Cataloging Datasets

Use `search_datasets` to find the specific ONS dataset you need. You can search across 337+ datasets covering everything from population trends to trade figures, getting matching IDs and titles. This function lets you explore the full catalog without clicking through pages of results. It quickly narrows down the field so your agent knows exactly which statistical source to query next.

Defining Filters

The `get_dimensions` tool shows all available filter options for a dataset. You can see every possible dimension—like geography, time periods, or specific categories—that you need to narrow down your data set. This is essential prep work before querying. It tells your AI client exactly what query parameters are valid and how the ONS organizes its metadata.

Querying Observations

To get actual numbers, run `get_observations`. You provide a dataset ID and dimension filters you discovered earlier. The server then pulls the raw statistical data for you. Don't forget to set time=* if you want the full historical series. This tool performs the heavy lifting, transforming IDs and filter lists into usable statistics.
