## 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 lenscrypt-bridge-quote-cross-chain-swap-price-lookup-cc899892

Example prompt: What's the bridge quote for swapping 500 USDC to ETH right now — can you check the LensCrypt bridge quotes endpoint for that pair and amount?

## When to prefer this

Use this endpoint when you need a real-time cross-chain bridge or DEX swap quote between two specific tokens for a given amount. Prefer this over general price endpoints when you specifically want bridging route cost estimates including fees and slippage, not just raw market prices.

## Known failure modes

- Invalid or unsupported token symbol in 'from' or 'to' path param — returns 400 or empty result
- Amount not parseable or zero — returns 400 bad request
- Token pair has no available liquidity route — returns 404 or empty quotes array
- Payment not processed (x402 payment required) — returns 402 Payment Required
- Upstream bridge/DEX provider timeout — returns 503 or partial data
