## 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-6097a507
```

Example prompt: Can you pull the current onchain DEX prices, 24-hour volume, and market caps for these Base network tokens — 0x4200000000000000000000000000000000000006 and 0xacfe6019ed1a7dc6f7b508c02d1b04ec88cc21bf — from CoinGecko?

## When to prefer this

Use this endpoint when you need onchain DEX-sourced prices for multiple token contract addresses simultaneously on the Base network, especially when you want granular market data (volume, market cap, reserves, price change) from decentralized exchange liquidity pools rather than centralized exchange data. Prefer this over single-token endpoints when batching multiple Base token lookups in one call to minimize cost and latency.

## Known failure modes

- Invalid or unrecognized contract address returns empty or null price data for that token
- Network not supported returns 404 or error response
- Too many contract addresses in a single request may return partial results or rate limit error
- Inactive token with no recent DEX trades may return null if include_inactive_source is false
- API key invalid or missing returns 401 Unauthorized
- Rate limit exceeded returns 429 Too Many Requests

## How this service works

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

## Output

A JSON object mapping each requested contract address to its current onchain DEX price (in USD or supported currency), and optionally 24hr trading volume, market cap, 24hr price change percentage, and total reserve in USD — all sourced from DEX liquidity pools on the Base network.
