## How to call it through Zero

```sh
zero fetch --capability ragradar-bridge-quote-lookup-f84728df
```

Example prompt: What's the bridge quote for moving 500 USDC from Base to Arbitrum right now — how much will I get on the other side and what are the fees?

## When to prefer this

Use this endpoint when you need real-time cross-chain bridge quotes across Base, Arbitrum, or Solana before executing a token transfer. Ideal for DeFi agents that need to compare bridge costs, estimate output amounts, or decide optimal routing before committing to a transaction. Prefer this over general DEX quote endpoints when the intent is cross-chain rather than same-chain swap.

## Known failure modes

- Unsupported 'from' or 'to' token/chain pair returns a 404 or error response
- Invalid or non-numeric amount returns a 400 bad request
- Quote unavailable due to liquidity issues or bridge downtime returns an error
- Backup domain may have higher latency or occasional outages
- Missing path parameters causes routing failure

## How this service works

On-chain intelligence for AI agents. 73+ endpoints across Base, Arbitrum, Solana. x402 micropayments.

## Output

Returns a bridge quote object including the estimated output amount, exchange rate, fees, and route details for transferring a specified token amount from one chain/token to another.
