x402-gated employee data endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com serves employee data behind an x402 payment wall. The specific resource `/api/v1/employees/71` returns JSON data for employee record #71 when a valid X-PAYMENT header is provided. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this translates to $0.02 per call — consistent with the provider's advertised flat pricing of $0.02/request across all their APIs. The provider advertises no API keys, no rate limits, and instant access. The x402 challenge was successfully captured with a 402 response, confirming the endpoint is live.
The broader lowpaymentfee.com platform offers multiple API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all at the same $0.02/request price point. However, this specific listing is for the employees endpoint, which is not prominently featured on the provider's landing page. No OpenAPI schema, detailed documentation, or example responses were available in the crawled material; the docs, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no response examples, no documentation beyond a wallet-connect prompt, and the /employees/ path is not listed on the provider's own landing page, making the actual data content and schema unknown.
Warnings
- —The /api/v1/employees/71 endpoint is not listed among the provider's advertised APIs on the landing page — its data content is unverified.
- —No documentation, OpenAPI spec, or example responses are available; docs/pricing/README pages all render only 'Connect wallet'.
- —Response schema is completely unknown — callers cannot predict the shape of returned data.
