Pay-per-call employee data API on Base via x402 — $0.02/request in USDC.
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/111` returns JSON data for employee ID 111 when called with a valid x402 payment header. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The endpoint is part of a broader platform (lowpaymentfee.com) that offers multiple API categories including data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access; payment is the only authentication mechanism. The x402 challenge confirms 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 request/response examples, and no description of what fields the employee record contains. The endpoint path suggests a REST-style resource for retrieving or interacting with employee records, but the exact input parameters and output shape are unknown.
