AI Agent
AI Agent is for scenarios where an LLM should answer and call other nodes as tools: databases, APIs, search. It is the same agent as in the scenario builder: the model builds a reply, runs connected tool nodes, and keeps conversation context with Session ID.
Plug and Play (PnP) billing
This is a PnP (Plug and Play) node: Latenode meters usage and charges PnP tokens on top of execution credits (1 PnP token = $1). You don't need your own API key; the price depends on the selected model and is shown in the node settings.
Documentation
The node's fields, tool-calling mechanics, and example scenarios are covered in detail on dedicated pages:
- AI Agent Node: all fields, Function Calling, connecting tools,
fromAIAgent(), and ready-made examples - Tool Design for AI Agents: how to name and describe tools for the agent
- Agent Design Foundations: how to design agent behavior
- AI Agent Examples: ready-to-use agent scenarios
