## 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-by-contract-address-af11609c
```

Example prompt: What's the current on-chain DEX price for the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on the Ethereum network — and can you also pull the 24-hour volume and price change?

## When to prefer this

Prefer this endpoint when you need on-chain DEX-sourced price data for a specific token contract address rather than CoinGecko's centralized exchange aggregated prices. Ideal for DeFi applications, smart contract token price checks, or when you have a contract address but no CoinGecko coin ID. Best for Ethereum, Base, Solana, and other supported EVM/non-EVM networks where DEX liquidity is the primary price source.

## Known failure modes

- Invalid or unsupported network name returns an error or empty data
- Unknown or untraded contract address returns no price data
- Malformed contract address format causes a 400 or empty response
- Token with no recent DEX activity may return stale or null timestamps
- Rate limiting or payment failure returns a 402 or 429 error
- Requesting too many addresses at once may result in partial or truncated results

## How this service works

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

## Output

Returns a structured data object keyed by token contract address containing: current USD token price, optional 24-hour trading volume, optional market cap, optional 24-hour price change percentage, optional total reserve in USD, and optional last trade timestamp — all sourced from on-chain DEX activity.
