Tool use turns an LLM into an 'agent that takes action'. When the bot hears 'find apartments in Kadıköy', it doesn't just generate text — it calls the search_listings tool, pulls real DB results, formats them for the user. LeadsUp ships 12+ default tools; custom HTTP tool lets you bind your own APIs.
Example
When bot hears 'I want to pay a deposit', it calls create_payment_link, generates a Stripe link and shares via WhatsApp.
