The OpenAI Agents SDK (openai-agents) is a lightweight framework for building multi-agent workflows with tools, handoffs, and guardrails. Respan gives you full observability over every agent run, LLM generation, tool call, and handoff — and gateway routing to 250+ models.
Create an account at platform.respan.ai and grab an API key. For gateway, also add credits or a provider key.
Run npx @respan/cli setup to set up with your coding agent.
Open the Traces page to see your workflow with agent spans, LLM generations, tool calls, and handoffs.
Set defaults at initialization — these apply to all spans.
Override per-request using a context scope.
Decorators are not required. All agent runs, LLM calls, tool calls, and handoffs are auto-traced by the instrumentor. Use @workflow and @task to add structure when you want to group agent runs into named workflows with nested tasks.
Tool calls are automatically captured as spans with inputs, outputs, and timing.
Agent-to-agent handoffs are traced with full context.
Stream agent responses with real-time text deltas.
