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 (specifically employee record #119) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 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 at $0.02 per request. This specific endpoint falls under what appears to be a sample or demonstration resource (employees/119). No API keys or rate limits are advertised; callers simply attach an x402 payment header to each request.
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 or what POST body parameters are accepted. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data contract is unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no request/response examples, no documentation beyond a wallet-connect prompt, and the purpose of the employee data endpoint is unclear. Effectively a stub listing.
