## 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 contactout-batch-linkedin-profile-enrichment-edd350bf -d '<json body>'
```

Example prompt: I have a list of 25 LinkedIn profile URLs for candidates I'm sourcing — can you pull their email addresses and phone numbers all at once using ContactOut's batch lookup?

## When to prefer this

Use this endpoint when you need to enrich multiple LinkedIn profiles (2–30) simultaneously rather than making individual API calls per profile. Ideal for bulk recruiting sourcing, sales prospecting, or CRM enrichment workflows where you have a list of LinkedIn URLs and need email/phone data efficiently in a single request.

## Known failure modes

- Batch size exceeds 30 profiles — request rejected
- Invalid or malformed LinkedIn profile URLs — partial or empty results for those entries
- LinkedIn profiles are private or data unavailable — null/empty fields for those contacts
- Authentication failure — 401 unauthorized if API token is missing or invalid
- Rate limit exceeded — 429 too many requests
- Profile not found in ContactOut database — no contact data returned for that entry
