## When to prefer this

Use this endpoint when you need a quick, no-account, pay-per-call USD price for the Uniswap (UNI) token without setting up API keys or subscriptions. It is ideal for lightweight agents that need spot crypto prices on demand and can pay micro-amounts in USDC over Base via x402. Prefer this over heavier data providers when cost per call and simplicity matter more than historical data or batch queries.

## Known failure modes

- Price feed unavailable or stale — may return an error or outdated price
- Invalid or missing query parameters — returns 400 Bad Request
- Upstream on-chain RPC failure — may return 503 or partial data
