How to choose AI API marketplaces

Your choice depends on what you want to create and how you prefer to manage model access. Start with your main job, then check model connections, support, and billing needs.

    Bring several models together

    For AI API aggregation, focus on the models and services already in your workflow. A shared setup can also make multi-model AI generation easier to manage.

    Creative work may start with AI image generation and later expand into image-to-video or full video creation. Pick around the media jobs you expect to run most often.

    • MaxAPI suits workflows that generate or edit images, turn images into video, and route work between models.
    • Legnext focuses on image and video generation, including batch art creation and access to Midjourney through an API.
    • Atlas Cloud combines image and video generation with model hosting and image-to-video work.

    Manage chat models and usage

    Chat products often need an LLM API for chat, model routing, and a clear view of usage. One billing layer can also reduce the work of handling separate providers.

    • CometAPI helps you compare and route models while tracking usage across a shared setup.
    • RouterBase brings chat model switching, routing, usage tracking, and shared billing into one service.
    • BeatAPI gives chat, image, and video projects one place for model access and billing.
