Response shape

Always returns: datasets, returned, has_more

Field	Type	Description
`datasets`	array
`returned`	number	Datasets returned in this page. The upstream provides NO corpus total — it is cursor-paginated — so no total is reported rather than a fabricated one.
`has_more`	boolean	True when the upstream returned a continuation cursor.
