## 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 pro-api-coingecko-com-df8dbec7
```

Example prompt: What's the current onchain price and 24-hour volume for the token at contract address 0x0004a2c7a40d97add19a428dae3fab4654c0c4a8 on the Base network? Include market cap and price change too.

## When to prefer this

Use this endpoint when you specifically need onchain DEX-sourced price data for this exact token contract on the Base network, rather than CEX prices. Ideal for DeFi applications, portfolio trackers, or agents monitoring Base-native tokens that may not be listed on centralized exchanges. Prefer this over the generic simple/price endpoint when you need DEX liquidity-based pricing or reserve data.

## Known failure modes

- Token contract address not found on Base network — returns empty data or 404
- Invalid or inactive token contract returns no price data
- Network identifier mismatch causes no results
- Rate limit or authentication failure returns 401/429
- Token has insufficient liquidity on DEX — price may be stale or unavailable

## 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 the token's current USD price sourced from onchain DEX liquidity pools on Base, along with optional fields: 24hr trading volume, market cap, 24hr price change percentage, and total reserve in USD — all indexed by the contract address.
