## 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-onchain-dex-token-price-arbitrum-network-4fc17b5b
```

Example prompt: Can you look up the current onchain DEX price and 24-hour trading volume for the Arbitrum token at contract address 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1, including market cap and price change?

## When to prefer this

Use this endpoint when you need real-time onchain DEX pricing for tokens on the Arbitrum network specifically, especially for newer or smaller tokens not yet listed on centralized exchanges. It is ideal when you need DEX-derived prices (not CEX prices), liquidity/reserve data, or market data sourced directly from onchain pool activity. Prefer this over generic CoinGecko coin endpoints when you have a contract address rather than a coin ID, or when the token may only exist onchain.

## Known failure modes

- Token contract address not found on Arbitrum — returns empty or null price data
- Invalid contract address format — returns 400 bad request
- Token exists but has no active DEX liquidity — price may be unavailable
- Rate limit exceeded on pro API tier — returns 429 too many requests
- Network-specific data unavailable due to node issues — returns 503
- Inactive token with no recent trading — may return stale or missing data

## How this service works

Query onchain DEX token price & market data based on the provided token contract addresses on a network.

## Output

Returns a JSON object containing onchain DEX market data for the specified token contract on Arbitrum, including the current USD price derived from DEX pool data, and optionally 24-hour trading volume, market capitalization, 24-hour price change percentage, and total reserve in USD across liquidity pools.
