## 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-f25f073c
```

Example prompt: Can you pull the current on-chain DEX prices and 24-hour price changes for WETH (0x4200000000000000000000000000000000000006), Aerodrome (0x940181a94a35a4569e4529a3cdfb74e38fd98631), and 0x9b5e262cf9bb04869ab40b19af91d2dc85761722 on the Base network using CoinGecko?

## When to prefer this

Use this endpoint when you need real-time on-chain DEX price data for specific token contract addresses on the Base network, especially when you want to query multiple tokens in a single call. Prefer this over CoinGecko's off-chain coin price endpoint when you need DEX-sourced pricing or when you have contract addresses rather than CoinGecko coin IDs.

## Known failure modes

- Invalid or unsupported contract address returns empty or missing data for that token
- Network not supported returns 404 or empty response
- Exceeds rate limit or payment not processed returns 402 or 429
- Malformed contract address format causes 400 bad request
- Token has no on-chain liquidity data returns null price fields

## 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 keyed by token contract address, each containing the current USD price sourced from on-chain DEX data, and optionally 24hr volume, market cap, 24hr price change, and total reserve in USD depending on query flags.
