Open Government, Singapore Python API Docs | dltHub
Build a Open Government, Singapore-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.
Last updated:
Data.gov.sg provides a portal to access official Singapore government datasets and real-time APIs for development. The REST API base URL is https://api-production.data.gov.sg/v2/public/api and API keys are recommended for production workflows and are passed as a 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 Open Government, Singapore data in under 10 minutes.
What data can I load from Open Government, Singapore?
Here are some of the endpoints you can load from Open Government, Singapore:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| datasets | /v2/public/api/datasets | GET | data.datasets | List all available datasets (page-based) |
| dataset_search | /api/action/datastore_search | GET | result.records | Search rows in a dataset (offset-based) |
| pm25_realtime | /v2/real-time/api/pm25 | GET | Get PM 2.5 real-time data | |
| initiate_download | /v1/public/api/datasets/{datasetId}/initiate-download | GET | Initiate download for a full dataset | |
| poll_download | /v1/public/api/datasets/{datasetId}/poll-download | GET | Poll status of a dataset download |
How do I authenticate with the Open Government, Singapore API?
Requests must include an 'x-api-key' header containing your API key.
1. Get your credentials
- Navigate to https://data.gov.sg/ and click on the login icon in the top right corner. 2. If you do not have an account, click 'Sign Up' and register using your email address. 3. Verify your identity via the OTP sent to your email. 4. Once logged in, navigate to your user profile or dashboard. 5. Locate and click on the 'API Keys' or 'Create API Key' section. 6. Follow the prompts to request either a developer or production API key, providing details on your use case, and click 'Create' to generate your key. Store this key immediately as it cannot be viewed again.
2. Add them to .dlt/secrets.toml
[sources.open_government_singapore_source] data_gov_sg_api_key = "your_api_key_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 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 Open Government, Singapore 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 open_government_singapore_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline open_government_singapore_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset open_government_singapore_data The duckdb destination used duckdb:/open_government_singapore.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 datasets and collections from the Open Government, Singapore 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 open_government_singapore_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api-production.data.gov.sg/v2/public/api", "auth": {"type": "api_key", "api_key": api_key, "name": "x-api-key", "location": "header"}, }, "resources": [ {"name": "datasets", "endpoint": {"path": "v2/public/api/datasets", "data_selector": "data.datasets"}}, {"name": "dataset_search", "endpoint": {"path": "api/action/datastore_search", "data_selector": "result.records"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="open_government_singapore_pipeline", destination="duckdb", dataset_name="open_government_singapore_data", ) load_info = pipeline.run(open_government_singapore_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("open_government_singapore_pipeline").dataset() sessions_df = data.dataset_search.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM open_government_singapore_data.dataset_search LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("open_government_singapore_pipeline").dataset() data.dataset_search.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 Open Government, Singapore 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.
