## 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 fiber-ai-api-fiber-ai-person-search-2f0ea603 -d '<json body>'
```

Example prompt: Can you look up the contact details for the person with LinkedIn slug 'john-doe-123' at Acme Corp — I need their verified email and phone number?

## When to prefer this

Use this endpoint when you have a LinkedIn identifier (slug or URL) or a person's current company and need to retrieve verified contact details including email and phone. Prefer this over generic search endpoints when you already know who you're looking for and want the most accurate enrichment data available. Ideal for sales prospecting, lead enrichment, and outreach workflows.

## Known failure modes

## How this service works

## Output

An enriched person record including verified email address, phone number, LinkedIn profile details, and other personal contact data associated with the matched individual
