check_feature_supportread-onlyCan I use this feature, and from which browser version? Accepts a loose name (":has()", "container queries", "css-grid") and resolves it to a caniuse feature, then returns the earliest continuously-supported version per major browser, global usage percentage, and a conservative safe_to_use flag. Use this first; it answers the whole question in one call.
get_feature_by_idread-onlySupport table for an exact caniuse feature id. Use when the id is already known, for example from a previous search. No fuzzy matching is applied.
search_featuresread-onlyFind the caniuse feature id for a loose query. Use when a query is ambiguous and you want to choose between candidates before checking support.
