x402-gated medical records endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a medical records resource (record ID 11) via the x402 payment protocol. The endpoint is live and returns a 402 challenge requiring payment in USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). Payment is made via the x402 "exact" scheme to a specified wallet address, with a timeout of 300 seconds.
The provider's landing page advertises a broad catalog of x402-gated APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and instant access. However, the specific endpoint being listed here (/api/v1/medical/records/11) is not mentioned on the landing page catalog, and no documentation, request/response schema, or examples are provided for it. The "medical/records" path suggests health-related data, but the actual content and format of the response are unknown.
Because there is no OpenAPI spec, no documented request body schema, and no sample responses, the exact functionality and data returned by this endpoint remain unclear. Agents should treat this as an opaque paid endpoint until further documentation is available.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation for this specific medical records path, and the endpoint is not listed in the provider's own catalog. The medical/health category raises regulatory concerns with zero compliance information.
