What it does

This endpoint at `/api/v1/ehr/30` is part of the lowpaymentfee.com platform, which offers a broad catalog of x402-protocol pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. The specific `/ehr/30` path suggests an Electronic Health Records (EHR) resource, though the provider's landing page does not explicitly document this particular endpoint or its request/response schema. The listing title is simply "Premium API Access."

The endpoint is live and returns a valid x402 challenge on POST. Payment is settled on the Base network using USDC (contract `0x8335…2913`) with a `maxAmountRequired` of 20,000 base units, which equals $0.02 (USDC uses 6 decimals). This matches the provider's advertised flat rate of $0.02 per request across all endpoints. The platform advertises no API keys, no rate limits, and instant access — callers simply attach an `X-PAYMENT` header with a valid x402 payment proof.

Because the crawled documentation pages (`/docs`, `/api`, `/pricing`, `/README`) all returned only a "Connect wallet" stub with no substantive content, there is no schema documentation, example payloads, or detailed description of what the `/ehr/30` endpoint actually returns. The endpoint's purpose (EHR data) is inferred solely from the URL path. Callers should exercise caution, especially given that health data may be subject to regulatory requirements (HIPAA in the US, GDPR in the EU, etc.).

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request/response schema, no examples, and no explanation of what /ehr/30 actually returns. All doc pages are stubs. The EHR purpose is inferred only from the URL path. Regulated health-data category adds risk.

Warnings

  • —No request or response schema documentation available — all doc pages return only 'Connect wallet' stubs
  • —The endpoint path suggests Electronic Health Records, a regulated data category (HIPAA, GDPR), but no compliance or data-handling documentation is provided
  • —The exact data returned by /api/v1/ehr/30 is unknown; 'EHR' is inferred solely from the URL path
  • —No OpenAPI spec, no AI plugin manifest, and no robots.txt or agents.txt present
