Interface WebSearchQueryOutput

Synthesized answer, only when includeAnswer was requested and the provider produced one.

Every provider tried, in order — including on success.

If the primary rate-limits every call and the secondary quietly serves everything, nothing else makes that visible while the bill moves to a vendor nobody chose.

Normalised results. Legitimately empty for a narrow query — that is not a failure.

Name of the provider that actually served this result.
