Signet + OpenAI Agents SDK Example

Add cryptographic signing to every tool call in the OpenAI Agents SDK.

Install

pip install signet-auth openai-agents

Quick Start

from agents import Agent, Runner, function_tool
from signet_auth import SigningAgent
from signet_auth.openai_agents import SignetTracingProcessor

signer = SigningAgent.create("openai-bot", owner="team")

@function_tool
def get_weather(city: str) -> str:
    return f"Sunny in {city}"

agent = Agent(name="assistant", tools=[get_weather])

# Add Signet tracing — every tool call is signed
with Runner.run(agent, input="Weather in Tokyo?") as result:
    processor = SignetTracingProcessor(signer)
    processor.process(result)
    print(result.final_output)

Verify
