Restpack Python API Docs | dltHub

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

Last updated:

Restpack's HTML to PDF API converts web pages into PDF documents. The latest version is v7. For older versions, refer to v4, v2, and v1 documentation. The REST API base URL is https://restpack.io/api/html2pdf and All requests require an access token supplied via the access_token query parameter or the X-Access-Token header..

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 Restpack data in under 10 minutes.


What data can I load from Restpack?

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

ResourceEndpointMethodData selectorDescription
convert_v7convertGETCreate and return a PDF document (v7)
convert_v4convertGETCreate and return a PDF document (v4)
convert_v2convertGETCreate and return a PDF document (v2)
usageusageGETusageRetrieve account usage statistics
convert_v7_postconvertPOSTCreate a PDF using a JSON or URL‑encoded body (v7)
convert_v4_postconvertPOSTCreate a PDF using a JSON or URL‑encoded body (v4)
convert_v2_postconvertPOSTCreate a PDF using a JSON or URL‑encoded body (v2)

How do I authenticate with the Restpack API?

Provide the Direct Access Token either as the access_token querystring parameter or in the X-Access-Token header for every request.

1. Get your credentials

  1. Log in to your Restpack account dashboard.
  2. Navigate to the User Tokens or API Tokens section.
  3. Click Create New Token (or similar).
  4. Copy the generated token; it will be used as the access_token query parameter or the X-Access-Token header.

2. Add them to .dlt/secrets.toml

[sources.restpack_html_to_pdf_source] api_key = "your_access_token_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 venv && source .venv/bin/activate uv pip install "dlt[workspace]"

1. Install the dlt AI Workbench:

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:

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 Restpack 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:

python restpack_html_to_pdf_pipeline.py

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

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

Inspect your pipeline and data:

dlt pipeline restpack_html_to_pdf_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 convert and usage from the Restpack 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 restpack_html_to_pdf_source(access_token=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://restpack.io/api/html2pdf", "auth": { "type": "api_key", "api_key": access_token, }, }, "resources": [ {"name": "convert", "endpoint": {"path": "convert"}}, {"name": "usage", "endpoint": {"path": "usage", "data_selector": "usage"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="restpack_html_to_pdf_pipeline", destination="duckdb", dataset_name="restpack_html_to_pdf_data", ) load_info = pipeline.run(restpack_html_to_pdf_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("restpack_html_to_pdf_pipeline").dataset() sessions_df = data.convert.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM restpack_html_to_pdf_data.convert LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("restpack_html_to_pdf_pipeline").dataset() data.convert.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 Restpack 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.
