## 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 crypto-market-chart-price-market-cap-volume-fe9a9f91 -d '<json body>'
```

Example prompt: Can you pull the historical price, market cap, and volume data for Ethereum over the last 90 days in USD so I can chart the trend?

## When to prefer this

Choose this endpoint when you need continuous time-series data (price, market cap, and volume aligned by timestamp) over a multi-day window, especially for charting, trend analysis, volume studies, or backtesting. Prefer this over OHLC candles when you need finer granularity or market-cap data alongside price. Use the sibling OHLC endpoint instead if you specifically need open/high/low/close candles for candlestick charts.

## Known failure modes

- Invalid coin id or ticker returns an error or empty dataset
- Days value outside 1–365 range is rejected
- Unsupported vsCurrency may return an error
- Rate limiting or payment failure returns a 402 or 429 status
- Coin with low liquidity may have sparse or missing volume data points

## How this service works

Historical crypto price, market cap and volume time series. Given a coin id or ticker and a window of days (1-365) returns aligned price, market-cap and total-volume points with ISO timestamps — finer-grained than OHLC candles. For charting, market-cap trend analysis, volume studies, backtesting and portfolio agents.

## Output

Returns aligned time-series arrays of price (in the specified vs-currency), market cap, and total volume, each paired with ISO timestamps. Granularity is auto-selected by CoinGecko based on the requested day range (e.g., hourly for short windows, daily for longer ones).
