## How to call it through Zero

```sh
zero fetch --capability coinmarketcap-d5ecb71e
```

Example prompt: What's the latest price and market data for the DEX pair at contract address 0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640 on Ethereum (network ID 1), quoted in USD?

## When to prefer this

Use this endpoint when you need real-time quote data for a specific DEX trading pair and you already have the contract address. Ideal for DeFi applications, trading bots, portfolio trackers, or price alert systems that need precise on-chain pair pricing. Prefer this over general crypto quote endpoints when the asset is a DEX-listed token pair rather than a top-level CMC-listed coin.

## Known failure modes

- Invalid or non-existent pair_address returns an error or empty result
- Unsupported network_id may return no data
- Malformed comma-separated pair_address list causes validation error
- Requesting a pair on a network where CoinMarketCap has no data returns empty
- Payment failure via x402 protocol blocks the request
- Rate limiting if too many requests are made in quick succession
