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 employee salary data for a specific employee (ID 151) 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 each request.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs across categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. However, the specific endpoint being listed here (/api/v1/employees/151/salary) is not documented on the provider's landing page alongside the other advertised APIs. Its exact response schema is unknown; the only confirmed output metadata is that it returns application/json.
The endpoint is live and returns a valid x402 challenge (HTTP 402) with x402Version 1, confirming it is operational. The payment is routed to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using the USDC contract on Base (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The maximum timeout for payment settlement is 300 seconds.

Quality
The endpoint is live and returns a valid x402 challenge, but it is not listed among the provider's documented APIs. There is no OpenAPI schema, no response examples, no request body documentation, and the endpoint path (employees/151/salary) appears to be a demo or test resource. Docs pages returned only 'Connect wallet' with no substantive content.
