## 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 x402node-token-price-chart-series-7b1a17ca
```

Example prompt: Can you pull the hourly USD price series for the USDC token on Ethereum (contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) over the last 7 days so I can chart its trend and volatility?

## When to prefer this

Use this endpoint when you need a historical or recent price time series for a specific token — especially for charting, trend analysis, or volatility computation — and you can identify the token by chain + contract address or CoinGecko ID. Prefer over single-price endpoints when you need multiple data points over time rather than just a spot price.

## Known failure modes

- Invalid or unrecognized contract address returns an error
- Unsupported chain identifier returns an error
- Unknown CoinGecko ID returns not found
- Interval or window parameter out of supported range returns a validation error
- Payment not fulfilled results in 402 Payment Required response
