DomainTools Python API Docs | dltHub

The Iris Enrich API provides high-volume domain enrichment for SIEM and SOAR platforms, offering automated context addition at scale. It supports multiple authentication methods and is part of DomainTools Enterprise accounts. The REST API base URL is https://api.domaintools.com/v1/iris-enrich/ and Header, Open‑key, or HMAC‑signed authentication (X‑Api‑Key or signed/open‑key supported).

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 pip install "dlt[workspace]" and start loading DomainTools data in under 10 minutes.

What data can I load from DomainTools?

Here are some of the endpoints you can load from DomainTools:

---

How do I authenticate with the DomainTools API?

DomainTools Iris supports header API key authentication using the X‑Api‑Key header and also supports Open‑Key (api_username + api_key in query) and HMAC‑signed requests; HTTPS is required and HMAC (SHA‑256) is recommended.

1. Get your credentials

1. Contact DomainTools Sales/Support to provision Iris API access as part of an Enterprise account.
2. In the DomainTools account dashboard, generate an API key (api_key) and note your api_username.
3. Optionally configure HMAC signing credentials (use the same api_key) if signed requests are desired.
4. Ensure the Iris Enrich service is enabled for your account.

2. Add them to .dlt/secrets.toml

Copy
[sources.domain_tools_source]
api_key = "YOUR_API_KEY"

dlt reads this automatically at runtime — never hardcode tokens in your pipeline script. For production environments, see setting up credentials with dlt for environment variable and vault-based options.

How do I set up and run the pipeline?

Set up a virtual environment and install dlt:

Copy
uv venv && source .venv/bin/activate
uv pip install "dlt[workspace]"

1. Install the dlt AI Workbench:

Copy
dlt 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
dlt ai toolkit rest-api-pipeline install

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 DomainTools 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
python domain_tools_pipeline.py

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

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

Inspect your pipeline and data:

Copy
dlt pipeline domain_tools_pipeline 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 iris_enrich and iris_enrich_post from the DomainTools 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 domain_tools_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.domaintools.com/v1/iris-enrich/",
            "auth": {
                "type": "api_key",
                "api_key": api_key,
            },
        },
        "resources": [
            {"name": "iris_enrich", "endpoint": {"path": "iris-enrich/", "data_selector": "response.results"}},
            {"name": "enrich_missing_domains", "endpoint": {"path": "iris-enrich/", "data_selector": "response.missing_domains"}}
        ],
    }
    yield from rest_api_resources(config)


def get_data() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="domain_tools_pipeline",
        destination="duckdb",
        dataset_name="domain_tools_data",
    )
    load_info = pipeline.run(domain_tools_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("domain_tools_pipeline").dataset()
sessions_df = data.iris_enrich.df()
print(sessions_df.head())

SQL (DuckDB example):

Copy
SELECT * FROM domain_tools_data.iris_enrich LIMIT 10;

In a marimo or Jupyter notebook:

Copy
import dlt

data = dlt.pipeline("domain_tools_pipeline").dataset()
data.iris_enrich.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 DomainTools 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.
