## 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 crypto-price-history-0196e346
```

Example prompt: Can you pull up the daily price history for Ethereum over the last 90 days, including the high, low, and percentage change each day?

## When to prefer this

Use this endpoint when you need historical daily OHLC-style (open/high/low/close) price data for any cryptocurrency — especially for cost basis calculations, backtesting, charting, or answering 'what was X worth on Y date' questions. It accepts flexible token identifiers (symbol, CoinGecko id, or chain:address), making it more versatile than endpoints requiring a specific format. Prefer this over real-time price endpoints when the user's question is about the past rather than the present.

## Known failure modes

- Unknown token symbol or CoinGecko id returns a 404 or empty result
- Days parameter outside the 2-365 range returns a validation error
- Invalid date format for 'on' parameter (not YYYY-MM-DD) returns a parse error
- Token contract address with unsupported chain prefix returns an error
- Very recently listed tokens may have incomplete historical data
- Rate limiting or upstream CoinGecko outage may cause 5xx errors

## How this service works

Daily USD price history of any token (symbol, CoinGecko id or chain:address) for up to 365 days with high, low and % change, or its exact price on a past date. Use for charts, backtests, cost basis or 'what was ETH worth on...' questions.

## Output

Returns an array of daily price records for the requested token, each containing the date, USD price, daily high, daily low, and percentage change. For a single-date query using the 'on' parameter, returns the exact USD price on that date. Data is sourced from CoinGecko and covers up to 365 days of history.
