## How to call it through Zero

```sh
zero fetch --capability contactout-linkedin-profile-contact-lookup-3c665ab4
```

Example prompt: Can you find the email address and phone number for this LinkedIn profile: https://www.linkedin.com/in/johndoe — I need to reach out to them for a sales call.

## When to prefer this

Use this endpoint when you have a specific LinkedIn profile URL and need to find that person's email address or phone number for sales outreach, recruiting, or contact enrichment. Prefer this over the batch endpoint when looking up a single profile, and prefer it over the multi-field enrich endpoint when you already have the LinkedIn URL and don't need full work history or education data.

## Known failure modes
