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 14) 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 gated via the x402 protocol on the Base network.
The specific endpoint `/api/v1/hr/documents/14` accepts POST requests and returns JSON. Payment is settled in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base) using the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). The platform advertises a flat $0.02 per request across all its endpoints, with no API keys, no rate limits, and no minimum commitments.
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 documents endpoint actually returns. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know what data is served or what request body is expected.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what 'HR documents/14' actually contains. The docs pages are all empty wallet-connect stubs. This is effectively a stub listing.
Warnings
- —No documentation available — all doc pages render only 'Connect wallet' with no content
- —No OpenAPI or schema describing request body or response format
- —The nature of the 'HR documents' data is completely undocumented — unclear what document 14 contains
- —The endpoint path suggests HR/personnel data which could involve regulated personal information
