## How to call it through Zero

```sh
zero fetch --capability pro-api-coingecko-com-fe89563a
```

Example prompt: What's the current onchain price and 24-hour price change for the token at contract address 0x00393c0b6e606ed053ee0abb5df2199f450685f1 on the Base network, including its market cap and trading volume?

## When to prefer this

Use this endpoint when you need real-time onchain DEX price data specifically for the token at contract 0x00393c0b on the Base network via CoinGecko Pro. Prefer this over general CoinGecko coin price endpoints when you need DEX-sourced onchain pricing rather than aggregated CEX/CoinGecko index prices, and when the token may not have a CoinGecko coin ID but does have a Base contract address.

## Known failure modes

- Token contract address not found on Base network — returns empty or null data
- Token is inactive and include_inactive_source is false — returns no data
- Network congestion or CoinGecko Pro API downtime — returns 5xx error
- Invalid or malformed contract address — returns 400 or empty response
- Payment not processed or x402 auth failure — returns 402 Payment Required
