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 67) 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 priced at $0.02 per request. However, the specific endpoint being listed here (`/api/v1/employees/67/salary`) is not prominently featured on the provider's landing page among the advertised API categories. It appears to be a demo or sample resource. No OpenAPI schema, request body documentation, or response examples are available from the crawled material.
The endpoint is confirmed live: it returns a proper x402 version 1 challenge with a 402 status code, advertising payment to address `0x1A2B...85F3` using USDC on Base. The maximum amount required is 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The payment timeout is 300 seconds.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, but there is no OpenAPI schema, no documented request/response format, no examples, and the specific employee salary endpoint is not listed among the provider's advertised APIs. The crawled docs/pricing/README pages returned only 'Connect wallet' with no substantive content.
