## 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-ceb0596a
```

Example prompt: What's the current onchain price on Arbitrum for the token at contract address 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8, and can you also include the 24-hour price change and market cap?

## When to prefer this

Choose this endpoint when you need real-time, DEX-sourced token prices specifically on the Arbitrum network using a contract address. It is ideal for DeFi agents, portfolio trackers, and trading bots that need onchain price discovery rather than centralized exchange prices. Prefer this over generic CoinGecko coin ID-based endpoints when you have a contract address and need Arbitrum-specific onchain data including liquidity metrics.

## Known failure modes

- Invalid or unrecognized contract address returns empty or error response
- Token not listed on any Arbitrum DEX returns no price data
- Malformed address path parameter causes 400 Bad Request
- Payment not processed (x402) results in 402 Payment Required
- Rate limiting or quota exceeded returns 429 Too Many Requests
- Network outage or CoinGecko downtime returns 5xx error

## How this service works
