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 24) 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, infrastructure utilities, and more — all settled on the Base network using USDC.
The specific endpoint `/api/v1/hr/documents/24` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 per request — consistent with the platform's uniform $0.02/request pricing. Payment is made via the x402 exact scheme with a 300-second timeout. No API keys or rate limits are required; access is instant once payment is included in the X-PAYMENT header.
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 schema, no request/response examples, and no description of what the HR document endpoint actually returns. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know the expected input body or output format beyond `application/json`.

Quality
The endpoint is confirmed live with a valid x402 challenge and clear pricing ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documentation, no request/response examples, and no description of what the HR document endpoint actually returns. The docs pages are empty beyond a wallet-connect prompt. This is effectively a stub listing.
Warnings
- —No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
- —No OpenAPI or schema describing request body or response format
- —Purpose of 'HR documents/24' endpoint is unclear — no description of what data is returned
- —No request or response examples available anywhere in crawled content
