How this service works
Search for professional network posts using filters like author profile URL or keywords. Pass filters in the request body (not a post URL). Returns an array of numeric post IDs (e.g., ["7431869637207928834", ...]). Use these IDs with the 'Employee Posts Collect' endpoint to get full post content.
Output
An array of numeric Coresignal post IDs matching the specified filters, which can then be used to retrieve full post details from a subsequent enrichment endpoint.
Example use cases
Example prompt
“Can you find recent professional network posts from the author at linkedin.com/in/johndoe that mention 'artificial intelligence' using Coresignal's post filter search?”
Technical details
Endpoint
POSThttps://mpp.orthogonal.com/coresignal/v2/employee_post/search/filter?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search and filter professional network posts by author profile URL or keywords, specifically within Coresignal's 3B+ record database. Prefer this over general web scraping when you need structured, regularly updated post data tied to known employee profiles. Use it as a first step to retrieve post IDs before enriching with full post details.
