What it does

This endpoint at lowpaymentfee.com provides access to employee salary data via a POST request to `/api/v1/employees/122/salary`. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated by the x402 payment protocol on the Base network.

The endpoint returns a 402 challenge requiring payment in USDC (contract `0x8335...2913` on Base) with a maximum amount of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals). Payment is made via the x402 `exact` scheme with a 300-second timeout. No API keys or rate limits are advertised; access is granted purely through per-call micropayment.

Documentation is extremely sparse. The landing page lists available endpoints and pricing, but the `/docs`, `/api`, `/pricing`, and `/README` routes all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads. The specific endpoint probed (`/employees/122/salary`) is not listed on the homepage among the advertised APIs, which raises questions about whether it is a demo/test route or a production resource. The response MIME type is declared as `application/json`.

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 402 challenge, but documentation is essentially nonexistent — no OpenAPI spec, no request/response schemas, no examples. The specific employee salary endpoint is not listed among the provider's advertised APIs, making its purpose and data source unclear. Score reflects a working payment gate with minimal supporting information.

Warnings

  • No OpenAPI or schema documentation available for this endpoint
  • The /employees/122/salary path is not listed among the provider's advertised APIs on the homepage
  • All documentation pages (/docs, /pricing, /api, /README) render only a 'Connect wallet' prompt with no content
  • Request and response body schemas are completely unknown
  • Data source and accuracy of employee salary information is unverified
