x402-gated HR document endpoint on Base, pay-per-request with USDC at $0.02
What it does
This endpoint at lowpaymentfee.com provides access to an HR document resource (`/api/v1/hr/documents/2`) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract `0x8335…2913`) via the x402 "exact" scheme. The price per request is $0.02 (20,000 base units at 6 decimals).
The provider lowpaymentfee.com hosts a broader suite of pay-per-call APIs spanning data & analytics, AI/ML (sentiment, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are advertised at $0.02 per request with no API keys, no rate limits, and no minimum commitments.
The specific endpoint being listed (`/api/v1/hr/documents/2`) appears to serve a single HR document resource. No OpenAPI schema, request/response examples, or detailed documentation were found for this endpoint. The exact structure of the returned document and what input parameters (if any) the POST body accepts are unknown. The x402 challenge was successfully captured (HTTP 402), confirming the endpoint is live.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and no documentation for what this HR document endpoint actually returns or accepts. The endpoint path suggests a single static resource. Effectively a stub listing.
