## 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 ez-path-dex-aggregator-quote-5548d456
```

Example prompt: What's the best price I can get for swapping 1000000000000000000 wei of WETH into USDC right now — check across all the major DEXes and give me the highest buyAmount.

## When to prefer this

Choose this endpoint when you need to find the best possible swap rate for an ERC-20 token pair without executing a trade — especially when you want a single call that fans out to 10 major DEX venues (including CoW, Curve, Aerodrome, and Synthetix) rather than querying each separately. Prefer it over single-venue quotes whenever maximizing buyAmount matters.

## Known failure modes

- Missing required query params (sellToken, buyToken, sellAmount) returns 400
- Invalid token addresses return an error or empty result
- Illiquid pair with no quotes available across all 10 venues
- Payment not provided or insufficient (x402 payment required at $0.03 USDC per call)
- Network congestion or venue API timeouts may delay or degrade results

## How this service works

EZ-Path DEX Quote — races 10 venues (0x, ParaSwap, Aerodrome, Uniswap V3, Curve, Balancer, Uniswap V2, 1Inch, CoW, Synthetix) and returns the highest buyAmount

## Output

Returns the best swap quote found across 10 DEX venues, including buyAmount, sellAmount, price ratio, estimatedGas, and a breakdown of which liquidity sources (and their proportions) contributed to the route.
