## 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-lookup-base-network-multi-token-d53c3c85
```

Example prompt: Can you pull the current onchain DEX prices and 24-hour price changes for these four Base network token contracts — 0x0b3e328455c4059eeb9e3f84b5543f74e24e7e1b, 0x22af33fe49fd1fa80c7149773dde5890d3c76f3b, 0xacfe6019ed1a7dc6f7b508c02d1b04ec88cc21bf, and 0xc0634090f2fe6c6d75e61be2b949464abb498973 — including their market caps and 24-hour trading volumes?

## When to prefer this

Use this endpoint when you need real-time onchain DEX price data for one or more specific token contract addresses on the Base network, especially when you want optional enrichment like market cap, 24hr volume, or price change. Prefer this over CoinGecko's standard simple/price endpoint when dealing with newer or less-liquid tokens that are primarily traded on DEXes and may not have a CoinGecko coin ID.

## Known failure modes

- Invalid or malformed contract address returns empty or error response
- Unsupported network identifier returns 404 or error
- Token not indexed by CoinGecko onchain data returns null values
- Rate limiting or authentication failure returns 401/429
- Inactive token with no recent DEX trades may return stale or missing price 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 real-time onchain price data for each queried token contract address on the Base network, including USD price, and optionally 24hr volume, market cap, 24hr price change, total reserve in USD, and inactive source data depending on query parameters.
