Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh

Example prompt: Can you pull the historical price chart for bitcoin over the last 7 days — I want to see the price points and what percentage it's changed?

## When to prefer this

Choose this endpoint when you need time-series historical price data for a specific cryptocurrency token, especially when you want both raw price arrays and a summary (current price + change percentage) in a single call. Ideal for charting, trend analysis, or DeFi research use cases within an AI agent pipeline that supports x402 micropayments.

## Known failure modes

- Unknown token_id returns an error or empty dataset
- Invalid or out-of-range 'days' value may cause a bad request response
- Network/service downtime on Hugging Face Spaces hosting
- Payment failure via x402 micropayment ($0.005 USDC) blocks the request
- Rate limiting if too many calls are made in quick succession
