    Pass `tableId` to also persist matching results into an existing table. See [Contacts Tables](#tag/Contacts-Tables) or [Companies Tables](#tag/Companies-Tables).

      description: 'Find contacts similar to a set of seed contacts using AI-powered recommendations.


        Provide 5-100 seed contacts via LinkedIn URLs, emails, Lusha IDs, or name + company. The API returns contacts who share similar roles, seniority, and company profiles.


        **Pagination without duplicates:**

        On your first request, omit `dedupeSessionId` — the server generates one and returns it. Pass it on every subsequent request to get more results without repeating contacts already seen. Sessions are retained for 30 days.


        Use the `exclude` field to always filter out specific contacts (e.g. existing customers).


        Results are lightweight previews. Use Enrich Contacts with the returned `id` to get emails and phones.


        > **Billing:** Charged per result via the `lookalikeContact` action.


        > **Persisting to a table:** Pass `tableId` to also persist matching results into an existing table. See [Contacts Tables](#tag/Contacts-Tables).
