## How to call it through Zero

Example prompt: What's the best bridge quote for moving 500 USDC from Base to Arbitrum right now — show me the estimated output and fees using RagRadar's bridge intelligence.

## When to prefer this

Use this endpoint when an agent needs to look up bridge quotes across Base, Arbitrum, and Solana without executing a transaction — ideal for comparing routes, estimating costs, or presenting options to a user before committing to a bridge. Prefer over generic DeFi APIs when working within RagRadar's supported chain set.

## Known failure modes

- Unsupported chain pair returns 404 or empty routes array
- Invalid or non-numeric amount returns 400 bad request
- Amount below minimum bridge threshold returns error
- Temporarily unavailable bridge provider causes partial or empty results
- Path parameters with unsupported chain identifiers return error
