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/55` returns JSON data for employee ID 55 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. The x402 challenge confirms the price: maxAmountRequired of 20,000 base units of USDC (6 decimals) equals $0.02. Payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on the Base L2 network using the USDC contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee record contains. The endpoint is confirmed live (returns 402 with a well-formed x402 challenge), but the actual data returned after payment is unknown. The platform advertises no API keys, no rate limits, and instant access.

Quality
The endpoint is confirmed live with a valid x402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation of request parameters or response fields, and no examples of actual responses. The docs pages are empty beyond a wallet-connect prompt. The specific endpoint (/employees/55) is not listed on the homepage, making its purpose and data format entirely opaque.

- —No OpenAPI or response schema provided; response structure after payment is unknown
- —The /api/v1/employees/55 endpoint is not listed among the advertised APIs on the homepage
