Load Statsig data to DuckDB

Statsig provides APIs for managing feature gates, experiments, and dynamic configurations, as well as logging events and project administration via a Console API. Everything needed to build a working Statsig → 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 Statsig 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 Statsig 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 Statsig 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.

Statsig API at a glance

These values come from the Statsig API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the Statsig API?

All requests require an API key passed in the request header. The Console API requires the 'STATSIG-API-KEY' header, while the HTTP API for client/server interactions uses the 'statsig-api-key' header.

1. Get your credentials

1. Sign in to the Statsig Console at https://console.statsig.com. 2. Navigate to Project Settings in the sidebar. 3. Select Keys & Environments (or API Keys). 4. Click the button to generate a new key (e.g., Generate New Key or Create). 5. Select the appropriate key type (Console API Key is required for management/CRUD operations) and configure the desired permissions (read-only vs. read/write). 6. Copy the generated API key immediately, as it may not be visible again.

2. Add them to .dlt/secrets.toml

Copy
[sources.statsig_source]
console_api_key = "your_console_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 Statsig data can I load into DuckDB?

These are the Statsig endpoints dlt can load into DuckDB:

---

How do I load only new Statsig records?

Statsig exposes after on console/v1/logs, so dlt can request only the records that changed since the last run. Set it as the cursor_path and dlt tracks the high-water mark for you between runs.

Copy
{"name": "logs", "endpoint": {
    "path": "console/v1/logs",
    "data_selector": "events",
    "incremental": {"cursor_path": "after", "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 Statsig pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading /check_gate and /log_event from the Statsig API into DuckDB:

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

@dlt.source
def statsig_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://statsigapi.net (Console API); https://api.statsig.com (HTTP API)",
            "auth": {"type": "api_key", "api_key": api_key, "name": "statsig-api-key", "location": "header"},
        },
        "resources": [
            {"name": "logs", "endpoint": {"path": "console/v1/logs", "data_selector": "events"}},
            {"name": "gates", "endpoint": {"path": "console/v1/gates"}}
        ],
    }
    yield from rest_api_resources(config)


def load_statsig_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="statsig_pipeline",
        destination="duckdb",
        dataset_name="statsig_data",
    )
    load_info = pipeline.run(statsig_source())
    print(load_info)


if __name__ == "__main__":
    load_statsig_to_duckdb()

Run it with python statsig_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 Statsig 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("statsig_pipeline").dataset()
df = data.gates.df()
print(df.head())

SQL:

Copy
SELECT * FROM statsig_data.gates LIMIT 10;

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

---

How do I deploy the Statsig 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 Statsig 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 Statsig 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.
