to11ai-sdk 0.5.0

Python SDK for the to11.ai platform

to11ai-sdk

Python SDK for to11.ai — the AI engineering platform for prompt management, tracing, and evals.

Installation

pip install to11ai-sdk
# or with uv
uv add to11ai-sdk

Getting started

from to11ai_sdk import create_client

client = create_client(
    base_url="https://api.to11.ai",
    api_key="...",
)

result = client.prompts.resolve(
    project_id="proj_abc123",
    slug="chat-system-prompt",
    labels=["production"],
    variables={"user_name": "Alice"},
)

print(result.rendered.text)  # "Hello, Alice!"

Features

• Prompt resolution with label-based version selection and Liquid template rendering
• Project label registry CRUD, reverse-lookup, and immutable event history
• Typed errors for auth, rate limiting, validation, and network failures
• Compatible with Python 3.10+

Project label registry

The project label registry is the source of truth for which labels exist on a project. Strict-mode projects reject move_label calls for labels that are not in the registry; the SDK surfaces those as a typed PromptLabelNotRegisteredError.

from to11ai_sdk import create_client, PromptLabelNotRegisteredError

client = create_client(base_url="https://api.to11.ai", api_key="...")

# Register a new label
client.prompts.create_project_label(
    project_id="proj_abc123",
    label="staging",
    is_default=False,
    description="rolling staging pointer",
    display_color="amber",
)

# List active labels
labels = client.prompts.list_project_labels(project_id="proj_abc123")

# List prompts currently pointed at by a label
usages = client.prompts.list_project_label_usages(
    project_id="proj_abc123", label="production",
)

# Inspect the immutable move history at any scope
events = client.prompts.list_label_events(
    scope="project", project_id="proj_abc123", limit=50,
)

# Strict-mode-friendly move
try:
    client.prompts.move_label(
        project_id="proj_abc123",
        prompt_id="prompt_xyz",
        label="production",
        version_id="ver_42",
        reason="promote to production",
    )
except PromptLabelNotRegisteredError as exc:
    # exc.project_id, exc.label carry the structured payload
    print(f"Register {exc.label!r} first")

update_project_label(description=None) means "leave unchanged"; pass description="" to clear it.
