## 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 edges-linkedin-profile-comment-activity-extractor-1a09a919 -d '<json body>'
```

Example prompt: Can you pull the comment activity history for this LinkedIn profile — https://www.linkedin.com/in/janedoe — and show me all the posts they've recently commented on?

## When to prefer this

Use this endpoint when you need to audit or analyze what posts a specific LinkedIn user has been commenting on, understand their engagement patterns, or research their professional interests and interactions. Prefer this over general profile extraction when comment-level activity (not just profile metadata) is the target.

## Known failure modes

- LinkedIn profile not found or URL invalid — returns error with no data
- Profile is private or has restricted activity visibility — returns empty or partial results
- LinkedIn rate limiting or anti-scraping block — returns failure or timeout
- Malformed profile URL input — returns validation error
- Profile has no public comment activity — returns empty list
