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 (specifically employee record #9) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).
The provider lowpaymentfee.com hosts a broader suite of pay-per-call APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are priced uniformly at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payments are made inline via the x402 X-PAYMENT header on the Base L2 network.
This specific endpoint (/api/v1/employees/9) appears to be a sample or demonstration resource — it is not listed among the provider's advertised API categories on the landing page. Documentation pages (/docs, /pricing, /README) returned only a "Connect wallet" prompt with no substantive content, so the exact schema of the employee record returned is unknown. The endpoint is confirmed live (402 challenge captured successfully).
