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 records via the x402 payment protocol. The specific resource `/api/v1/employees/5` returns JSON data for employee ID 5 when called with a POST request and a valid X-PAYMENT header containing a USDC payment on the Base network.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. Payment is made in USDC (contract 0x8335…2913) on Base, using the x402 "exact" scheme. There are no API keys, no rate limits, and no subscription commitments; each call is individually settled on-chain.
The x402 challenge confirms the endpoint is live and returns a 402 Payment Required response with a maxAmountRequired of 20000 base units. USDC uses 6 decimals, so this equals $0.02 per request. The payment is directed to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. Documentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail about request/response schemas for this specific employee endpoint.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and all documentation pages beyond the landing page are empty wallet-connect stubs. The specific employee data schema is entirely unknown.
