Simple python client for exctracting data from the Dune Analytics API

spice 🌶️

Simple python client for extracting data from the Dune Analytics API

Goals of spice:

• simple, no OOP, entire api is just one function
• support both sync and async workflows
• tight integration with polars

To discuss spice, head to the Paradigm Data Tools Telegram channel.

Installation

pip install dune_spice

Examples

Can either use the sync workflow or async workflow. Each workflow has only one function.

See API Reference below for the full list of query function arguments.

Sync Workflow

import spice

# get most recent query results using query id
df = spice.query(21693)

# get most recent query results using query url
df = spice.query('https://dune.com/queries/21693')

# perform new query execution and get results
df = spice.query(query, refresh=True)

# get query results for input parameters
df = spice.query(query, parameters={'network': 'ethereum'})

# perform new query execution, but do not wait for result
execution = spice.query(query, poll=False)

# get results of previous execution
df = spice.query(execution)

Async Workflow

The async API is identical to the sync API as above, just add async_ prefix.

df = await spice.async_query(21693)
df = await spice.async_query('https://dune.com/queries/21693')
df = await spice.async_query(query, refresh=True)
df = await spice.async_query(query, parameters={'network': 'ethereum'})
execution = await spice.async_query(query, poll=False)
df = await spice.async_query(execution)

API Reference

Types

from typing import Any, Literal, Mapping, Sequence, TypedDict
import polars as pl

# query is an int id or query url
Query = int | str

# execution performance level
Performance = Literal['medium', 'large']

# execution
class Execution(TypedDict):
    execution_id: str

Functions

These functions are accessed as spice.query() and spice.aysnc_query().

def query(
    query_or_execution: Query | Execution,
    *,
    verbose: bool = True,
    refresh: bool = False,
    parameters: Mapping[str, Any] | None = None,
    api_key: str | None = None,
    performance: Performance = 'medium',
    poll: bool = True,
    poll_interval: float = 1.0,
    limit: int | None = None,
    offset: int | None = None,
    sample_count: int | None = None,
    sort_by: str | None = None,
    columns: Sequence[str] | None = None,
    extras: Mapping[str, Any] | None = None,
    dtypes: Sequence[pl.DataType] | None = None,
) -> pl.DataFrame | Execution:
    """get results of query as dataframe

    # Parameters
    - query_or_execution: query or execution to retrieve results of
    - verbose: whether to print verbose info
    - refresh: trigger a new execution, or just use most recent execution
    - parameters: dict of query parameters
    - api_key: dune api key, otherwise use DUNE_API_KEY env var
    - performance: performance level
    - poll: wait for result as DataFrame, or just return Execution handle
    - poll_interval: polling interval in seconds
    - limit: number of rows to query in result
    - offset: row number to start returning results from
    - sample_count: number of random samples from query to return
    - sort_by: an ORDER BY clause to sort data by
    - columns: columns to retrieve, by default retrieve all columns
    - extras: extra parameters used for fetching execution result
        - examples: ignore_max_datapoints_per_request, allow_partial_results
    - dtypes: dtypes to use in output polars dataframe
    """
    ...

async def async_query(
    # all the same parameters as query()
    ...
) -> pl.DataFrame | Execution:
    """get results of query as dataframe, asynchronously

    ## Parameters
    [see query()]
    """

FAQ

How do I set my Dune API key?

spice looks for a Dune api key in the DUNE_API_KEY environment variable.

Which endpoints does this package support?

spice interacts only with Dune's SQL-related API endpoints, documented here.
