Mindshare
/mindshare
Returns the share of eligible social attention for exactly one resolved asset or non-asset subject. Values are decimal fractions from 0 to 1. Restricting results to selected author clusters requires Pro. Asset selectors support equities, commodities, indices, and crypto assets returned by GET /assets; commodity and index IDs use asset_class=equity. Parameter rules: One of asset_id or subject_id is required. asset_id requires asset_class. subject_id and asset_class cannot be combined. subject_id and asset_id cannot be combined.
Parameters
Canonical identifier returned by /assets. Stock, commodity, and index IDs are normally ticker or market symbols and use asset_class=equity; crypto IDs are canonical crypto slugs. asset_class is mandatory whenever asset_id is present.
Example:NVDA
Namespace of asset_id, or the market class for endpoints with a class-scoped global view. Stocks, commodities, and indices use equity. Equity is the documented default only where the endpoint description states a default.

Canonical non-asset identifier returned by /subjects. It cannot be combined with asset_id or asset_class.
