## How to call it through Zero

```sh
zero fetch --capability api-carbon-cashmere-de-a3de0105
```

Example prompt: Show me the top DEX liquidity pools for ETH on Ethereum with at least $50,000 in liquidity — I want to see the pair addresses, volumes, and FDV from DexScreener snapshots, filtered to trusted chains only.

## When to prefer this

Use this endpoint when you need multi-chain DEX pool data for a specific coin ranked by liquidity, especially when you need to distinguish canonical token pools from memecoin variants using trusted-chain and trusted-quote flags. Prefer over raw DexScreener API when you want a pre-filtered, snapshot-based view with chain trust metadata already applied.

## Known failure modes

- Unknown or unsupported coin ticker returns an empty pools array
- Coin ticker matches memecoin variants on untrusted chains — use trusted_chain + trusted_quote flags to filter
- min_liquidity_usd too high may return zero pools
- DexScreener snapshot may be up to 10 minutes stale
- Chain parameter misspelled returns no filtered results
- Base address not validated — price may not reflect canonical wrapped token

## How this service works

Latest DexScreener DEX pool snapshots per coin across all chains. Top pools by liquidity with chain_id, dex_id, pair_address, volume, FDV, market_cap. Trusted-chain flags filter canonical-token pools vs memecoin variants. Informational only.

## Output

A list of DEX pool snapshots for the requested coin, each with chain_id, dex_id, pair_address, volume, FDV, market_cap, and trusted_chain/trusted_quote boolean flags. Includes aggregate stats (trusted_pools count, pools_returned, trusted_chain_pools, trusted_quote_pools) and metadata warnings about ticker reuse across chains.
