HARPA AI Python API Docs | dltHub

Build a HARPA AI-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.

Last updated:

HARPA AI is a browser-orchestration and web-automation platform that allows users to run scraping, search, and AI actions on connected browser nodes via a Grid REST API. The REST API base URL is https://api.harpa.ai/api/v1/grid and all requests require a Bearer token.

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 HARPA AI data in under 10 minutes.


What data can I load from HARPA AI?

Here are some of the endpoints you can load from HARPA AI:

ResourceEndpointMethodData selectorDescription
scrape/api/v1/gridPOSTScrape web pages or elements (use action: 'scrape').
serp/api/v1/gridPOSTRun web searches (use action: 'serp').
command/api/v1/gridPOSTRun a named AI command (use action: 'command').
prompt/api/v1/gridPOSTRun a custom AI prompt (use action: 'prompt').
ping/api/v1/gridPOSTCheck Node availability (use action: 'ping').

How do I authenticate with the HARPA AI API?

All requests require an 'Authorization' header with a Bearer token. The token is obtained from the HARPA AI Chrome extension's AUTOMATE tab.

1. Get your credentials

  1. Install the HARPA AI Chrome extension from the official store (get.harpa.ai). 2. Open the HARPA AI extension in your browser. 3. Navigate to the AUTOMATE tab within the extension interface. 4. Locate the section for the API key, generate it if necessary, and copy the key. Note: For security reasons, the key is typically displayed only once, so store it securely.

2. Add them to .dlt/secrets.toml

[sources.harpa_ai_source] api_key = "your_harpa_api_key_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 HARPA AI 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 harpa_ai_pipeline.py

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

Pipeline harpa_ai_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset harpa_ai_data The duckdb destination used duckdb:/harpa_ai.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 api/v1/grid (the primary REST API endpoint for browser automation tasks) and the general base URL https://api.harpa.ai/api/v1/grid used for POST requests. from the HARPA AI 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 harpa_ai_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.harpa.ai/api/v1/grid", "auth": {"type": "bearer", "token": api_key}, }, "resources": [ {"name": "scrape", "endpoint": {"path": "api/v1/grid"}}, {"name": "serp", "endpoint": {"path": "api/v1/grid"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="harpa_ai_pipeline", destination="duckdb", dataset_name="harpa_ai_data", ) load_info = pipeline.run(harpa_ai_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("harpa_ai_pipeline").dataset() sessions_df = data.grid.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM harpa_ai_data.grid LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("harpa_ai_pipeline").dataset() data.grid.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 HARPA AI data to?

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

DestinationExample 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.
