Pay-per-call employee data API on Base, settled in USDC via x402 at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record #53) via a pay-per-request x402 payment model. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an x402 payment header to each request.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers multiple API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per call. However, this specific listing covers the `/api/v1/employees/53` resource, which appears to be an employee data endpoint. The exact schema of the employee record returned is not documented in the available crawl material, so the response structure must be discovered by making a paid request.
The x402 challenge was successfully captured with version 1 of the protocol, confirming the endpoint is live. The payment address is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, the USDC asset contract is `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base, and the maximum timeout is 300 seconds.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documented request/response format for the employees endpoint, and the crawled docs/pricing/README pages all returned only 'Connect wallet' with no useful content. The endpoint's actual data payload is unknown.
