AgentBuilder provides a "Backend-as-a-Service" API, allowing developers to access LLM capabilities directly in frontend apps without backend complexity.
Benefits of Using AgentBuilder APIs
- Securely access LLMs from frontend apps without backend development.
- Visual application design with real-time updates.
- Well-encapsulated LLM APIs.
- Effortlessly switch LLM providers and centrally manage API keys.
- Visual operation: log analysis, annotation, user activity observation.
- Continuous addition of tools, plugins, and knowledge.
How to Use
- Choose an application and find API Access in the left navigation of the Apps section.
- View API documentation and manage credentials for API access.

- Create multiple access credentials for different users or developers. API users can use the AI capabilities provided by the developer, while prompts, knowledge, and tools remain encapsulated.
Best Practice: API keys should be accessed via backend calls, not exposed in frontend code or requests, to prevent abuse or attacks.
Text Generator Application Example
- Used to generate high-quality text (articles, summaries, translations, etc.) by calling the
completion-messagesAPI. - Model parameters and prompt templates are set in the AgentBuilder Prompt Arrangement page.
- Find API documentation and example requests in the API Access section of your application.
