What it is

Use calfkit-sdk to create custom AI agents for your business as event-driven microservices.

Real use case example

"A founder wants to automate email notifications when a new order is placed on their e-commerce site. They use calfkit-sdk to build an AI agent that listens for new order events, triggers an email notification via Stripe, and updates the customer's status in their CRM. This automation saves them 2 hours of manual work each week."
