## 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 x402-token-price-history-b3bdbe26
```

Example prompt: What was Ethereum's price history over the last 30 days — give me the daily high, low, and overall change percentage?

## When to prefer this

Use this endpoint when you need historical USD price data for a crypto token identified by CoinGecko ID or on-chain address, especially when you want a time series with highs, lows, and percent change over a flexible window up to 365 days. Prefer this over raw blockchain data sources when you want clean, aggregated OHLC-style data without running your own indexer.

## Known failure modes

- Unknown CoinGecko ID returns 404 or empty result
- Invalid chain:address format causes a bad request error
- Date range outside 1–365 days may be rejected
- Token with no CoinGecko data (too new or delisted) returns no data
- Payment failure via x402 protocol blocks the request
