## 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

```

Example prompt: Search Fiber AI for local marketing agencies in Austin, Texas and return their company details, key decision makers, and verified email and phone contacts — I want to reach out to them about a partnership.

## When to prefer this

Use this endpoint when you need to find and enrich local business contacts — including decision makers, emails, and phone numbers — for a specific geographic area or business type. Prefer this over person-search or LinkedIn-based endpoints when targeting local/SMB businesses rather than individuals with known LinkedIn profiles. Best for outbound sales prospecting, local lead generation, and building contact lists for local business outreach.

- Authentication failure returns 401 unauthorized
