## 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 gateway-spraay-app-0e3a40cb
```

Example prompt: How much USDC would I get if I swapped 1 ETH (0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2) to USDC (0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) right now on Uniswap V3?

## When to prefer this

Use this endpoint when you need an EVM/Ethereum Uniswap V3 swap quote specifically; prefer the sibling Jupiter endpoint for Solana-native swaps. Best for agents that need to price ERC-20 token swaps before executing a trade or displaying exchange rates to users.

## Known failure modes

- Invalid token addresses return an error or empty result
- Unsupported token pair with no Uniswap V3 pool returns no route found
- amountIn of zero or malformed string may cause a validation error
- Payment failure (402) if x402 payment header is missing or insufficient
- Network congestion or RPC issues may cause timeout or stale pricing
