## 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 coingecko-historical-chart-data-137050ca -d '<json body>'
```

Example prompt: Show me the daily price and market cap history for Ethereum in USD over the last 90 days.

## When to prefer this

Use this endpoint when you need historical price, volume, or market cap time-series data for a specific cryptocurrency. Prefer this over live price endpoints when you need trend analysis, charting, or backtesting. Choose it over broader market endpoints when you have a specific coin and time range in mind.

## Known failure modes

- Invalid coin ID returns an error — use CoinGecko slug format (e.g. 'bitcoin', not 'BTC')
- Unsupported days value causes rejection — must be 1, 7, 14, 30, 90, 180, 365, or 'max'
- Unsupported vs_currency value results in error
- Payment failure if USDC balance is insufficient for the $0.01 per-call fee
- Rate limiting or upstream CoinGecko API unavailability may return 503
