Cloud SQL Admin API v1 Python API Docs | dltHub

Build a Cloud SQL Admin API v1-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.

Last updated:

Cloud SQL Admin API is a service for managing Cloud SQL instances for MySQL, PostgreSQL, and SQL Server. The REST API base URL is https://sqladmin.googleapis.com and supports API key via query parameter or OAuth 2.0 Bearer token via 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 add "dlt[hub]" and start loading Cloud SQL Admin API v1 data in under 10 minutes.


What data can I load from Cloud SQL Admin API v1?

Here are some of the endpoints you can load from Cloud SQL Admin API v1:

ResourceEndpointMethodData selectorDescription
instancesv1/projects/{project}/instancesGETitemsLists instances under a given project.
databasesv1/projects/{project}/instances/{instance}/databasesGETitemsLists databases in the specified Cloud SQL instance.
backup_runsv1/projects/{project}/instances/{instance}/backupRunsGETitemsLists backup runs associated with the instance.
usersv1/projects/{project}/instances/{instance}/usersGETitemsLists users in the specified Cloud SQL instance.
operationsv1/projects/{project}/operationsGETitemsLists operations under a given project.

How do I authenticate with the Cloud SQL Admin API v1 API?

Authentication can be performed using an API key passed as a query parameter or an OAuth 2.0 access token passed in the Authorization header. When using an OAuth 2.0 token, the required header is 'Authorization: Bearer '.

1. Get your credentials

  1. Navigate to the Google Cloud Console (console.cloud.google.com). 2. Ensure the Cloud SQL Admin API is enabled for your project. 3. Navigate to APIs & Services > Credentials. 4. Click Create Credentials and select API key. 5. (Optional but recommended) Click Restrict key to add application or API restrictions to limit the key's usage. 6. Copy the generated API key for use in your requests. Alternatively, for higher security, use OAuth 2.0 or Service Account credentials by creating a Service Account in the IAM & Admin > Service Accounts section and downloading the JSON key file.

2. Add them to .dlt/secrets.toml

[sources.cloud_sql_admin_api_v1_source] google_cloud_api_key = "AIzaSy..." # Or if using Service Account authentication (recommended for production): google_cloud_service_account_json_path = "/path/to/your/service-account-key.json"

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 init uv add "dlt[hub]"

1. Install the dlt AI harness:

uv run dlthub 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:

uv run dlthub ai toolkit install rest-api-pipeline

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 Cloud SQL Admin API v1 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:

uv run python cloud_sql_admin_api_v1_pipeline.py

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

Pipeline cloud_sql_admin_api_v1_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset cloud_sql_admin_api_v1_data The duckdb destination used duckdb:/cloud_sql_admin_api_v1.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs

Inspect your pipeline and data:

uv run dlthub 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 instances.get and instances.list from the Cloud SQL Admin API v1 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 cloud_sql_admin_api_v1_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://sqladmin.googleapis.com", "auth": {"type": "bearer", "token": api_key}, }, "resources": [ {"name": "instances", "endpoint": {"path": "v1/projects/{project}/instances", "data_selector": "items"}}, {"name": "databases", "endpoint": {"path": "v1/projects/{project}/instances/{instance}/databases", "data_selector": "items"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="cloud_sql_admin_api_v1_pipeline", destination="duckdb", dataset_name="cloud_sql_admin_api_v1_data", ) load_info = pipeline.run(cloud_sql_admin_api_v1_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("cloud_sql_admin_api_v1_pipeline").dataset() sessions_df = data.instances.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM cloud_sql_admin_api_v1_data.instances LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("cloud_sql_admin_api_v1_pipeline").dataset() data.instances.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 Cloud SQL Admin API v1 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.
