Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 defillama-dex-summary-ae88686d
```

Example prompt: Pull the DEX summary for Uniswap from DefiLlama — I want the daily volume and the full volume history, but skip the per-chain breakdown.

## When to prefer this

Use this endpoint when you need volume and trading history for a specific decentralized exchange by its protocol slug. Prefer this over the general DEX list endpoints when you already know the protocol name and want detailed volume metrics for a single DEX. Use the optional flags to control whether time-series chart data is included in the response.

## Known failure modes

- Unknown protocol slug returns 404 or empty response
- Invalid dataType parameter may return no data or an error
- Missing required 'protocol' query parameter causes request failure
- Rate limiting or payment failure returns 402 or 429
- DefiLlama upstream data unavailable causes 5xx error

## How this service works

DEX summary by DefiLlama — trading volume and history for one decentralized exchange by protocol slug.

## Output

Returns trading volume metrics for the specified DEX protocol, including aggregate volume time series and optionally a per-chain volume breakdown. Volume data may include dailyVolume, totalVolume, and historical chart data depending on query parameters.
