# Get started with REST API

JTheta.ai offers a powerful REST API for programmatic access to all platform functionalities. While the web platform provides an intuitive interface to create projects, upload images, assign annotation tasks, and export labeled datasets, the REST API enables developers and data teams to automate these operations at scale.

With the API, you can create and manage projects, upload large batches of images, trigger AI-assisted annotation, assign annotators and reviewers, and download completed labels — all through secure, authenticated endpoints. This is especially useful when working with high-volume datasets or integrating JTheta.ai into your custom MLOps workflows.

Whether you prefer the convenience of the web UI or the flexibility of the REST API, JTheta.ai supports a seamless and scalable annotation experience to match your needs.

You need a API key to use REST API.Refer to the following documentation on how to create API key:
