dune-client

What it is and what it does

dune-client is a Python wrapper around Dune Analytics' official REST API, designed to let you run SQL queries against blockchain data and retrieve results programmatically. It handles authentication, query parameterization (text, number, date, enum types), and result formatting—you can fetch results as JSON, CSV, or Pandas DataFrames. The package also supports advanced features like fetching cached results without re-running queries, and for paid subscribers, full CRUD operations to create, update, archive, and manage queries directly from Python.

The library is built on standard HTTP clients (aiohttp and requests) and JSON serialization tools, making it straightforward to integrate into data pipelines, analytics scripts, or automated reporting workflows. It requires Python 3.11 or later and is actively maintained by the Dune Analytics team.

Use it for:

• Run parameterized SQL queries against Ethereum and other blockchain data without leaving Python.
• Fetch cached query results to avoid re-execution costs when data freshness allows.
• Build automated dashboards or reports that pull on-chain metrics into Pandas DataFrames.
• Programmatically manage a library of Dune queries (create, update, archive) as part of a data pipeline.
• Integrate blockchain data retrieval into Python applications that need real-time or periodic on-chain metrics.

Worth the install?

License in practice

Apache License 2.0 is permissive; you can use, modify, and distribute this package freely in commercial and private projects as long as you include the license notice.

Quickstart

pip install dune-client

from dune_client.client import DuneClient
from dune_client.types import QueryParameter
from dune_client.query import QueryBase

dune = DuneClient()
query = QueryBase(name="Sample", query_id=1215383)
results = dune.run_query(query)

Requires a valid DUNE_API_KEY environment variable to authenticate with the Dune Analytics API.

Verify before relying

• Rate limits or throttling behavior on the Dune API when running frequent queries.
• Whether paid subscription features (CRUD operations, query creation) are fully functional in all environments.
• Performance characteristics when handling large result sets or complex parameterized queries.
