Pay-per-call employee data endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This x402-enabled endpoint at lowpaymentfee.com serves employee data (specifically employee ID 112) behind a micropayment wall. It uses the x402 "exact" payment scheme on the Base network, accepting USDC (contract 0x8335…2913) with a max amount of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid payment proof.
The endpoint is part of a broader platform (lowpaymentfee.com) that advertises multiple API 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/112) is not explicitly documented on the site's landing page among those categories. It appears to be a standalone or sample resource endpoint returning employee data in JSON format.
Documentation is extremely sparse. The /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee resource contains. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response payload structure is unknown.

Quality
The endpoint is live and returns a valid 402 challenge, confirming x402 protocol support. However, there is no OpenAPI schema, no documented request/response format, no examples, and the specific /employees/112 resource is not mentioned anywhere in the site's own documentation. The docs pages are all empty wallet-connect stubs. This is effectively a stub listing.
