## 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 suverse-base-dex-swap-quote-lifi-aggregator-3f65ffdd -d '<json body>'
```

Example prompt: Get me a swap quote for 500 USDC to WETH on Base mainnet — route through the best available DEX using LiFi aggregation and show me the expected output amount and route.

## When to prefer this

Use this endpoint when you need to swap ERC20 tokens on Base mainnet and want aggregated routing across 20+ DEXs for best price. Ideal for AI agents executing DeFi swaps programmatically with USDC, WETH, AERO, DEGEN, BRETT, TOSHI, cbETH, cbBTC, or any Base ERC20. The two-step quote/execute flow means this is the first step — always follow with the execute endpoint. Prefer this over single-DEX endpoints when best-price routing matters.

## Known failure modes

- Insufficient liquidity for the requested token pair — returns an error with no route found
- Invalid or unsupported token address — returns validation error
- Amount too small to route efficiently — may return no viable route
- Network congestion causing stale quotes — quote may expire before execution
- Malformed request body — returns 400 with schema validation error
- Payment not included or insufficient — returns 402 Payment Required

## Output

Returns a swap quote including the best aggregated route across 20+ Base DEXs (Uniswap V3, Aerodrome, BaseSwap, SushiSwap), expected output token amount, exchange rate, 1% fee breakdown, and transaction calldata needed for the subsequent execute step.
