Pay-per-call employee data API on Base, settled in USDC via x402 at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record #63) via the x402 payment protocol. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The broader lowpaymentfee.com platform advertises a wide 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 listed at the same $0.02/request price point. However, the specific endpoint being listed here — `/api/v1/employees/63` — is not documented on the site's landing page, and no schema or example response is provided for it. The exact shape of the returned employee data is unknown.
The x402 challenge was successfully captured (HTTP 402 with valid accepts array), confirming the endpoint is live. The payment address is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base mainnet. The maximum timeout for payment settlement is 300 seconds.
