## 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 m2m-sentinel-dex-liquidity-and-volume-metrics-8262a75d
```

Example prompt: Pull the latest DEX liquidity and trading volume observations from M2M Sentinel for the tracked Base tokens right now.

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity depth and trading volume data specifically for tokens on the Base blockchain, and you want pre-observed, structured metrics rather than querying a DEX contract directly. Prefer this over raw on-chain calls when you need fast, aggregated observations with provenance from a dedicated sentinel service.

## Known failure modes

- Token not tracked — endpoint only returns data for tokens in M2M Sentinel's tracked set
- No recent observations available — liquidity data may be stale or unavailable for low-activity tokens
- Payment failure — x402 payment of $0.01 USDC not completed, request rejected
- Rate limiting — too many requests in a short window
- Network or provider downtime — Base chain data temporarily unavailable

## How this service works

How deep is liquidity for tracked Base tokens and how much is actually trading, with the source named, for sizing an order or declining one.

## Output

Returns an array or object of DEX metrics for tracked Base tokens, including liquidity and volume observations, with a SUCCESS status indicating the data was retrieved successfully.
