## Playbook

# Firmable

Use Firmable only after the workspace connects its own Firmable API key.

* Use `firmable_company_lookup` when you have a company identifier, domain, website, or LinkedIn profile.
* Use `firmable_person_lookup` when you have a Firmable person ID, LinkedIn profile, or email address.
* Use `firmable_people_search` to find people at a known Firmable company ID, then narrow by country, position, seniority, or department.
* Firmable usage may count against the connected account plan or quota even though Deepline does not charge for these BYOK calls.
