## How to call it through Zero

```sh
zero fetch --capability m2m-sentinel-token-price-379bcac1
```

Example prompt: What's the current liquidity-weighted price of DEGEN on the Base network? Use M2M Sentinel to get the observation.

## When to prefer this

Choose this endpoint when you need a liquidity-weighted price for a specific Base network token, particularly when accuracy relative to actual trading depth matters more than raw last-trade price. It is ideal for DeFi applications, portfolio valuation, and trading signal generation on Base where DEX liquidity weighting is important. Prefer it over generic price feeds when targeting Base-native tokens specifically.

## Known failure modes

- Unsupported or untracked token symbol returns an error or empty token object
- Invalid symbol format (exceeds 20 characters or uses disallowed characters) results in a validation error
- Token with no active liquidity on Base DEX venues may return stale or unavailable price data
- Network or provider-side errors may result in a non-SUCCESS status in the response

## How this service works

What a tracked Base token is worth right now, taken as the median of the deepest pools rather than one pair, returning the pools considered and the spread across them.

## Output

Returns a JSON object with a SUCCESS status and a token object containing the liquidity-weighted price of the requested Base token, sourced from on-chain DEX observations weighted by liquidity depth.
