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 48) behind an x402 payment wall. It is part of a broader platform that offers dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all settled via USDC on the Base network using the x402 protocol.
The specific endpoint `/api/v1/hr/documents/48` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (asset 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, API, pricing, 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 HR document resource actually contains or what input parameters the POST body expects. The endpoint is confirmed live (returns a proper 402 challenge), but without documentation it is unclear what data is returned or what request body format is needed.

Quality
The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02/request in USDC on Base). However, there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what the HR document resource actually contains or what POST body is expected. This is effectively a stub listing.
