## 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

Example prompt: Can you pull the trading volume history for Binance (exchange ID: binance) over the last 30 days so I can see how volume has trended?

## When to prefer this

Use this endpoint when you need historical trading volume data for a specific centralized or decentralized exchange over a configurable time window. Prefer this over general price endpoints when the user's question is specifically about exchange-level volume trends rather than coin prices or market cap.

## Known failure modes

- Invalid exchange ID returns an error or empty result
- Unsupported or out-of-range 'days' value may return an error
- Exchange not tracked by CoinGecko returns a not-found error
- Network or upstream CoinGecko API downtime causes failure
- Malformed request body missing required fields returns validation error
