Treq Python API Docs | dltHub
Build a Treq-to-database pipeline in Python using dlt with AI Workbench support for Claude Code, Cursor, and Codex.
Last updated:
Treq is a high-level HTTP client API built on Twisted. It provides functions like request for making HTTP requests. The latest version is 25.5.0. The REST API base URL is `` and no built-in API; supports HTTP Basic auth via credentials or arbitrary Authorization headers.
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 Treq data in under 10 minutes.
What data can I load from Treq?
Here are some of the endpoints you can load from Treq:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| treq_get | user-specified_url | GET | Make a GET request to any URL; response parsing depends on the target service | |
| treq_post | user-specified_url | POST | Make a POST request to any URL | |
| treq_put | user-specified_url | PUT | Make a PUT request to any URL | |
| treq_delete | user-specified_url | DELETE | Make a DELETE request to any URL | |
| treq_patch | user-specified_url | PATCH | Make a PATCH request to any URL |
How do I authenticate with the Treq API?
treq is a client library; supply auth by passing an auth tuple (username, password) to requests or by setting Authorization headers (e.g., 'Authorization: Bearer '). Use treq.auth.add_basic_auth(agent, username, password) to wrap an agent for HTTP Basic auth.
1. Get your credentials
Obtain credentials from the service you are calling (e.g., your API provider). For HTTP Basic use the username and password issued by the provider; for bearer tokens create/generate a token in the provider's dashboard and supply it as an 'Authorization: Bearer ' header in requests.
2. Add them to .dlt/secrets.toml
[sources.treq_source] auth = ("username_here", "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 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 Treq 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 treq_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline treq_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset treq_data The duckdb destination used duckdb:/treq.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs
Inspect your pipeline and data:
dlt pipeline treq_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 treq_get and treq_post from the Treq 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 treq_source(auth=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "", "auth": { "type": "http_basic", "password": auth, }, }, "resources": [ {"name": "treq_get", "endpoint": {"path": "(user-specified URL, e.g., "https://api.example.com/resource")"}}, {"name": "treq_post", "endpoint": {"path": "(user-specified URL)"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="treq_pipeline", destination="duckdb", dataset_name="treq_data", ) load_info = pipeline.run(treq_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("treq_pipeline").dataset() sessions_df = data.treq_get.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM treq_data.treq_get LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("treq_pipeline").dataset() data.treq_get.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 Treq 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.
