Pay-per-call medical records endpoint on Base via x402, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a medical records resource (record ID 8) via the x402 payment protocol. 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.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers numerous pay-per-call APIs across categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. However, the specific endpoint being listed here — `/api/v1/medical/records/8` — is not documented on the provider's landing page among the advertised API categories. Its exact response schema and the nature of the medical record data it returns are unknown from the available material.
The x402 challenge was successfully captured (HTTP 402 with valid accepts array), confirming the endpoint is live. The payment timeout is 300 seconds. No OpenAPI specification, detailed documentation, or example responses were found for this specific endpoint.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but this specific medical records endpoint is not documented on the provider's site, has no OpenAPI schema, no example request/response, and the nature of the data returned is entirely unknown. The medical/health category also raises regulatory concerns.
