```

Example prompt: Convert 250 EUR to USD for me and tell me the current exchange rate.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call currency conversion with no subscription required, particularly when already operating within the x402 USDC micropayment ecosystem on Base or Solana. Ideal for agents that need occasional FX conversions without committing to a dedicated forex API subscription.

## Known failure modes

- Invalid or unsupported currency code returns an error
- Missing required 'from' or 'to' parameters results in a 400-level error
- Payment failure or insufficient USDC balance blocks the request with a 402 Payment Required response
- Network or upstream exchange rate provider outage may result in 5xx errors or stale data
