## 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`):

```

Example prompt: Search the Purch shop for wireless noise-cancelling headphones under $150, and I prefer well-reviewed brands with good battery life.
