Get the current UNI token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the UNI (Uniswap) token. It is part of a broader suite of pay-per-request APIs hosted at lowpaymentfee.com, covering finance, crypto, AI, analytics, and utility services. Payment is handled via the x402 protocol on the Base network using USDC, with no API keys, rate limits, or subscriptions required.
The specific endpoint `/api/v1/tokens/UNI/price` accepts POST requests and charges 0.02 USDC per call (20,000 base units of USDC with 6 decimals). The x402 challenge confirms the endpoint is live and settles payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base. The response MIME type is `application/json`.
Documentation beyond the landing page is minimal — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example responses, and no schema describing the returned price object. The endpoint appears functional based on the 402 challenge, but the exact response format must be inferred.
