The specific resource `/api/v1/medical/records/93` returns JSON content upon payment of USDC on the Base network. The endpoint is live and responds with a standard x402 challenge (HTTP 402) requiring an X-PAYMENT header.\n\nThe provider lowpaymentfee.com hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and utility services. Most listed endpoints are priced at $0.02 per request. However, this particular medical records endpoint advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 — consistent with the site-wide pricing. Payment is made in USDC (contract 0x8335…2913) on Base to address 0x1A2B…85F3, with a 300-second payment timeout.\n\nNo OpenAPI schema, request body documentation, or response examples are available for this endpoint. The crawled pages beyond the landing page returned only a \"Connect wallet\" prompt with no additional documentation. The endpoint accepts POST requests and is marked as discoverable. Because this endpoint is labeled \"medical/records,\" it may involve sensitive or regulated health data — consumers should exercise caution and verify compliance with applicable regulations before use.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","medical-records","json-response","post-method"],"categories":["data","health"],"synonyms":["medical records API","health data endpoint","x402 medical API","USDC pay-per-call","Base network API","lowpaymentfee medical","patient records API"],"warnings":["No API documentation, request schema, or response schema available for this endpoint.","Endpoint serves 'medical records' data — may involve regulated health information (e.g., HIPAA, GDPR).
