Pay-per-call medical records API on Base, settled in USDC via x402.
What it does
This endpoint at lowpaymentfee.com provides access to a medical records resource (record ID 36) 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).
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call 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. This specific endpoint sits under the `/api/v1/medical/records/` path, suggesting it returns structured medical record data for the given record identifier.
No OpenAPI schema, request/response examples, or detailed documentation were found for this endpoint. The x402 challenge is live and well-formed, confirming the endpoint is operational. However, the medical records path was not listed on the provider's landing page among the advertised API categories, and no documentation describes the expected input or output format. Because this endpoint deals with medical data, consumers should exercise caution regarding regulatory compliance (HIPAA, GDPR, etc.).

Quality
