Pay-per-call employee data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data records via the x402 payment protocol. The specific resource `/api/v1/employees/10` returns JSON data for employee ID 10 when called with a POST request and a valid X-PAYMENT header containing a USDC payment on the Base network.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers numerous pay-per-call APIs spanning data & analytics, AI & machine learning (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints on the platform are priced at $0.02 per request, paid in USDC on the Base L2 network. The x402 challenge confirms the asset address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 (Base USDC) with a maxAmountRequired of 20000 base units, which equals $0.02 (20000 / 10^6).
The platform advertises no API keys, no rate limits, and instant access. Documentation pages exist at /docs, /pricing, and /api but currently render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no example request/response documentation, and no detail on what fields the employee record contains. The endpoint is live and returning a proper 402 challenge.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no documented request/response format, no example payloads, and the docs/pricing/API pages are empty stubs showing only 'Connect wallet'. The actual data returned by the employee endpoint is completely unknown.
Warnings
- —No OpenAPI or JSON schema available for request or response bodies
- —Documentation pages (/docs, /pricing, /api, /README) are empty — only show 'Connect wallet'
- —No information on what fields the employee record contains or what input the POST body expects
- —The endpoint path suggests sample/demo data (employee ID 10) — unclear if this is production data
