Pay-per-call employee salary data endpoint on Base via x402 (USDC).
What it does
This x402-enabled endpoint at lowpaymentfee.com returns salary information for a specific employee (ID 61) when called via POST. It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, and utility categories. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint `/api/v1/employees/61/salary` costs $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is made via the x402 `X-PAYMENT` header using the "exact" scheme. The platform advertises no API keys, no rate limits, and instant access — you pay per call and that's it.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned 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 salary response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation means callers must discover the response format experimentally. The endpoint path suggests it returns salary data for employee ID 61, but what dataset this references and what fields are returned is unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it works. However, there is no OpenAPI schema, no request/response examples, no documentation beyond a landing page listing, and the specific purpose of this employee salary endpoint is unclear. The docs pages are all empty ("Connect wallet" only). This is effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, README pages all return only a wallet-connect prompt
- —No OpenAPI or output schema describing the response format
- —Unknown data source — unclear what employee dataset this references or whether it contains real or synthetic data
- —Endpoint is hardcoded to employee ID 61; unclear if other employee IDs are available
