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 70) 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 provider site (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. This specific endpoint falls under a "medical/records" path, but no documentation, schema, or sample response for the medical records endpoints was found in the crawled material. The exact fields returned and the nature of the medical data are unknown.
Because the endpoint deals with medical records, consumers should exercise caution regarding data provenance, accuracy, and regulatory compliance (e.g., HIPAA in the US). No privacy policy, terms of service, or compliance documentation was discovered during the crawl.
