant caveats: the endpoint path suggests it returns medical records, which falls into a regulated data category (health/PHI). No documentation, OpenAPI schema, or example responses are available beyond the x402 challenge metadata and the landing page listing. There is no information about what data is actually returned, what POST body is expected, or whether the data involves real patient information. Prospective users should exercise caution and verify compliance with applicable health data regulations before use.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","medical-records","pay-per-request","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","lowpaymentfee medical","Base network health API"],"warnings":["Endpoint path suggests medical/health records — regulated data category (HIPAA, GDPR health provisions).
