promptic-sdk 0.11.1

Python SDK for the Promptic platform — tracing, API client, and CLI.

Promptic Python SDK

Python SDK and CLI for the Promptic platform — tracing, prompt optimization, and experiment management.

Installation

pip install promptic-sdk

Optional LLM instrumentation

Install extras to auto-instrument specific LLM providers:

pip install promptic-sdk[openai]       # OpenAI
pip install promptic-sdk[anthropic]    # Anthropic
pip install promptic-sdk[langchain]    # LangChain
pip install promptic-sdk[all]          # All providers

Quick start

1. Authenticate

Log in via browser (recommended for local development):

promptic login

This opens your browser for authentication, then auto-selects your workspace. Credentials are saved to ~/.promptic/config.toml.

For CI/CD or headless environments, use an API key instead:

promptic configure
# or set the environment variable:
export PROMPTIC_API_KEY="pk_..."

2. Send traces

import promptic_sdk
from openai import OpenAI

# Initialize tracing (auto-instruments installed LLM libraries)
promptic_sdk.init()

client = OpenAI()

# Tag traces with an AI Component name
with promptic_sdk.ai_component("customer-support-agent"):
    response = client.chat.completions.create(
        model="gpt-4.1-nano",
        messages=[{"role": "user", "content": "Hello!"}],
    )

3. Use the API client

from promptic_sdk import PrompticClient

with PrompticClient() as client:
    # List traces
    traces = client.list_traces(limit=10)

    # Get workspace info
    workspace = client.get_workspace()

    # Manage experiments
    experiment = client.create_experiment(
        ai_component_id="comp_...",
        target_model="gpt-4.1-nano",
        task_type="classification",
        initial_prompt="Classify the following text.",
    )

    # Deploy the best prompt
    client.deploy(component_id="comp_...", experiment_id="exp_...")

    # Fetch a deployed prompt at runtime
    prompt = client.get_deployed_prompt("comp_...")

Tracing

promptic_sdk.init() sets up OpenTelemetry to export spans to the Promptic platform.

Parameter	Description	Default
api_key	Promptic API key (falls back to PROMPTIC_API_KEY)	—
endpoint	Platform URL (falls back to PROMPTIC_ENDPOINT)	https://promptic.eu
auto_instrument	Auto-detect and instrument LLM client libraries	True
service_name	OpenTelemetry service.name resource attribute	—

Auto-detected instrumentors: OpenAI, Anthropic, Google Generative AI, LangChain, Cohere.

Using other OpenTelemetry instrumentors

Since Promptic uses standard OpenTelemetry under the hood, you can add any OTel-compatible instrumentor alongside the auto-detected ones. Just call promptic_sdk.init() first, then instrument manually:

import promptic_sdk
from opentelemetry.instrumentation.requests import RequestsInstrumentor
from opentelemetry.instrumentation.sqlalchemy import SQLAlchemyInstrumentor

promptic_sdk.init()

# Add any OpenTelemetry instrumentor — spans will be exported to Promptic
RequestsInstrumentor().instrument()
SQLAlchemyInstrumentor().instrument(engine=engine)

This works with any package from the opentelemetry-python-contrib ecosystem (HTTP clients, databases, web frameworks, etc.). All spans are exported to the Promptic platform as long as init() has been called.

AI Components

Use ai_component() to tag spans with a component name. The platform links traces to the matching AI Component in your workspace:

with promptic_sdk.ai_component("my-component"):
    # All LLM calls here are tagged
    ...

API client

Both a sync (PrompticClient) and async (AsyncPrompticClient) client are available. They share the same method signatures and return types.

from promptic_sdk import PrompticClient

with PrompticClient() as client:
    traces = client.list_traces(limit=10)

from promptic_sdk import AsyncPrompticClient

async with AsyncPrompticClient() as client:
    traces = await client.list_traces(limit=10)

Both clients provide typed methods for the full Promptic REST API:

Resource	Methods
Workspace	get_workspace
Traces	list_traces, get_trace, get_stats
Components	list_components, get_component, create_component, delete_component
Experiments	list_experiments, get_experiment, create_experiment, update_experiment, delete_experiment, start_experiment
Observations	list_observations, create_observations, update_observation, delete_observation
Evaluators	list_evaluators, create_evaluators, update_evaluator, delete_evaluator
Iterations	list_iterations, get_iteration, get_best_iteration
Deployments	get_deployment, deploy, undeploy, get_deployed_prompt

The client reads PROMPTIC_API_KEY and PROMPTIC_ENDPOINT from the environment, or accepts them as constructor arguments.

CLI

The promptic CLI mirrors the API client and supports both human-readable tables and --json output.

Configuration

The SDK and CLI resolve configuration in this order:

1. Explicit arguments (api_key=, endpoint=)
2. Environment variables (PROMPTIC_API_KEY, PROMPTIC_ENDPOINT)
3. Config file (~/.promptic/config.toml, written by promptic login or promptic configure)

Variable	Description	Default
PROMPTIC_API_KEY	API key (for tracing & CI/CD)	—
PROMPTIC_ENDPOINT	Platform URL	https://promptic.eu
