Load Statsmodels data to DuckDB

Statsmodels is a Python module that provides classes and functions for the estimation of various statistical models, running hypothesis tests, and exploring data, but it does not natively provide a public REST API for data access. Everything needed to build a working Statsmodels → DuckDB pipeline is on this page: the API's base URL, authentication, endpoints, pagination and incremental field — plus a prompt that hands the whole job to your coding agent.

Build your Statsmodels to DuckDB pipeline

Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.

PromptCopy prompt
Run uvx dlthub-init@latest to build a pipeline from Statsmodels to DuckDB and run it on dltHub

That scaffolds a dltHub workspace and installs the dltHub AI harness — the project rules, the secrets-management skill, and the dlt MCP server your agent needs to work safely. From there it reads the Statsmodels API, proposes the endpoints to load, then writes, runs and validates the pipeline while you review rather than type. Credentials are inspected through MCP tools, so your agent never reads secrets.toml itself. How the LLM-native workflow works →

Prefer to write it yourself? Every fact the agent uses is below.

Statsmodels API at a glance

These values come from the Statsmodels API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the Statsmodels API?

The statsmodels library itself is a Python package and does not provide a formal REST API. If using a dlt source implementation as a wrapper, authentication typically requires a Bearer token provided via an access_token parameter.

1. Get your credentials

Statsmodels is a Python library for statistical modeling and does not provide a public REST API for data access; the term API in the context of Statsmodels refers to its Python import interface (e.g., statsmodels.api). If you are using a third-party service that provides a REST wrapper for Statsmodels, refer to that specific provider's documentation for credential setup. The dlt documentation example suggesting a Statsmodels REST API is a conceptual illustration or refers to a custom implementation rather than an official Statsmodels feature.

2. Add them to .dlt/secrets.toml

Copy
[sources.statsmodels_source]
api_key = "your_api_key_here"

dlt reads this file automatically at runtime. With the harness, the setup-secrets skill prompts you for the values and never handles the raw credential in chat. For production, see setting up credentials with dlt.

What Statsmodels data can I load into DuckDB?

These are the Statsmodels endpoints dlt can load into DuckDB:

---

How do I load only new Statsmodels records?

The Statsmodels API reference does not document a timestamp or sequence field for these endpoints, so there is nothing to advertise here as verified. Pick a field from the endpoints table above that increases with every write, then set it as the cursor_path.

Copy
{"name": "ols", "endpoint": {
    "path": "OLS",
    # Replace with a field that increases on every write.
    "incremental": {"cursor_path": "REPLACE_ME", "initial_value": "2024-01-01T00:00:00Z"},
}}

On the first run dlt loads everything from initial_value; on every run after that it requests only what changed and appends with write_disposition="merge" if you set a primary key. See incremental loading.

What does the generated Statsmodels pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading api and OLS from the Statsmodels API into DuckDB:

Copy
import dlt
from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources

@dlt.source
def statsmodels_source(access_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://www.statsmodels.org/api/",
            "auth": {"type": "bearer", "token": access_token},
        },
        "resources": [
            {"name": "ols", "endpoint": {"path": "OLS"}},
            {"name": "tsa", "endpoint": {"path": "tsa/api"}}
        ],
    }
    yield from rest_api_resources(config)


def load_statsmodels_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="statsmodels_pipeline",
        destination="duckdb",
        dataset_name="statsmodels_data",
    )
    load_info = pipeline.run(statsmodels_source())
    print(load_info)


if __name__ == "__main__":
    load_statsmodels_to_duckdb()

Run it with python statsmodels_pipeline.py. The agent iterates on this until it loads cleanly — you review and approve, rather than write it from scratch.

How do I query Statsmodels data in DuckDB?

dlt creates one table per resource. Query the loaded data with Python or SQL — or ask your agent to, through the MCP server's execute_sql_query tool.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("statsmodels_pipeline").dataset()
df = data.ols.df()
print(df.head())

SQL:

Copy
SELECT * FROM statsmodels_data.ols LIMIT 10;

See querying your data with dataset and exploring it in marimo notebooks.

---

How do I deploy the Statsmodels to DuckDB pipeline in production?

The pipeline runs locally, which is ideal for prototyping and one-off analysis. When you need it on a schedule, monitored on every load, and shared with your team, deploy the same dlt code on the dltHub platform — no infrastructure to maintain. The prompt above already ends with "run it on dltHub", so your agent can take it there directly.

• Deploy & schedule — run the pipeline as a managed job with automatic retries.
• Monitor — observable job queues, alerting, and load metrics for every run.
• Transform — promote raw Statsmodels loads into governed, documented models.
• Visualize & share — explore data in notebooks and publish live dashboards instead of static screenshots.

What other destinations can I load Statsmodels data to?

dlt loads into any of these — only the destination argument changes:

Set dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. On the dltHub platform the same pipeline runs against a managed Iceberg lakehouse. See the full destinations list.
