  - name: Invitation
    description: Invitation endpoint. Exists to invite users to an organization.
  - name: Auth
    description: Authentication endpoint. Serves to register and authenticate users.
  - name: User
    description: User endpoint. Enables you to modify user roles and information.

    description: >-
      Organization endpoint. Enables you to modify organization roles and
      information.
  - name: Dataset
    description: >-
      Dataset endpoint. Datasets belong to organizations and hold configuration
      information for both client and server. Datasets contain chunks and chunk
      groups.
  - name: Chunk
    description: >-
      Chunk endpoint. Think of chunks as individual searchable units of
      information. The majority of your integration will likely be with the
      Chunk endpoint.
  - name: Chunk Group
    description: >-
      Chunk groups endpoint. Think of a chunk_group as a bookmark folder within
      the dataset.
  - name: Crawl
    description: Crawl endpoint. Used to create and manage crawls for datasets.
  - name: File
    description: >-
      File endpoint. When files are uploaded, they are stored in S3 and broken
      up into chunks with text extraction from Apache Tika. You can upload files
      of pretty much any type up to 1GB in size. See chunking algorithm details
      at `docs.trieve.ai` for more information on how chunking works. Improved
      default chunking is on our roadmap.
  - name: Events
    description: >-
      Notifications endpoint. Files are uploaded asynchronously and events are
      sent to the user when the upload is complete.
  - name: Topic
    description: >-
      Topic chat endpoint. Think of topics as the storage system for gen-ai chat
      memory. Gen AI messages belong to topics.
  - name: Message
    description: >-
      Message chat endpoint. Messages are units belonging to a topic in the
      context of a chat with a LLM. There are system, user, and assistant
      messages.
  - name: Stripe
    description: >-
      Stripe endpoint. Used for the managed SaaS version of this app. Eventually
      this will become a micro-service. Reach out to the team using contact info
      found at `docs.trieve.ai` for more information.
  - name: Health
    description: Health check endpoint. Used to check if the server is up and running.
  - name: Metrics
    description: Metrics endpoint. Used to get information for monitoring
  - name: Analytics
    description: Analytics endpoint. Used to get information for search and RAG analytics
  - name: Experiment
    description: Experiment endpoint. Used to create and manage experiments
