🧑‍💻 Developer Experience

Python API

Use ZeroZen programmatically in your own applications:

from zerozen import agents

# Simple agent usage
result = agents.run_sync(
    "Find emails from GitHub about security issues", tools=["search_gmail"], max_turns=3
)
print(result)

# Advanced usage with specific tools
result = agents.run_sync(
    "What's my schedule conflicts next week?",
    tools=["list_calendar_events", "search_gmail"],
    model="gpt-4o",  # Optional model override
)

Custom Integrations

from zerozen.integrations.google import GmailService, load_user_credentials

# Load your saved credentials
creds = load_user_credentials("credentials.my_google_account.json")

# Direct tool usage
gmail = GmailService(creds)
messages = gmail.search_messages(query="from:github.com", limit=10)

# Your custom logic here...

Backend Integration

Perfect for server applications:

from zerozen.integrations.google import CredentialRecord, UserProviderMetadata, UserInfo

# Create from your database/API
user_creds = CredentialRecord(
    access_token="ya29.xxx",
    user_provider_metadata=UserProviderMetadata(
        refresh_token="1//xxx",
        scope=(
            "openid "
            "https://www.googleapis.com/auth/gmail.readonly "
