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 46) behind an x402 paywall. 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 (lowpaymentfee.com) that offers a variety 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 was successfully captured, confirming the endpoint is live. Payment is settled on-chain via USDC (contract 0x8335…2913) on Base to address 0x1A2B…85F3, using the "exact" scheme with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The response MIME type is application/json. No OpenAPI schema, detailed documentation, or example responses were found for this specific endpoint, so the exact structure of the returned HR document is unknown. The broader site's /api, /pricing, and /README pages all resolve to a minimal "Connect wallet" prompt with no additional documentation.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation for this specific HR document endpoint, no example request/response bodies, and the broader site pages are empty beyond a wallet-connect prompt. The nature of the "HR document" content is entirely opaque.
