## 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 x402-chain-intel-bridge-fees-531d98cd -d '<json body>'
```

Example prompt: What are the current bridge fees to move 1000 USDC from Ethereum mainnet to Arbitrum One? I want to know the total cost before my trading bot executes the transfer.

## When to prefer this

Choose this endpoint when your trading bot or DeFi automation needs real-time bridge fee data before executing a cross-chain transfer, especially when optimizing for cost across multiple bridge protocols. Prefer this over manually querying each bridge's UI when you need fee data programmatically at scale.

## Known failure modes

- Unsupported chain pair returns an error or empty result
- Invalid token address causes a 400 bad request
- Bridge protocol temporarily unavailable returns 503 or null fees
- Stale fee data if on-chain conditions change rapidly
- Payment of 0.09 USDC required per call — missing payment header returns 402
