## When to prefer this

Use this endpoint when you need a real-time cross-chain bridge quote before executing a transfer, especially when working with EVM-compatible chains and want fee and route details without committing to a transaction.

## Known failure modes

- Unsupported chain pair returns error or empty route
- Invalid or missing fromAddress returns validation error
- Amount too small or too large for the bridge returns rejection
- Token not supported on one or both chains returns error
- Network congestion may cause stale or unavailable quotes

## How this service works

## Output
