Search stock media (Pexels / Pixabay / Freesound / Klipy)

Search licensed stock media by keyword. Pass query for one search, or queries[] (≤10) to run a batch in ONE call — the batch returns results[], one entry per query in order, each with its own candidates (and an error string if that single query failed; one bad query never discards the rest). kind selects the corpus (video/photo default to Pexels; Pixabay is explicitly selectable; sfx → Freesound CC0-only; gif → Klipy); defaults to video. Returns ranked candidates each carrying an opaque candidateId — pass it to import_resource to bring the asset into a project. Free + rate-limited; results are cached for 7 days, after which a candidateId must be refreshed by searching again. For sfx, bound the result by clip length with durationSec — impacts/ticks ≈ 0–2s, risers/whooshes ≈ 2–8s, ambients unbounded. For video, use minWidth/minHeight to exclude smaller renditions.
