Pay-per-call employee data API on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee data records via the x402 payment protocol. The specific resource `/api/v1/employees/2` returns JSON data for employee ID 2 when called with a valid x402 payment header. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The endpoint is part of a broader platform (lowpaymentfee.com) that offers numerous pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. Payment is handled entirely through the x402 protocol's X-PAYMENT header mechanism on the Base L2 network.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee record contains. The endpoint accepts POST requests based on the outputSchema in the 402 challenge, but the actual request body format and response structure are unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documentation beyond a landing page listing, no request/response examples, and the docs pages are empty. The actual data returned by the employee endpoint is completely undocumented.
