The extraction type is the third segment of the provider slug you send to /v1/extract (e.g. the profile.info in apify/linkedin/profile.info). It specifies what data to extract.
Query-driven services (currently place.search on Google Maps) live on the POST /v1/search endpoint instead. The slug grammar is identical; only the endpoint and the type segment differ.

Platform coverage

Not every type is available on every platform, and coverage grows as new providers are added. Rather than baking a matrix here that drifts, query the live catalogue: 
curl https://api.socialrouter.io/v1/providers
Each provider entry advertises its supported_platforms, supported_types, and supported_search_types. The browsable list with copy-ready slugs is at socialrouter.io/providers.

​
Normalized response

Regardless of the provider, every extraction record includes at minimum: 
{
  "name": "string",
  "title": "string or null",
  "company": "string or null",
  "location": "string or null",
  "profile_url": "string",
  "source": "linkedin | instagram | x | reddit | facebook | tiktok | youtube | pinterest | bluesky | snapchat | googlemaps",
  "extracted_at": "ISO 8601 timestamp"
}
Some extraction types include additional fields (e.g., reaction_type for post.likes, experience and education arrays for profile.info).
