## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability halowerk-defiwerk-bridge-quote-cc4c6ad1 -d '<json body>'
```

Example prompt: Get me a bridge quote to move 500 USDC (contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) from Ethereum to Base — how much will I receive and what are the fees?

## When to prefer this

Use this endpoint when you need a real-time, paid cross-chain bridge quote between EVM-compatible chains and want per-call micropayment pricing via x402/USDC rather than API-key subscriptions. Prefer it for agents operating autonomously on Base Mainnet that need bridge cost estimation before executing a transfer.

## Known failure modes

- Unsupported chain pair returns an error indicating no route available
- Invalid token contract address (not 0x + 40 hex chars) returns a validation error
- Amount of zero or negative value may return an error or empty quote
- Token not supported on destination chain returns no-route error
- Network congestion or bridge provider downtime may cause timeout or empty response
- Missing required fields (token, amount, to_chain, from_chain) returns a 400-level error

## Output

Returns a bridge quote object containing the estimated output token amount on the destination chain, applicable bridge fees, the bridge protocol or route selected, exchange rate, and any slippage estimates. Used to evaluate cost and feasibility before executing an actual cross-chain transfer.
