AI agent generator — build & deploy autonomous AI agents

An endpoint for building AI agents rather than calling a single model. You describe the agent and the API produces one capable of natural language understanding, decision-making and context-aware responses.

It is aimed at automation platforms, chatbot builders, AI assistants and business intelligence products that need agents as a feature, not a project.

ChatGPT API — GPT-4, o1 and o3 integration

One endpoint onto the OpenAI model family, including GPT-4 and the reasoning models, for chatbots, support automation and workflow tools.

It removes the SDK and key-management step for products that only need the call.
