## How to call it through Zero

```sh
zero fetch --capability x402-silverbackdefi-app-f0efd7ac
```

Example prompt: What's the best Jupiter quote for swapping 1 SOL (So11111111111111111111111111111111111111112) to USDC (EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v) right now, with a slippage tolerance of 0.5%?

## When to prefer this

Use this endpoint when you need real-time swap quotes specifically on the Solana blockchain via Jupiter aggregator, which aggregates routes across all major Solana DEXes for optimal pricing. Prefer this over single-DEX price checks when you want the best available route and price impact estimate before executing a swap.

## Known failure modes

- Invalid or unrecognized token mint address returns an error
- Amount set to zero or missing causes a validation failure
- Unsupported token pair with no available liquidity route returns no-route error
- Network congestion on Solana may cause delayed or stale quotes
- Slippage set too low may result in no viable route being returned

## How this service works

Get a swap quote from Jupiter aggregator for Solana tokens. Returns optimal route, price impact, and fees.

## Output

Returns a success flag and a data object containing the optimal swap route across Solana DEXes, estimated output amount, price impact percentage, and fee breakdown for the requested token pair and input amount.
