## When to prefer this

Choose this endpoint when you need a quick, per-call crypto-to-crypto conversion with no account setup, paid per use via USDC on Base. Ideal for AI agents needing lightweight, on-demand conversion math without maintaining API keys or subscriptions. Prefer over full exchange APIs when only a simple rate lookup and amount conversion is needed.

## Known failure modes

- Missing required query parameters (from, to, or amount) may result in a 400 error
- Payment not settled via x402 results in 402 Payment Required
- Network or upstream price feed unavailability causes 500 error
- Stale or delayed price data may cause slight inaccuracies in result
