DataForSEO Python API Docs | dltHub
Build a DataForSEO-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.
Last updated:
DataForSEO is a suite of SEO and marketing data APIs that provides access to search engine results, keyword research, and website analysis data. The REST API base URL is https://api.dataforseo.com/ and all requests require a Basic authentication header containing Base64-encoded login and password credentials.
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 DataForSEO data in under 10 minutes.
What data can I load from DataForSEO?
Here are some of the endpoints you can load from DataForSEO:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| serp_tasks | v3/serp/google/organic/task_post | POST | Submit a SERP task | |
| serp_results | v3/serp/google/organic/task_get/$id | GET | tasks | Retrieve SERP task results |
| on_page_pages | v3/on_page/pages | POST | tasks | Retrieve paginated on-page audit pages |
| on_page_links | v3/on_page/links | POST | tasks | Retrieve paginated on-page audit links |
| keywords_data_endpoints | v3/keywords_data/endpoints | GET | tasks | List available keyword data endpoints |
How do I authenticate with the DataForSEO API?
The API uses Basic authentication where the credentials (login
) are encoded in Base64 and passed in the 'Authorization' header as 'Basic <encoded_string>'. No separate authentication call is required.1. Get your credentials
To obtain your API credentials, log in to the DataForSEO dashboard at https://app.dataforseo.com/. Once logged in, navigate to the 'API Access' section, which is accessible via the left-hand navigation menu or the top bar shortcut. This page displays your 'API login' and 'API password'. Note that the API password is generated automatically upon registration and is distinct from your dashboard login password. For security reasons, the API password is only visible on this page for the first 24 hours after registration; if you need it later, use the 'Send by e-mail' option in the dashboard to have your credentials securely sent to your account email address.
2. Add them to .dlt/secrets.toml
[sources.dataforseo_source] dataforseo_api_login = "your_api_login_here" dataforseo_api_password = "your_api_password_here"
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:
uv init uv add "dlt[hub]"
1. Install the dlt AI harness:
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:
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 DataForSEO 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:
uv run python dataforseo_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline dataforseo_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset dataforseo_data The duckdb destination used duckdb:/dataforseo.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs
Inspect your pipeline and data:
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 task_post and task_get from the DataForSEO API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:
import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def dataforseo_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.dataforseo.com/", "auth": {"type": "http_basic", "username": "REPLACE_ME", "password": api_key}, }, "resources": [ {"name": "on_page_pages", "endpoint": {"path": "v3/on_page/pages", "data_selector": "tasks"}}, {"name": "on_page_links", "endpoint": {"path": "v3/on_page/links", "data_selector": "tasks"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="dataforseo_pipeline", destination="duckdb", dataset_name="dataforseo_data", ) load_info = pipeline.run(dataforseo_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):
import dlt data = dlt.pipeline("dataforseo_pipeline").dataset() sessions_df = data.on_page_pages.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM dataforseo_data.on_page_pages LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("dataforseo_pipeline").dataset() data.on_page_pages.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 DataForSEO data to?
dlt supports loading into any of these destinations — only the destination parameter changes:
| Destination | Example value |
|---|---|
| DuckDB (local, default) | "duckdb" |
| PostgreSQL | "postgres" |
| BigQuery | "bigquery" |
| Snowflake | "snowflake" |
| Redshift | "redshift" |
| Databricks | "databricks" |
| Filesystem (S3, GCS, Azure) | "filesystem" |
Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.
