Character Crafting APIs

Create and configure AI characters with Convai’s Character Crafting APIs to define their personality, behavior, knowledge and more.

The Character Crafting APIs give developers full control over how an AI character is designed, configured, and evolved. These APIs serve as the foundation of your character’s identity — defining its personality, behavior, knowledge, and narrative consistency across all interactions.

With these APIs, you can:

• Create and manage characters — define character metadata such as name, description, language.

• Configure AI settings through the Core AI Setting API, including model selection, temperature.

• Build and maintain Knowledge Banks — upload, update, and organize documents that form the character’s domain knowledge.

• Develop backstories using the Backstory API, providing depth and continuity to your characters.

• Design narrative elements via the Narrative Design API to create immersive storylines and world-building connections.

• Define and manage actions (gestures, movements, or environment-specific behaviors) using the Action API.

• Access language and voice options via the Language List and Voice List APIs, allowing multilingual and voice-customized character experiences.

• Retrieve and manage character lists and versions through the Character List API, ensuring your production characters stay organized and versioned properly.

• Evaluate and refine your characters’ responses and performance using the Evaluation API.

Together, these APIs let you shape a character’s core intelligence, emotional tone, and knowledge framework, ensuring a consistent, believable personality in every conversation.
