# Lookalikes

**Lookalike APIs:** Use AI-powered recommendations to discover contacts and companies similar to your best existing customers. The Contact Lookalikes and Company Lookalikes endpoints return paginated results you can pipe directly into Enrich for full data.


## Contact Lookalikes

 - [POST /v3/contacts/lookalike](https://docs.lusha.com/apis/openapi/lookalikes/getcontactlookalikes.md): 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.
