Pay-per-call employee data API on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record #49) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 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/49) is not documented on the provider's landing page among the advertised APIs. Its exact response schema is unknown — the x402 challenge confirms it returns application/json but no output field schema is provided.
The endpoint is live and returns a proper 402 challenge. The provider's root page loads successfully (HTTP 200). Documentation pages (/docs, /pricing, /api, /README) all appear to require wallet connection and contain no readable content, so details about the employee data structure, available fields, or query parameters remain unclear.

Quality
The endpoint is live and returns a valid x402 402 challenge, but the specific /api/v1/employees/49 path is not listed among the provider's advertised APIs. No OpenAPI schema, no response examples, and all documentation pages are gated behind wallet connection, yielding no useful content. The response structure is entirely unknown.
