openapi: 3.0.1 info: title: Colossyan Avatars Voices API description: REST API for the Colossyan AI avatar and video generation platform. Generate studio-quality videos from a script combined with AI avatars and voices via asynchronous video-generation jobs, list avatars/presenters and voices, create custom Instant avatars, generate from templates, and receive completion notifications via webhook callbacks. All requests and responses use JSON. API access requires a Business or Enterprise plan; the API token is found in the workspace Settings. Endpoint paths, request fields, and response fields below reflect Colossyan's public documentation (docs.colossyan.com); exact JSON schemas are not fully published, so request and response bodies are described as free-form objects where the schema is not documented. termsOfService: https://www.colossyan.com/terms-and-conditions contact: name: Colossyan Support url: https://www.colossyan.com/contact version: '1.0' servers: - url: https://app.colossyan.com/api/v1 description: Stable v1 API - url: https://app.colossyan.com/api description: Experimental (non-versioned) endpoints security: - bearerAuth: [] tags: - name: Voices description: List available AI voices. paths: /assets/voices: get: operationId: listVoices tags: - Voices summary: List voices description: Returns the AI voices available for narration across the platform's supported languages. responses: '200': description: A list of voices. content: application/json: schema: type: array items: $ref: '#/components/schemas/Voice' components: schemas: Voice: type: object description: An AI voice available for narration. properties: speakerId: type: string description: Identifier used as speakerId on tracks during video generation. name: type: string language: type: string securitySchemes: bearerAuth: type: http scheme: bearer description: Bearer token authentication.
