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 record #78) behind a micropayment wall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with an exact-scheme x402 challenge. The maximum amount required per call is 20,000 base units of USDC, which at 6 decimals equals $0.02 USD.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. However, the specific `/api/v1/employees/78` path is not listed among the publicly advertised endpoints on the landing page, so its exact response schema and data contents are unclear.
Documentation is extremely sparse: the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response, and no description of what fields the employee record contains. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the lack of documentation makes it difficult to know what data you'll receive after payment.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documentation beyond a wallet-connect prompt, no example request/response, and the specific /employees/78 path isn't even listed on the site's own landing page. The data contents are entirely unknown.
Warnings
- —The /api/v1/employees/78 path is not listed among the provider's publicly advertised endpoints — its purpose and data schema are unknown.
- —All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no technical content.
- —No OpenAPI spec or response schema available; the structure of the returned employee data is undocumented.
- —The endpoint serves a single hardcoded record (#78); it is unclear if other employee IDs are available or what parameterization is supported.
