## 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-coin-data-6116e09f -d '<json body>'
```

Example prompt: What did Bitcoin look like on 01-01-2021? Can you pull the historical snapshot from CoinGecko — price, market cap, volume, all of it — for that exact date?

## When to prefer this

Use this endpoint when you need point-in-time historical cryptocurrency data for a specific past date — such as auditing portfolio performance on a past date, backtesting trading strategies, or researching market conditions on a historical event date. Prefer this over live price endpoints when the date of interest is in the past and you need full snapshot data including community and developer metrics.

## Known failure modes

- Invalid coin ID returns an error or empty response
- Date in wrong format (not dd-mm-yyyy) causes a validation error
- Date in the future or before coin listing returns no data
- Network timeout or upstream CoinGecko API unavailability returns a 5xx error
- Payment not fulfilled results in 402 Payment Required response
