x402-gated HR document endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com serves an HR document resource (document ID 11) behind an x402 paywall. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all settled on the Base network using USDC.
The specific endpoint `/api/v1/hr/documents/11` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The platform's landing page confirms a flat $0.02/request pricing model across all endpoints, with no API keys, no rate limits, and no minimum commitments required.
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 spec, no request/response schema documentation, and no description of what the HR document endpoint actually returns. The endpoint is live (returns a valid x402 402 challenge), but without documentation it is unclear what input the POST body should contain or what the response payload looks like. The "HR documents" category is not listed on the homepage's API catalog, making this endpoint's purpose and data content uncertain.

Quality
The endpoint is live and returns a valid x402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation, no OpenAPI spec, no request/response schema, and no explanation of what this HR document endpoint actually returns. The docs pages are empty. This is effectively a stub listing.
