## How to call it through Zero

```sh
zero fetch --capability pro-api-coingecko-com-076963f2
```

Example prompt: What's the current on-chain price of the token at contract address 0x008b2c67fe2e1a7a28105bd5e7d9760915907dbb on the Base network — and can you also include its 24-hour volume and price change?

## When to prefer this

Use this endpoint when you need the live on-chain price of a specific known token on the Coinbase Base network identified by its contract address, especially when you want DEX-sourced pricing rather than centralized exchange data. Prefer this over generic CoinGecko coin ID lookups when you have the contract address but not the CoinGecko coin slug.

## Known failure modes

- Invalid or unknown contract address returns empty or null price data
- Contract address not indexed by CoinGecko returns 404 or empty response
- Network identifier mismatch causes no data returned
- Rate limiting or missing API key returns 401/429 error
- Payment not processed returns 402 error

## How this service works

## Output

Returns a JSON object with the on-chain USD price for the specified Base network token contract, optionally including market cap, 24-hour trading volume, 24-hour price change percentage, and total reserve in USD as sourced from CoinGecko's on-chain DEX data.
