## 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 coinmarketcap-d0f05b6e
```

Example prompt: Search CoinMarketCap's DEX data for the token 'PEPE' — I want to find its contract address and which decentralized exchanges list it.

## When to prefer this

Use this endpoint when you need to search for a specific token across decentralized exchanges by name, symbol, or contract address, especially when you want CoinMarketCap's authoritative DEX coverage. Prefer over spot price endpoints when you need to discover or verify a token's DEX presence rather than fetch a known quote.

## Known failure modes

- No results found for unrecognized or very new tokens
- Missing required 'q' query parameter returns validation error
- Rate limiting or payment failure for x402 micropayment
- Token exists on CEX but not indexed in DEX data
