APIMart is for developers and teams that want to build AI features without managing separate accounts and integrations for each model provider. It provides a single gateway to text and chat, image, video, and audio models, so teams can use different models for tasks such as adding an AI assistant, generating images, or creating video in an application. For supported chat models, APIMart uses an OpenAI-compatible API, allowing developers to connect with familiar SDKs by changing the API endpoint and key. A dashboard brings together API keys, model access, usage monitoring, and billing. Developers can also test models in a playground and use APIMart’s agent tools to help AI coding agents discover models and work with image and video tasks. Image and video APIs may use their own request formats, so check the documentation for the model you plan to use.
