AI Agents

What Is an AI Agent API?

AI agents are autonomous systems that use LLMs to plan, execute, and iterate on tasks. Unlike chatbots, they can use tools, browse the web, access files, and orchestrate multi-step workflows.

An AI Agent API gives developers programmatic access to create, manage, and run AI agents. These agents can call functions, retrieve information, use external tools, and execute complex multi-step tasks — all autonomously.

Plugsky's Agent API provides 70+ built-in tools including web search, browser automation, email, file operations, GitHub, Slack, and more. Agents can use any combination of these tools to complete user requests.

Key capabilities include: tool calling and function calling, RAG integration for accessing knowledge bases, persistent memory across conversations, human-in-the-loop approval flows, scheduled task execution, and sub-agent spawning for parallel work.

Building an agent with Plugsky is straightforward. The API is fully OpenAI-compatible, so your existing function-calling code works. Just expand your tool definitions and let the agent orchestrate the workflow.

Try building your first agent in the Plugsky playground — no setup required. The free tier includes agent capabilities with generous rate limits.
