x402-gated EHR endpoint on Base, pay-per-request with USDC — no API keys required.
What it does
This endpoint at `/api/v1/ehr/60` is part of the lowpaymentfee.com platform, a collection of x402-protocol pay-per-call APIs spanning data analytics, AI/ML, finance, infrastructure, and more. The specific `/ehr/60` path suggests an Electronic Health Record (EHR) resource, though the provider's landing page does not explicitly list or document this particular endpoint. The platform advertises a uniform $0.02 per request pricing model across its API catalog.
The endpoint is live and returns a valid x402 challenge on POST. Payment is settled in USDC on the Base network (asset `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) using the "exact" scheme. The `maxAmountRequired` is 20000 base units, which at 6 decimals equals $0.02 — consistent with the site-wide pricing. No API keys, rate limits, or subscriptions are required; callers simply attach an `X-PAYMENT` header with a valid x402 payment proof.
Documentation is extremely sparse. The docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the `/ehr/60` endpoint actually returns. The "EHR" path segment and the number 60 are not explained anywhere in the crawled material. Callers should treat this as an exploratory endpoint until the provider publishes proper documentation.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is zero documentation for this specific endpoint — no schema, no examples, no explanation of what 'ehr/60' returns. The docs pages are empty. The endpoint path is not even listed on the provider's landing page, making this effectively a stub listing.
