## 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 socialfetch-linkedin-posts-search-1eb30eb6
```

Example prompt: Search LinkedIn for public posts mentioning 'generative AI in healthcare' from the last week and show me what people are saying.

## When to prefer this

Use this endpoint when you need to search and retrieve public LinkedIn posts by keyword or topic, especially with recency filters (last hour, day, week, month, or year). Prefer this over general web search when you specifically want LinkedIn professional content and post-level data with pagination support.

## Known failure modes

- Empty results if no public LinkedIn posts match the keyword
- Invalid or expired pagination cursor returns an error
- Query exceeding 512 characters is rejected
- Unsupported datePosted enum value causes a validation error
- Rate limiting or payment failure results in 402 response
- LinkedIn access restrictions may reduce result availability

## How this service works

Search public LinkedIn posts site-wide by keyword (not scoped to one profile or company — use linkedin.profiles.posts.list or linkedin.company.posts.list for that).

## Output

A list of public LinkedIn posts matching the search query, including post content and metadata, with an opaque cursor for fetching the next page of results.
