  title: NPC Builder - API
  description: >
    This is the latest NPC Builder API specification that defines a
    comprehensive, production-ready API for NPC Builder. The API is divided into
    three primary services:


    **Interactions Service**  
      - **Purpose:** Enables dynamic, context-aware conversations between players and NPC characters.


    **Context Service**  
      - **Purpose:** Manages in-game entities to build and maintain immersive game environments.
      - **Includes:**  
        - **Worlds:** Create, update, and delete game worlds.
        - **Regions:** Define and manage distinct regions within a world.
        - **Locations:** Handle specific locations within regions.
        - **Characters:** Manage the lifecycle (creation, updating, deletion) of NPC characters.


    **Sessions Service**  
      - **Purpose:** Manages player sessions to maintain game context and track interactions.


    Overall, this specification serves as a detailed guide to leveraging NPC
    Builder’s services—empowering developers to build rich, interactive
    experiences while efficiently managing game contexts and entities.
        _You must stick to the data structure defined, otherwise you may encounter unhandled errors_


    **Please check the schemas of each request to find the allowed values for
    certain properties.**


    _Technical Limitations: Character's knowledge and relationships updating and
    deleting are not available through the API. They must be managed through our
    app's frontend._
