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 16) behind an x402 paywall. 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 on the Base network using USDC.
The specific endpoint `/api/v1/hr/documents/16` 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 crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no description of request parameters, and no sample responses for this or any other endpoint on the platform. The endpoint's purpose — serving an "HR document" — is inferred solely from the URL path; no further detail about the document's content or format is available.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no request/response examples, and the purpose of the endpoint is only inferable from the URL path. The docs pages are empty. This is effectively a stub listing.
Warnings
- —No documentation available — all doc/pricing/README pages return only 'Connect wallet' with no content.
- —No OpenAPI or request/response schema provided; request parameters and response format are unknown.
- —The endpoint's purpose ('HR documents') is inferred solely from the URL path; actual content is unverified.
- —The broader platform lists many endpoints but none have documented schemas or examples.
