Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Look up the contact details — emails and phone numbers — for these 5 LinkedIn profiles: linkedin.com/in/johndoe, linkedin.com/in/janedoe, linkedin.com/in/bobsmith, linkedin.com/in/alicejones, linkedin.com/in/carlwhite.

## When to prefer this

Use this endpoint when you need to enrich multiple LinkedIn profiles with contact details in a single API call (up to 30 at a time), making it efficient for batch sales prospecting, recruiting, or outreach workflows where individual lookups would be too slow or costly.
