x402-gated medical records endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a medical records resource (record ID 7) via the x402 payment protocol. The endpoint is live and returns a 402 challenge requiring payment in USDC on the Base network. The maximum amount required per request is 20,000 base units of USDC (6 decimals), which equals $0.02 USD per call. Payment is made via the x402 "exact" scheme to a specified wallet address, with a 300-second timeout window.
The provider site (lowpaymentfee.com) hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint being listed here (/api/v1/medical/records/7) is not explicitly documented on the provider's landing page among the advertised API categories. Its description in the x402 challenge is simply "Premium API Access" and the MIME type is application/json. No request body schema, response schema, or further documentation is available for this particular endpoint.
Because this endpoint deals with medical records, it falls into a regulated data category. There is no documentation about data provenance, compliance (e.g., HIPAA), or what the returned record actually contains. Consumers should exercise caution and verify the nature and legality of the data before use.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no request/response schema, no documentation for this specific medical records endpoint, and the endpoint is not listed among the provider's advertised APIs. The regulated nature of medical data without any compliance information further lowers confidence.
