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/102` returns JSON data for employee ID 102 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 numerous pay-per-call APIs spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. Payment is handled entirely on-chain via x402: no API keys, no accounts, no rate limits. The x402 challenge confirms the endpoint is live, accepting USDC (contract 0x8335…2913) on Base with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals).
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint's actual data shape (what fields an employee record contains) is unknown from the crawled material. The listing title "Premium API Access" is generic and does not describe the specific resource.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The actual data returned is entirely unknown.
