 Integuru is built by Integuru.ai. Besides our work on the agent, we take custom requests for new integrations or additional features for existing supported platforms. We also offer hosting and authentication services. If you have requests or want to work with us, reach out at [email protected].
 
 We open-source unofficial APIs that we've built already. You can find them [here](https://github.com/Integuru-AI/APIs-by-Integuru).
