Example prompt: Can you pull the latest startup platform posts for Notion from PredictLeads — I want to see their Product Hunt launches and Hacker News activity to gauge their recent growth signals?

## When to prefer this

Use this endpoint when you need to discover startup platform activity (Product Hunt launches, Hacker News posts) for companies as growth or sales signals. Prefer this over the News Events endpoint when you specifically want platform-native posts from startup communities rather than broader press coverage or news articles.

## Known failure modes

- No posts found for the specified company or filter — returns empty results
- Invalid or unrecognized query parameters — returns 400 error
- Authentication failure — returns 401 unauthorized
- Rate limit exceeded — returns 429 too many requests
- Platform temporarily unavailable — returns 503 error

## How this service works

Discover posts from startup platforms (Product Hunt, Hacker News, etc.) 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 list of posts from startup platforms (such as Product Hunt and Hacker News) associated with companies, including post metadata such as platform name, post title, date, and engagement signals that indicate company activity and launch momentum.
