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/40` returns JSON data for employee ID 40 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 (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints on the platform are priced at $0.02 per request, paid in USDC on Base, with no API keys, no rate limits, and no minimum commitments required.
The x402 challenge confirms the endpoint is live, accepting payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on the Base network. The maxAmountRequired of 20000 base units (USDC has 6 decimals) equals $0.02 per call. The response MIME type is application/json. Documentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documented request/response format, no example payloads, and all documentation pages beyond the landing page are empty stubs. The specific purpose and schema of the /employees/40 resource is entirely undocumented.
Warnings
- —No API documentation available — docs, pricing, and README pages all render only a wallet-connect prompt with no technical content.
- —No request or response schema is documented for the /api/v1/employees/{id} endpoint.
- —The nature and source of the 'employee' data is unknown — it may be sample/demo data rather than a production dataset.
- —Output schema in the x402 challenge only specifies HTTP POST method; no field-level schema is provided.
