x402-gated HR document endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at `/api/v1/hr/documents/35` 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 resource appears to serve an HR document (document ID 35) behind a paywall. Payment is settled on the Base network using USDC (contract `0x8335…2913`) via the x402 exact-payment scheme. The maximum amount required per request is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). The endpoint accepts POST requests and returns `application/json`.
The broader lowpaymentfee.com platform advertises a uniform $0.02-per-request pricing model across all its endpoints, with no API keys, no rate limits, and no minimum commitments. However, the specific content and schema of the HR documents endpoint is not documented — there is no OpenAPI spec, no request/response schema, and no example payloads available from the crawled material. The endpoint is confirmed live via a valid 402 challenge response. Because the endpoint path suggests a single static document resource (document ID 35), it may return a fixed HR document rather than accepting query parameters, but this is speculative given the lack of documentation.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 per request in USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation of what the HR document contains or what POST body (if any) is expected, and the crawled pages beyond the homepage returned only 'Connect wallet' with no useful content. The endpoint path suggests a single static resource with unclear utility.
