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 140) behind a micropayment wall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum charge of 20,000 base units (i.e., $0.02 per request, since USDC uses 6 decimals).
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. The platform emphasizes no API keys, no rate limits, and instant access. However, the specific endpoint being listed here (/api/v1/employees/140) is not explicitly documented on the landing page among the advertised APIs, and no detailed documentation, request/response schemas, or example payloads are available from the crawled pages (docs, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content).
Because there is no OpenAPI spec, no response schema, and no documentation beyond the landing page overview, the actual data returned by this endpoint is unknown. The endpoint is confirmed live (returns a proper 402 x402 challenge), but what "employee 140" data looks like remains unspecified.

Quality
The endpoint is confirmed live with a valid 402 x402 challenge, but there is no OpenAPI spec, no response schema, no example payloads, and no meaningful documentation. The /api/v1/employees/140 path is not listed among the site's advertised APIs, making its purpose and output unclear. Effectively a stub listing.
