Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com returns salary information for a specific employee (ID 66) via a POST request. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and provides instant access — callers simply attach an x402 payment header to authorize each call.
The endpoint is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints on the platform share the same $0.02/request pricing model and x402 payment protocol on Base. However, the specific endpoint being listed here (/api/v1/employees/66/salary) is not documented on the provider's landing page among the advertised API categories, which raises questions about its intended use case and the shape of its response.
No OpenAPI schema, request/response examples, or detailed documentation were found for this endpoint. The docs, API, pricing, and README pages all rendered only a "Connect wallet" prompt with no substantive content. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the lack of documentation means callers must discover the response format empirically.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it accepts payments on Base in USDC at $0.02/request. However, there is no OpenAPI schema, no request/response examples, and no documentation beyond a landing page listing. The specific employee salary endpoint is not even listed among the provider's advertised APIs, making its purpose and output format unclear.
