## 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-contact-reveal-single-linkedin-to-email-phone-c4eb5145 -d '<json body>'
```

Example prompt: Can you get me the email address and phone number for this person on LinkedIn — https://www.linkedin.com/in/johndoe — I want to reach out to them directly?

## When to prefer this

Use this endpoint when you have a specific person's LinkedIn profile URL and need their verified email or phone number for outreach. Prefer this over batch endpoints for single lookups, and over reverse email lookup when the LinkedIn URL is the known identifier. Best for sales prospecting, recruiting, and CRM enrichment workflows where LinkedIn is the primary identifier.

## Known failure modes

- Person has no available contact data in Fiber's database — returns empty contacts
- Rate limiting or authentication failure — returns 401/429 error
- Malformed LinkedIn URL — returns validation error
- Profile is private or otherwise unavailable — no data returned
