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/85` returns JSON data for employee ID 85 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 made in USDC (contract 0x8335…2913) on Base L2, using the x402 "exact" scheme. There are no API keys, no rate limits, and no subscription commitments; each call is individually settled on-chain.
The specific data returned by this employees endpoint is not documented. The crawled site pages (docs, pricing, README) all resolve to a minimal "Connect wallet" prompt with no further documentation. The employee resource path suggests a sample or demo dataset rather than a production HR system, but this cannot be confirmed from available material. The x402 challenge is live and well-formed, with a max amount of 20,000 base units (i.e., $0.02 USDC given 6 decimals) and a 300-second payment timeout.

Quality
The x402 challenge is live and well-formed, confirming the endpoint is operational. However, there is no OpenAPI schema, no response examples, no documentation beyond a wallet-connect prompt, and the nature of the employee data returned is entirely unknown. This is effectively a stub listing.

- —Response schema and fields for /api/v1/employees/85 are completely undocumented
- —The employee data endpoint may be a demo/sample dataset; no indication of real production data
- —No OpenAPI spec or example responses available
