## 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 coingecko-924116a6
```

Example prompt: What's the current onchain price and 24-hour trading volume for the token at contract address 0x1234abcd...ef on the Monad network? Also include the market cap if available.

## When to prefer this

Use this endpoint when you need real-time onchain DEX price data specifically for a token deployed on the Monad network and you have its contract address. Prefer this over CoinGecko's standard token price endpoints when you need DEX-sourced (not CEX-aggregated) pricing or when the token is only traded onchain on Monad.

## Known failure modes

- Invalid or unrecognized contract address returns 404 or empty result
- Token not listed on any Monad DEX returns no price data
- Network temporarily unavailable returns 503
- Inactive token with no recent trades may return stale or null price
- Malformed address format returns 400 validation error

## How this service works

## Output

Returns a JSON object containing the USD price of the specified token on the Monad network as sourced from DEX liquidity pools, along with optionally requested metrics such as 24hr volume, market capitalization, 24hr price change percentage, total reserve in USD, and FDV.
