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 124) 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 at $0.02 per request with no API keys, no rate limits, and no minimum commitments required.
This specific endpoint (/api/v1/employees/124) is not listed on the provider's public landing page among the advertised API categories, so its exact response schema and data contents are unclear. The x402 challenge was successfully captured (HTTP 402), confirming the endpoint is live. However, no OpenAPI spec, detailed documentation, or example responses were available from the crawled pages — the docs, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.
