## 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 arcgate-swap-quote-f5ef9eea -d '<json body>'
```

Example prompt: Get me a swap quote to buy exactly 500 USDC by selling WETH — use exactOut side, allow up to 2 hops and splits across venues, with 30 basis points slippage and a 60-second TTL.

## When to prefer this

Use this endpoint when you need a real-time, multi-venue DEX swap quote with fine-grained control over routing (hops, splits, venue inclusion/exclusion) before committing to a transaction. Prefer this over generic price-feed APIs when you need an actionable, executable quote — especially when paired with ArcGate's swap transaction endpoint to complete the trade. Best suited for DeFi agents that need to evaluate trade feasibility and cost before execution.

## Known failure modes

- Invalid or unknown token symbols in buy/sell fields
- Amount too small or too large for available liquidity
- No route found between the specified tokens
- Unsupported or unavailable venue specified
- TTL value outside 1–120 range
- Slippage bps outside 0–5000 range
- maxSplits or maxHops out of allowed range
- Payment not provided or incorrect (x402 payment required)
