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 6) behind an x402 payment wall. It accepts POST requests and returns JSON content upon payment of $0.02 in USDC on the Base network. The endpoint is part of a broader platform that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services—all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.
The x402 challenge confirms the endpoint is live and uses the "exact" payment scheme, settling to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The maximum amount required is 20,000 base units, which at 6 decimals equals $0.02. The timeout is 300 seconds.
The specific content of the HR document at `/api/v1/hr/documents/6` is not documented in the crawled material. The landing page lists this endpoint's category implicitly under a broader set of APIs but does not describe the HR documents collection specifically. No OpenAPI schema, request body format, or response schema is available, so the exact fields expected in the POST body and the structure of the returned document are unknown.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation on what the HR document contains, no request/response schema, and the crawled pages provide no detail about the /hr/documents/ collection. Effectively a stub listing.
