Pay-per-call employee data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record #31) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 0.02 USDC per request (20,000 base units at 6 decimals).
The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no minimum commitments.
This specific endpoint (/api/v1/employees/31) is not individually documented on the site's landing page, and no OpenAPI schema, request/response examples, or detailed documentation were found. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no additional content. As a result, the exact request format and response structure for this employee endpoint are unknown and must be discovered by the caller.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and no meaningful documentation beyond the landing page listing. The specific /employees/31 path isn't even listed on the site. This is effectively a stub listing.
