Pay-per-call medical records endpoint on Base via x402, settled in USDC.
What it does
This endpoint at `/api/v1/medical/records/26` is part of the lowpaymentfee.com platform, which offers a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and infrastructure utilities. 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.
The specific resource at `/api/v1/medical/records/26` is listed under the title "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 `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, using the USDC contract at `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`. The response MIME type is `application/json`.
Important caveats: the endpoint path suggests it returns medical records, which is a regulated data category. No documentation, request schema, or response schema is provided beyond the x402 challenge metadata. There is no OpenAPI spec, no example payloads, and the crawled docs pages (`/api`, `/pricing`, `/README`) all returned only a "Connect wallet" prompt with no substantive content. The nature and provenance of the medical data served is entirely unknown.
