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 90) 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 platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs across categories including 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/90/salary`) is not prominently documented on the provider's landing page, which focuses on analytics, AI, finance, and utility endpoints. No OpenAPI schema, request body format, or response examples are provided in the available documentation.
The endpoint is live and returns a valid x402 challenge (HTTP 402) with version 1 of the protocol. The payment is routed to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, using the USDC contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`. The maximum timeout for payment settlement is 300 seconds.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no documented request/response format, and the specific employee salary endpoint is not listed on the provider's own landing page. The actual data returned is unknown, making this effectively a stub listing.
