## 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 vextorium-token-price-history-3bb839d8 -d '<json body>'
```

Example prompt: Can you pull the daily price history for ETH over the last 90 days and tell me the annualized volatility, maximum drawdown, and total price change?

## When to prefer this

Choose this endpoint when you need a full daily price time series plus risk metrics (volatility, drawdown) for any major crypto token or long-tail DeFi token addressable by chain:contract. It is particularly useful when you want DefiLlama-aggregated data rather than a single exchange feed, and when you need computed statistics (annualized volatility, max drawdown) pre-calculated alongside raw prices — saving you from computing these yourself.

## Known failure modes

- Unknown or misspelled token symbol returns null or empty series
- Invalid chain:contract format results in an error or empty response
- Requesting more than 365 days or fewer than 2 days may return an error or default to 30 days
- Token not tracked by DefiLlama returns no data
- Network or payment failure returns a non-200 status

## How this service works

Daily price series of a token for up to 365 days with change, high, low, maximum drawdown and annualized volatility. Accepts symbols (BTC, ETH, SOL...) or chain:contract ids. Aggregated by DefiLlama.

## Output

A JSON object containing the token symbol, data source (DefiLlama), the number of days requested, an array of daily {date, price} entries, the initial and final prices, percentage change over the period, maximum and minimum prices, maximum drawdown percentage, and annualized volatility percentage.
