## 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 agent402-coin-market-chart-range-3a85abf5
```

Example prompt: Can you pull the historical price and volume data for ethereum in USD from August 1st to August 22nd 2026, including the high, low, and percent change summary?

## When to prefer this

Choose this endpoint when you need time-series cryptocurrency price, volume, and market cap data over a specific historical range with summary statistics (high, low, change%) included. It is ideal for backtesting, charting, portfolio reviews, or any workflow requiring structured OHLCV-style data for a named coin without managing CoinGecko API keys directly. Prefer it over general crypto tickers when you need range data rather than a single current price.

## Known failure modes

- Unknown coin id returns an error or empty result — use CoinGecko slug format (e.g. 'bitcoin', not 'BTC')
- Invalid or unparseable date formats in from/to fields may cause a 400-level error
- Requesting very long historical windows may result in coarser granularity or truncated data
- If the requested window exceeds available data history, the response may be partial
- Network or upstream CoinGecko unavailability may result in a 5xx or timeout response

## How this service works

Price, market cap and volume series for a coin over an ARBITRARY time window: `from`/`to` as unix seconds or ISO dates, or `lookback` ("6h", "3d", "2w") ending now. Granularity is automatic upstream: 5-minute points for a window of 1 day or less, hourly up to 90 days, daily beyond. The windowed sibling of crypto-history (which counts days back from now): use it to align with a specific event, a filing date or another series.

## Output

Returns a JSON object with the queried coin id, from/to timestamps, number of data points, granularity (e.g. 1h), an array of time-series points each containing time, price, volume, and market cap, a summary object with low/high/first/last/changePct values, the currency, data source (CoinGecko), fetchedAt timestamp, and a cached flag.
