x402-payable employee salary lookup endpoint on Base, settled in USDC per request.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via the x402 payment protocol. The specific resource `/api/v1/employees/184/salary` returns salary information for employee ID 184 when called with a POST request and a valid x402 payment header. Payment is settled in USDC on the Base network.
The endpoint charges a maximum of 20,000 base units of USDC (0.02 USD) per request, consistent with the provider's site-wide flat pricing of $0.02/request across all their API offerings. The provider advertises no API keys, no rate limits, and instant access — payment is the only authentication mechanism. The x402 challenge uses the "exact" scheme with a 300-second timeout.
The broader lowpaymentfee.com platform hosts multiple API categories including data/analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). However, this specific endpoint — employee salary data — is not listed on the provider's public landing page, which raises questions about its intended use case and whether it returns real or sample data. No OpenAPI schema, request/response examples, or detailed documentation were found during the crawl.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, no documentation beyond a near-empty docs page, and this specific employee salary endpoint is not listed on the provider's own landing page. The nature and authenticity of the data returned is unknown.
