## 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-dex-trading-pairs-lookup-via-claw402-8e7eb38e
```

Example prompt: Show me the top 10 DEX trading pairs on the Ethereum network with at least $100,000 in 24-hour volume, sorted by volume descending — pull this from CoinMarketCap DEX data.

## When to prefer this

Use this endpoint when you need CoinMarketCap DEX pair data without registering for a CMC API key, and you can pay per-call in USDC via x402 protocol. Prefer it over direct CMC API access when operating in a wallet-native, keyless agent environment.

## Known failure modes

- Empty data array returned if no pairs match the filter criteria
- Payment not processed — 402 response if USDC wallet payment fails
- Invalid network_slug returns empty or error response
- Rate limiting or upstream CMC API errors return non-zero code
- Missing required query params may return empty or malformed response

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

Returns a JSON object with a status code and a data array containing DEX trading pair records, which may include pair names, contract addresses, liquidity figures, 24h volume, network info, and other auxiliary fields depending on query parameters.
