Pay-per-call EHR API endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at `/api/v1/ehr/9` is part of the lowpaymentfee.com platform, which offers a collection of pay-per-request APIs spanning data analytics, AI/ML, finance, infrastructure utilities, and more. All endpoints use the x402 payment protocol, settling in USDC on the Base network. The platform advertises a flat $0.02 per request with no API keys, no rate limits, and instant access.
The specific `/api/v1/ehr/9` path suggests an Electronic Health Record (EHR) resource, though it is not listed among the publicly advertised API categories on the site's landing page. The x402 challenge confirms the endpoint is live, accepts POST requests, and requires payment of up to 20,000 base units of USDC (0.02 USD) on Base. The payment is made via the x402 "exact" scheme to the specified wallet address.
Documentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what data this EHR endpoint returns or what input it expects. The endpoint's purpose and data format must be treated as unknown until further documentation is provided.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no schema, no request/response examples, and the EHR endpoint is not even listed on the provider's own landing page. The purpose and data format are entirely unknown.
Warnings
- —The /api/v1/ehr/9 endpoint is not listed among the provider's publicly advertised APIs — its existence and purpose are unverified beyond the 402 challenge.
- —No documentation, OpenAPI schema, or request/response examples are available; all docs pages render only 'Connect wallet'.
- —EHR (Electronic Health Record) data may be subject to healthcare regulations (e.g., HIPAA). No compliance or data-handling information is provided.
- —The endpoint path includes a numeric ID (9), which may refer to a specific record — unclear if this is a demo, synthetic data, or real patient data.
