## 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 2s-io-crypto-coin-historical-market-chart-f794c0e4
```

Example prompt: Pull the historical price, market cap, and volume chart for bitcoin from CoinGecko over the last 90 days in USD so I can run a backtest.

## When to prefer this

Use this endpoint when you need historical cryptocurrency market data (price, market cap, volume) for backtesting, charting, or trend analysis over a flexible lookback window up to 1 year. Prefer it over real-time price endpoints when historical context or time-series analysis is the goal. Ideal when CoinGecko coin IDs are known and granularity auto-selection is acceptable.

## Known failure modes

- Invalid or unknown CoinGecko coin ID returns an error or empty result
- Days parameter out of range (below 1 or above 365) rejected by schema validation
- Unsupported vs-currency code returns an error
- Rate limiting or payment failure (x402) prevents data retrieval
- CoinGecko upstream outage causes degraded or missing data

## How this service works

Historical market chart for a coin by CoinGecko id: time-series of price, market cap, and volume over the last N days (1-365) in USD or another vs-currency. Granularity is auto-selected by range (hourly for short windows, daily for long). For backtests, charts, and trend analysis.

## Output

A time-series dataset containing price, market cap, and total volume data points for the requested cryptocurrency over the specified lookback window, denominated in the chosen vs-currency. Granularity is automatically set to hourly for short windows and daily for longer ones.
