## 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-linkedin-post-comments-fetcher-9701d07b -d '<json body>'
```

Example prompt: Can you pull the comments from this LinkedIn post — https://www.linkedin.com/posts/example-post-id — and give me the first page of up to 10 comments so I can see who's engaging with it?

## When to prefer this

Use this endpoint when you need to extract and analyze public comments on a specific LinkedIn post, such as for lead generation, sentiment analysis, audience research, or competitive intelligence. Prefer this over manual scraping when you need structured, paginated comment data with commenter profile details attached.

## Known failure modes

- Invalid or inaccessible LinkedIn post URL/ID returns an error
- Post has no comments returns empty results
- Invalid pagination cursor returns an error or unexpected page
- Rate limiting or quota exceeded returns a 429 or quota error
- Private or restricted post returns an authorization error

## How this service works

Fetches paginated comments for a LinkedIn post. Each page contains up to 10 comments. Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

## Output

Returns a paginated list of up to 10 comments per page for the specified LinkedIn post, including commenter profile details, comment text, timestamps, and a cursor for fetching the next page of comments.
