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 20) behind an x402 paywall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with the "exact" payment scheme.
The x402 challenge advertises a maxAmountRequired of 20000 base units. Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the provider's site-wide pricing of $0.02/request across all their API endpoints. The provider advertises no API keys, no rate limits, and instant access — payment is the only authentication mechanism.
The specific endpoint `/api/v1/hr/documents/20` is not listed on the provider's landing page among their documented API categories (Data & Analytics, AI & ML, Finance & Web3, Infrastructure). The "hr/documents" path suggests human-resources or document-related content, but no further documentation, input schema, or response examples are available. The docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional content. Without documentation on what this endpoint actually returns or what input it expects, its practical utility is unclear.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no input/output schema, no examples, and the specific HR documents path is not listed among the provider's advertised APIs. The docs pages are empty beyond a wallet-connect prompt. Effectively a stub listing.
