## 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 questflow-21c5f0c3 -d '<json body>'
```

Example prompt: What's the current price, market cap, and 24-hour trading volume for Ethereum, and which exchanges have the highest liquidity for it right now?

## When to prefer this

Use this endpoint when you need comprehensive, aggregated cryptocurrency market data — prices, volumes, market caps — across a wide range of assets and exchanges. Prefer this over exchange-specific APIs when breadth of coverage matters. Best for informational queries rather than trade execution.

## Known failure modes

- Unknown or very new token not yet indexed by CoinGecko returns empty or error response
- Ambiguous ticker symbol (e.g. multiple tokens with same symbol) may return incorrect asset
- Rate limits or payment failure result in 402 or 429 error
- Exchange-specific data unavailable for low-liquidity pairs
