search_cubes_by_title

Searches for data cubes/tables where the English or French title contains the provided search term (case-insensitive). Returns a list of matching cubes in the 'lite' format (excluding dimensions/footnotes). Multiple keywords use AND logic (e.g., "tobacco smoking age" finds cubes containing ALL three words). Results are capped at max_results (default 25). IMPORTANT: In your final response to the user, you MUST cite the source of your data. For cubes, this means including the ProductId (pid) and the Title. Raises: httpx.HTTPStatusError: If the underlying API call fails. Exception: For other network or unexpected errors during the fetch.

get_cube_metadata

Retrieves detailed metadata for a specific data table/cube using its ProductId. Includes dimension info, titles, date ranges, codes, etc. Disables SSL Verification. Corresponds to: POST /getCubeMetadata Start with summary=True (default). The summary strips noise (French translations, archive codes, footnotes) and shows only 3 sample members per dimension with _next_steps guidance. Safe for all context window sizes. Set summary=False only if you need the full raw member list or all API fields. To browse dimension codes for get_sdmx_data key construction, use get_sdmx_structure. To resolve a coordinate to a vectorId, use get_series_info. Returns: Dict[str, Any]: The metadata object for the specified cube on success. Raises: httpx.HTTPStatusError: If the API returns an error status code. ValueError: If the API response format is unexpected or status is not SUCCESS. Exception: For other network or unexpected errors. IMPORTANT: In your final response to the user, you MUST cite the source of your data. For cubes, this means including the ProductId (pid) and the Title.

get_changed_series_data_from_cube_pid_coord

Retrieves changed series data (data points that have changed) using Cube ProductId and Coordinate string. Coordinates are automatically padded to 10 dimensions. Disables SSL Verification. Corresponds to: POST /getChangedSeriesDataFromCubePidCoord Returns: Dict[str, Any]: A dictionary containing the changed series data object. Raises: httpx.HTTPStatusError: If the API returns an error status code. ValueError: If the API response format is unexpected or status is not SUCCESS. Exception: For other network or unexpected errors. IMPORTANT: In your final response to the user, you MUST cite the source of your data. For changed series data, this means including the VectorId, ProductId (pid), and Coordinate.

get_series_info

Resolve one or more {productId, coordinate} pairs to series metadata (vectorId, titles, frequency, UOM, etc.) in a single API call. Use this to find vectorIds before fetching data with get_sdmx_data or get_sdmx_vector_data. Pass one item or many — same tool either way. Coordinates are automatically padded to 10 dimensions. Corresponds to: POST /getSeriesInfoFromCubePidCoord (accepts array) NOTE: Response fields like scalarFactorCode, frequencyCode, and memberUomCode use StatCan numeric codes. Call get_code_sets() to decode them (e.g. frequencyCode 6 = "Monthly", scalarFactorCode 0 = "Units"). Returns: List of series metadata dicts, paginated with _guidance if >50 results. Raises: httpx.HTTPStatusError: If the API returns an error status code. ValueError: If no items return SUCCESS. Exception: For other network or unexpected errors. IMPORTANT: In your final response cite the ProductId and Coordinate for each series.

get_changed_cube_list

Get the list of data tables/cubes that were updated on a specific date (YYYY-MM-DD). Disables SSL Verification. Corresponds to: GET /getChangedCubeList/{date} Returns: List[Dict[str, Any]]: A list of dictionaries describing changed cube objects. IMPORTANT: In your final response to the user, you MUST cite the source of your data. For changed cubes, this means including the ProductId (pid) and Title.

get_series_info_from_vector

Request series metadata (productId, coordinate, titles, frequency, etc.) by Vector ID. Disables SSL Verification. Corresponds to: POST /getSeriesInfoFromVector Returns: Dict[str, Any]: A dictionary containing the series metadata object. Raises: httpx.HTTPStatusError: If the API returns an error status code. ValueError: If the API response format is unexpected or status is not SUCCESS. Exception: For other network or unexpected errors. IMPORTANT: In your final response to the user, you MUST cite the source of your data. For series info, this means including the VectorId, ProductId (pid), and Coordinate.

get_bulk_vector_data_by_range

Fetches bulk data for multiple vectors filtered by *release date* range (YYYY-MM-DDTHH:MM), NOT by reference period. Use this when you want data released within a specific date/time window (e.g., "all updates released yesterday"). *** IMPORTANT: release date vs reference period *** - Use THIS tool when you want: "data released between date A and date B" - Use get_sdmx_vector_data (startPeriod/endPeriod) when you want: "data for the time period YYYY to YYYY" get_sdmx_vector_data is more reliable and filters by reference period, not release date. *** LARGE RESPONSE WARNING *** This tool can return hundreds of flattened data points. If the response exceeds context limits, narrow the request: use fewer vectorIds, or use offset/limit pagination to page through results in smaller chunks. Response is pre-flattened: each element is one data point with vectorId, productId, coordinate, and all value fields injected at the top level. Disables SSL Verification. Corresponds to: POST /getBulkVectorDataByRange Returns: List[Dict[str, Any]]: Flat list of data point dicts, each tagged with vectorId, productId, and coordinate. Raises: httpx.HTTPStatusError: If the API returns an error status code. ValueError: If the API response format is unexpected or no vectors return SUCCESS. Exception: For other network or unexpected errors. IMPORTANT: In your final response to the user, you MUST cite the source of your data. For vector data, this means including the VectorId and Release Time.

get_changed_series_data_from_vector

Get changed series data (data points that have changed) for a series identified by Vector ID. Disables SSL Verification. Corresponds to: POST /getChangedSeriesDataFromVector Returns: Dict[str, Any]: A dictionary containing the changed series data object. Raises: httpx.HTTPStatusError: If the API returns an error status code. ValueError: If the API response format is unexpected or status is not SUCCESS. Exception: For other network or unexpected errors. IMPORTANT: In your final response to the user, you MUST cite the source of your data. For changed series data, this means including the VectorId.

get_changed_series_list

Get the list of series (vectorId, productId, coordinate, releaseTime) that were updated on a specific date (YYYY-MM-DD). Disables SSL Verification. Corresponds to: GET /getChangedSeriesList/{date} Returns: List[Dict[str, Any]]: A list of dictionaries describing changed series objects. Raises: httpx.HTTPStatusError: If the API returns an error status code. ValueError: If date format is invalid or API response format is unexpected. Exception: For other network or unexpected errors. IMPORTANT: In your final response to the user, you MUST cite the source of your data. For changed series, this means including the VectorId.
