x402-gated employee salary lookup endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via a POST request to `/api/v1/employees/120/salary`. It is part of a broader platform (lowpaymentfee.com) that offers dozens of x402-payable API endpoints spanning data analytics, AI/ML inference, finance, and utility services.
The endpoint is live and returns a standard x402 payment challenge. It accepts payment on the Base network using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) with the "exact" payment scheme. The maximum amount required is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a timeout of 300 seconds.
The platform advertises a flat $0.02 per request across all its endpoints, with no API keys, no rate limits, and instant access. However, documentation pages (docs, pricing, README) all resolve to minimal "Connect wallet" stubs, so there is no detailed schema documentation for request bodies or response formats for this specific employee salary endpoint. The exact data returned and the meaning of the employee ID path parameter (here `120`) are not documented in the crawled material.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no examples, and all documentation pages are empty stubs. The purpose of the endpoint (employee salary data) is only inferable from the URL path.
Warnings
- —No API documentation available — docs, pricing, and README pages all show only 'Connect wallet' with no content.
- —Request body schema and response format are completely undocumented.
- —The nature of the 'employee salary' data is unclear — it may be demo/mock data rather than a real data source.
- —No information on data provenance, accuracy, or update frequency.
