Pay-per-call employee data API on Base, settled in USDC via x402 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/148` returns JSON data for employee ID 148 when called with a valid x402 payment header. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The provider lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. The x402 challenge was successfully captured, confirming the endpoint is live and accepting POST requests.
Documentation is extremely sparse. The docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no description of the employee data model, and no example request/response payloads available. The exact fields returned for an employee record are unknown and must be discovered by making a paid request.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing and network details. However, documentation is essentially nonexistent — no OpenAPI schema, no example payloads, no description of the data model. The employee data endpoint is not listed on the provider's landing page (which lists analytics, AI, finance, and utility APIs but not employee endpoints), raising questions about its purpose and data content.
