Load Stb Tester data to DuckDB

Stb-tester is a test automation platform that provides a REST API for controlling Stb-tester nodes and managing test jobs programmatically. Everything needed to build a working Stb Tester → 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 Stb Tester 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 Stb Tester 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 Stb Tester 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.

Stb Tester API at a glance

These values come from the Stb Tester API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the Stb Tester API?

Authentication is performed by including the generated access token in the 'Authorization' HTTP header of every request.

1. Get your credentials

To obtain an access token for the Stb-tester REST API, log into your Stb-tester Portal instance in your web browser. Click on the user menu located in the top right corner of the dashboard, and select 'Generate new access token'. You can manage and revoke existing tokens from this same menu. This token must be included in the 'Authorization' HTTP header for all REST API requests.

2. Add them to .dlt/secrets.toml

Copy
[sources.stb_tester_source]
api_token = "REPLACE_ME"

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 Stb Tester data can I load into DuckDB?

These are the Stb Tester endpoints dlt can load into DuckDB:

---

How do I load only new Stb Tester records?

The Stb Tester 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": "test_results", "endpoint": {
    "path": "api/v2/results",
    # 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 Stb Tester pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading /api/v2/run_tests and /api/v2/results from the Stb Tester API into DuckDB:

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

@dlt.source
def stb_tester_source(api_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://<portal_name>.stb-tester.com/api/v2",
            "auth": {"type": "bearer", "token": api_token},
        },
        "resources": [
            {"name": "test_results", "endpoint": {"path": "api/v2/results"}},
            {"name": "nodes", "endpoint": {"path": "api/v2/nodes"}}
        ],
    }
    yield from rest_api_resources(config)


def load_stb_tester_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="stb_tester_pipeline",
        destination="duckdb",
        dataset_name="stb_tester_data",
    )
    load_info = pipeline.run(stb_tester_source())
    print(load_info)


if __name__ == "__main__":
    load_stb_tester_to_duckdb()

Run it with python stb_tester_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 Stb Tester 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("stb_tester_pipeline").dataset()
df = data.test_results.df()
print(df.head())

SQL:

Copy
SELECT * FROM stb_tester_data.test_results LIMIT 10;

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

How do I deploy the Stb Tester 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 Stb Tester 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 Stb Tester 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.
