Python Zeroconf Python API Docs | dltHub

Zeroconf-api-service provides a RESTful interface to browse and register mDNS/DNS-SD services in a local network for environments that cannot access UDP multicast natively. The REST API base URL is http://localhost:15051 and no authentication required.

dlt is an open-source Python library that handles authentication, pagination, and schema evolution automatically. dlthub provides AI context files that enable code assistants to generate production-ready pipelines. Install with uv add "dlt[hub]" and start loading Python Zeroconf data in under 10 minutes.

What data can I load from Python Zeroconf?

Here are some of the endpoints you can load from Python Zeroconf:

---

How do I authenticate with the Python Zeroconf API?

The documentation for these community-developed wrapper services does not specify an authentication mechanism, indicating that requests are typically sent without credentials.

No credentials required. The Python Zeroconf API is public, so there is nothing to obtain and nothing to add to .dlt/secrets.toml — the pipeline above runs as written.

---

How do I set up and run the pipeline?

Set up a virtual environment and install dlt:

Copy
uv init
uv add "dlt[hub]"

1. Install the dlt AI harness:

Copy
uv run dlthub ai init --agent <your-agent> # <agent>: claude | cursor | codex

This installs project rules, a secrets management skill, appropriate ignore files, and configures the dlt MCP server for your agent. Learn more →

2. Install the rest-api-pipeline toolkit:

Copy
uv run dlthub ai toolkit install rest-api-pipeline

This loads the skills and context about dlt the agent uses to build the pipeline iteratively, efficiently, and safely. The agent uses MCP tools to inspect credentials — it never needs to read your secrets.toml directly. Learn more →

3. Start LLM-assisted coding:

Use /find-source to load data from the Python Zeroconf API into DuckDB.

The rest-api-pipeline toolkit takes over from here — it reads relevant API documentation, presents you with options for which endpoints to load, and follows a structured workflow to scaffold, debug, and validate the pipeline step by step.

4. Run the pipeline:

Copy
uv run python python_zeroconf_pipeline.py

If everything is configured correctly, you'll see output like this:

Copy
Pipeline python_zeroconf_pipeline load step completed in 0.26 seconds
1 load package(s) were loaded to destination duckdb and into dataset python_zeroconf_data
The duckdb destination used duckdb:/python_zeroconf.duckdb location to store data
Load package 1749667187.541553 is LOADED and contains no failed jobs

Inspect your pipeline and data:

Copy
uv run dlthub show

This opens the Pipeline Dashboard where you can verify pipeline state, load metrics, schema (tables, columns, types), and query the loaded data directly.

Python pipeline example

This example loads /zeroconf (GET for listing services) and /zeroconf (POST for registering services) from the Python Zeroconf API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:

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

@dlt.source
def python_zeroconf_source():
    config: RESTAPIConfig = {
        "client": {
            "base_url": "http://localhost:15051",
        },
        "resources": [
            {"name": "zeroconf_services", "endpoint": {"path": "/"}},
            {"name": "service_info", "endpoint": {"path": "/"}}
        ],
    }
    yield from rest_api_resources(config)


def get_data() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="python_zeroconf_pipeline",
        destination="duckdb",
        dataset_name="python_zeroconf_data",
    )
    load_info = pipeline.run(python_zeroconf_source())
    print(load_info)

To add more endpoints, append entries from the resource table to the "resources" list using the same name, path, and data_selector pattern.

---

How do I query the loaded data?

Once the pipeline runs, dlt creates one table per resource. You can query with Python or SQL.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("python_zeroconf_pipeline").dataset()
sessions_df = data.zeroconf_services.df()
print(sessions_df.head())

SQL (DuckDB example):

Copy
SELECT * FROM python_zeroconf_data.zeroconf_services LIMIT 10;

In a marimo or Jupyter notebook:

Copy
import dlt

data = dlt.pipeline("python_zeroconf_pipeline").dataset()
data.zeroconf_services.df().head()

See how to explore your data in marimo Notebooks and how to query your data in Python with dataset.

---

What destinations can I load Python Zeroconf data to?

dlt supports loading into any of these destinations — only the destination parameter changes:

Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.
