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 an employee record (ID 39) via a POST request, gated by the x402 payment protocol. Each call costs $0.02 in USDC on the Base network. No API keys, rate limits, or subscriptions are required — callers simply attach an x402 payment header to authorize each request.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. The specific endpoint `/api/v1/employees/39` returns JSON (MIME type application/json) and appears to serve structured employee data, though the exact response schema is not documented.
The x402 challenge confirms the endpoint is live, accepting payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` in USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base. The maximum amount required is 20,000 base units (i.e., $0.02 given USDC's 6 decimals). Payment timeout is 300 seconds. Documentation beyond the landing page is essentially empty (all sub-pages just show "Connect wallet"), so the response format must be inferred.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documented response format, and all documentation pages are empty stubs. The specific purpose of the /employees/39 endpoint is only inferable from its URL path. This is effectively a stub listing.
Warnings
- —No API documentation available — all doc pages return only 'Connect wallet'
- —Response schema for /api/v1/employees/39 is completely undocumented
- —The endpoint serves a single hardcoded employee ID (39); unclear if other IDs are supported
- —No examples of actual response payloads found in crawl material
