Poly Haven's API keys assets by slug, exposes date_published, img_version and files_hash (a SHA1 of the files listing that changes when files update) and dimensions in millimetres, but no per-asset licence field: the README states assets are CC0 while the live API requires a 'Powered by Poly Haven' credit, and the API software itself is AGPL.
