## 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-defi-intel-swap-quote-f563fc1b
```

Example prompt: What's the best swap quote to convert 1,000,000 USDC (inputMint: EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v) to SOL (outputMint: So11111111111111111111111111111111111111112) with a slippage tolerance of 50 basis points?

## When to prefer this

Use this endpoint when you need a real-time DEX swap quote on Solana with route intelligence and price impact analysis — especially when you want aggregated routing across multiple DEXes (like Orca, Raydium) with a confidence signal, rather than querying a single DEX directly. Ideal for agents that need to evaluate swap feasibility before execution.

## Known failure modes

- Missing required parameters (inputMint, outputMint, amount) returns a 400 error
- Invalid or unrecognized mint addresses return an error or empty route
- No liquidity available for the token pair returns null outAmount or error
- High price impact trades may return a 'high_price_impact' signal warning
- Payment not provided or invalid x402 payment header returns 402 Payment Required
- Service temporarily unavailable returns 5xx error

## How this service works

Crypto-agent toolkit: cross-chain DeFi intelligence + execution helpers + retrieval for agents. 16 endpoints: funding, open interest, long/short, token-safety, yield, prices, gas, tx-simulate, approval-check, bridge-quote, governance-search, lending, liquidations, protocol-search, swap-quote, token-resolve. Pay-per-call via x402.

## Output

Returns a JSON object with the swap route details: inAmount and outAmount in base units, routeLabels showing which DEX(es) are used (e.g. Orca), priceImpactPct as a percentage, a signal string (e.g. 'low_price_impact'), a human-readable insight string, confidence score (0–1), and sources array indicating which aggregators were queried.
