Socrata Python API Docs | dltHub

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

Last updated:

The Socrata REST API follows CRUD operations, uses SoQL for querying, and endpoints are structured with /api/v3/views/IDENTIFIER/query.json. The REST API base URL is https://{domain}/api/v3 and All requests use HTTP Basic authentication with an API key ID and secret..

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 Socrata data in under 10 minutes.


What data can I load from Socrata?

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

ResourceEndpointMethodData selectorDescription
catalog/api/v3/catalogGETresultsList of available datasets.
dataset_query/api/v3/views/{identifier}/query.jsonGETrowsExecute a query on a dataset and return rows.
dataset_export_csv/api/v3/views/{identifier}/export.csvGETDownload the dataset as CSV.
metadata/api/v3/views/{identifier}.jsonGETmetadataRetrieve metadata for a dataset.
group_views/api/v3/groups/{group_id}/views.jsonGETviewsList datasets belonging to a group.

How do I authenticate with the Socrata API?

Use HTTP Basic authentication; provide the API key ID as the username and the secret as the password (or use a username/password). Include an X-App-Token header if an application token is required.

1. Get your credentials

  1. Log in to https://dev.socrata.com with your Socrata account.
  2. Click on "My Account" then select "API Keys".
  3. Press "Create New Key".
  4. Copy the displayed keyId and keySecret; store them securely.
  5. Use the keyId as the username and the keySecret as the password for HTTP Basic authentication.

2. Add them to .dlt/secrets.toml

[sources.socrata_source] api_key = "your_api_key_id" api_secret = "your_api_key_secret"

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 Socrata 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 socrata_pipeline.py

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

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

Inspect your pipeline and data:

dlt pipeline socrata_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 dataset_query and dataset_export_csv from the Socrata 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 socrata_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://{domain}/api/v3", "auth": { "type": "http_basic", "api_key": api_key, }, }, "resources": [ {"name": "dataset_query", "endpoint": {"path": "api/v3/views/{identifier}/query.json", "data_selector": "rows"}}, {"name": "dataset_export_csv", "endpoint": {"path": "api/v3/views/{identifier}/export.csv"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="socrata_pipeline", destination="duckdb", dataset_name="socrata_data", ) load_info = pipeline.run(socrata_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("socrata_pipeline").dataset() sessions_df = data.dataset_query.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM socrata_data.dataset_query LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("socrata_pipeline").dataset() data.dataset_query.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 Socrata 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.
