Pay-per-call employee salary data endpoint on Base via x402 (USDC).
What it does
This x402-enabled endpoint at lowpaymentfee.com returns employee salary data for a specific employee (ID 80) via a POST request. It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning 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/80/salary` costs $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is handled via the x402 `X-PAYMENT` header with the "exact" scheme. The provider advertises no API keys, no rate limits, and instant access. The x402 challenge was successfully captured, confirming the endpoint is live.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary response contains. The endpoint path suggests it returns salary information for employee ID 80, but the actual response structure is unknown. The provider's landing page lists this endpoint's category and pricing but provides no further technical detail.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty beyond a wallet-connect prompt. The endpoint's actual response structure is entirely unknown, making this effectively a stub listing.
Warnings
- —No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
- —No OpenAPI or response schema provided; response structure is unknown
- —Endpoint is hardcoded to employee ID 80 — unclear if other IDs are supported or if this is a demo
- —No robots.txt or agents.txt present
- —Provider appears to be a demo/showcase site for x402 protocol rather than a production data source
