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 ID 121) 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 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 protocol's X-PAYMENT header.
This specific endpoint (/api/v1/employees/121) is not listed on the provider's landing page among the advertised API categories, so it may be a demo or internal resource. No OpenAPI schema, detailed documentation, or example responses were found in the crawl. The docs, pricing, and API pages all rendered only a "Connect wallet" prompt with no additional content.
