Input Schema

Name	Required	Description
`datasetId`	No	Dataset identifier required for the following operations: - For type=dataset-metadata: Get dataset details - For type=column-info: Get column information - For type=data-access: Specify which dataset to query (e.g., 6zsd-86xi)
`domain`	No	Optional domain (hostname only, without protocol). Used with all operation types.
`group`	No	For type=data-access only. Groups results for aggregate functions.
`having`	No	For type=data-access only. Filters for grouped results, similar to where but for grouped data.
`limit`	No	Maximum number of results to return: - For type=catalog: Limits dataset results - For type=data-access: Limits data records returned
`offset`	No	Number of results to skip for pagination: - For type=catalog: Skips dataset results - For type=data-access: Skips data records for pagination
`order`	No	For type=data-access only. Orders the results based on specified columns (e.g., "date DESC").
`q`	No	For type=data-access only. Full text search parameter for free-text searching across the dataset.
`query`	No	Search or query string with different uses depending on operation type: - For type=catalog: Search query to filter datasets - For type=data-access: SoQL query string for complex data filtering
`select`	No	For type=data-access only. Specifies which columns to return in the result set.
`soqlQuery`	No	For type=data-access only. Optional SoQL query string for filtering data. This is an alias for the query parameter and takes precedence if both are provided.
`type`	Yes	The type of operation to perform: - catalog: List datasets with optional search - categories: List all dataset categories - tags: List all dataset tags - dataset-metadata: Get detailed metadata for a specific dataset - column-info: Get column details for a specific dataset - data-access: Access records from a dataset (with query support) - site-metrics: Get portal-wide statistics
`where`	No	For type=data-access only. Filters the rows to be returned (e.g., "magnitude > 3.0").
