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 #81) 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 broad catalog of pay-per-call APIs spanning 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). 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 protocol's X-PAYMENT header.
This specific endpoint (/api/v1/employees/81) is not listed on the provider's landing page among the advertised API categories, so its exact response schema and data source are unclear. The 402 challenge confirms it is live and accepting payment, but no documentation, OpenAPI spec, or example responses were found for this particular resource. The endpoint's description in the x402 challenge is simply "Premium API Access," which is generic and does not clarify the data returned.
