Run the same filters as POST /leads/advanced_search and get back a synchronous preview: the total estimated profile count plus the first 25 matching leads. Use it to validate filters and size an audience before kicking off the real search.

​
Overview

Compared to POST /leads/advanced_search, the preview:
  • Does not create a Search record.
  • Does not call your webhook.
  • Does not consume credits.
  • Does not require webhook_url.
The body accepts the exact same filter parameters as the regular advanced search — see Search leads by filters for the full reference. webhook_url, name, limit, streaming, scale, and custom are accepted but ignored: the response always contains up to 25 leads.

​
Requirements

  • A valid integration must be connected on the authenticated user.
  • At least one filter or keyword must be provided.

​
Rate Limits

  • 1 request per second per user.

​
