LangWatch integrates with OpenAI Agents through OpenInference instrumentation to monitor agent execution, LLM calls, and tool usage.

Installation

Usage

The LangWatch API key is configured by default via the LANGWATCH_API_KEY environment variable.
Use the OpenInference instrumentation for OpenAI Agents by passing OpenAIAgentsInstrumentor to langwatch.setup().
The OpenAIAgentsInstrumentor automatically captures agent activities, LLM calls, and tool usage. Use @langwatch.trace() to create a parent trace under which agent operations will be nested.
