## 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 base-dex-trending-pools-9e20221b
```

Example prompt: Show me the top 5 trending DEX pools on Base right now, looking back over the last 30 minutes — I want to see which ones have the highest swap volume and whether there's more buying or selling pressure.

## When to prefer this

Use this endpoint when you need a real-time, ranked snapshot of which Base L2 DEX pools are most actively traded and whether buy or sell pressure dominates — especially for DeFi trading signals, market monitoring, or identifying hot tokens on Base. Prefer over generic CEX volume APIs when on-chain DEX-specific flow data (Aerodrome, Uniswap V3 on Base) is required.

## Known failure modes

- Invalid window format (e.g. unsupported duration string) returns 400 error
- limit out of range (must be 1-6) returns 400 validation error
- No pools found within the window returns empty result set
- On-chain RPC unavailability causes 503 or timeout
- Stale data if recent blocks have not been indexed yet

## How this service works

Trending Base DEX pools ranked by recent swap volume and net buy/sell flow over a short window, computed by us from public Aerodrome/Uniswap-V3 Swap event logs.

## Output

A ranked list of Base DEX pools (up to the requested limit) sorted by recent swap volume, each including pool identifiers, trading pair, swap volume over the lookback window, and net buy/sell flow computed from Aerodrome and Uniswap-V3 Swap event logs on Base L2.
