## 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-reactions-fetcher-f76ecc21 -d '<json body>'
```

Example prompt: Can you fetch the first page of 'like' reactions on this LinkedIn post — https://www.linkedin.com/posts/somecompany_activity-12345 — and show me who reacted?

## When to prefer this

Use this endpoint when you need to enumerate and analyze who has reacted to a specific LinkedIn post, broken down by reaction type. Ideal for lead generation, engagement tracking, or identifying warm prospects who have shown interest in a post. Prefer this over profile-based endpoints when your starting point is a LinkedIn post rather than a person or company.

## Known failure modes

- Invalid or inaccessible LinkedIn post URL returns an error
- Unsupported reaction type enum value causes a validation error
- Expired or invalid pagination cursor results in an error
- Post has no reactions of the requested type, returning an empty list
- Rate limit exceeded returns a 429 error
- Network timeout for posts with very large reaction counts

## How this service works

Fetches paginated reactions of a specific type for a LinkedIn post. Each page contains up to 10 reactions. 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 reactions for the specified LinkedIn post and reaction type, including details about each person who reacted (profile info, reaction type), and a cursor for fetching the next page.
