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/12` returns JSON data for employee ID 12 when called with a POST request and a valid X-PAYMENT header containing a USDC micropayment 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, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. Payment is handled entirely via the x402 protocol: no API keys, no accounts, no rate limits. The caller attaches a cryptographic payment proof in the request header, and the server validates it before returning the response.
The x402 challenge confirms the endpoint is live on the Base L2 network, accepting USDC (contract 0x8335…2913) with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). Payments are directed to address 0x1A2B…85F3 with a 300-second timeout. Documentation on the site is extremely thin — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content — so the exact schema of the employee record returned is unknown.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing and network details. However, documentation is essentially absent — docs/pricing/API pages all show only 'Connect wallet'. There is no OpenAPI schema, no example responses, and no description of what fields the employee record contains. The endpoint path itself (/employees/12) is not listed on the homepage's API catalog, making it unclear whether this is a demo or production resource.
Warnings

- —The /api/v1/employees/12 path is not listed among the advertised APIs on the homepage, raising questions about whether this is an official or test endpoint
