```sh
zero fetch --capability agenticfi-bridge-quote-4a205a66
```

Example prompt: Get me a bridge quote to move 0.001 ETH (that's 1000000000000000 in wei) from Base (chain 8453) using token 0x4200000000000000000000000000000000000006 to USDC on Ethereum mainnet (chain 1, token 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) from my wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e.

## When to prefer this

Use this endpoint when an agent needs to estimate how many tokens a user will receive after bridging from one EVM chain to another before executing the actual transfer. Ideal for pre-flight checks, UI quote displays, or route comparison in multi-step cross-chain DeFi workflows.

## Known failure modes

- Invalid chain ID returns 400 error — chain must be a supported EVM chain ID such as 1, 8453, or 42161
- Invalid token address returns 400 — must be a valid EVM contract address
- fromAmount must be in smallest unit (wei/raw decimals); human-readable amounts will cause incorrect quotes or errors
- Unsupported token pair on the specified chain combination returns no routes found
- Sender address not a valid Ethereum address returns 400
- Network unavailability or bridge provider outage returns 503 or timeout

## How this service works

## Output

Returns a bridge quote including estimated output token amount, route details, fees, and bridge provider information for a cross-chain token transfer.
