x402-gated EHR endpoint on Base, pay $0.02 per request in USDC — no API keys required.
What it does
This endpoint at lowpaymentfee.com provides premium API access to an Electronic Health Record (EHR) resource via the x402 payment protocol. The specific resource path `/api/v1/ehr/5` suggests retrieval or interaction with a particular EHR record (ID 5). Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). The endpoint accepts POST requests and returns application/json.
The broader lowpaymentfee.com platform advertises a wide catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced uniformly at $0.02 per call. The platform emphasizes a no-API-key, no-rate-limit, pay-per-use model with instant access. However, documentation beyond the landing page is essentially empty (all doc/pricing/README pages only show a "Connect wallet" prompt), so there is no detailed schema, field-level documentation, or example responses available for this specific EHR endpoint.
Because the endpoint path references EHR (Electronic Health Records), this likely involves health-related data. No information is provided about data provenance, compliance (HIPAA, etc.), or whether the data is synthetic/demo versus real patient records. Consumers should exercise caution and verify the nature of the data before relying on it for any health-related application.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation for the EHR endpoint — no request/response schema, no examples, no explanation of what data is returned. All documentation pages render only a wallet-connect prompt. The health data context raises compliance concerns that are completely unaddressed.
Warnings
- —No documentation available — all doc pages show only 'Connect wallet' with no content
- —EHR (Electronic Health Record) data may be subject to HIPAA or other health data regulations; no compliance information is provided
- —No request or response schema is documented for this endpoint
- —Unknown whether data is real patient data or synthetic/demo data
- —The specific resource '/api/v1/ehr/5' is not listed on the provider's landing page catalog, raising questions about its intended availability
