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/21` returns JSON data for employee ID 21 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 dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request. The x402 challenge confirms the price: maxAmountRequired of 20,000 base units of USDC (6 decimals) equals $0.02. Payment is sent to address 0x1A2B...85F3 on Base, using the USDC contract at 0x8335...2913. No API keys or rate limits are advertised; access is gated purely by micropayment.
Documentation is extremely thin — 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 responses. The endpoint is confirmed live (returns a proper 402 challenge), but the actual shape of the response data after payment is unknown.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no documentation of request/response formats, no example payloads, and the docs pages are empty. The actual data returned after payment is completely unknown, making this effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content
- —The employee data model and available fields are not documented anywhere
- —No example responses available; the actual utility of the data cannot be verified without paying
