## 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-dexter-cash-74a02b08
```

Example prompt: Give me a Jupiter swap quote on Dexter for trading 5 SOL to USDC — I want to see the expected output amount and price impact before I execute anything.

## When to prefer this

Use this endpoint when you need a pre-execution swap quote from the Jupiter aggregator on Solana, specifically to preview expected output, price impact, and routing before committing to a trade. Prefer this over the Pro-tier sibling endpoint for standard-volume trades. Best suited for agents building Solana DeFi workflows that need quote data without executing the swap.

## Known failure modes

- Invalid token mint address returns an error
- Trade amount too small or too large may return no valid route
- Token pair with insufficient liquidity may return high price impact warning or no route
- Network congestion may cause stale or unavailable quotes
- Missing required parameters (input token, output token, amount) returns 400 error
- Payment not completed ($0.05 USDC via x402) returns 402 Payment Required
