`ask_rightshold`Call when you have a rights or licensing question in plain English, such as 'Can I use CC BY-NC 4.0 images in a paid ad campaign?'. Returns the license or registered resource and the use it understood, and a deterministic answer with reasons; it asks for clarification instead of guessing. Check the understood use before relying on it. Free, no key.	Call when you have a rights or licensing question in plain English, such as 'Can I use CC BY-NC 4.0 images in a paid ad campaign?'.

`assess_resource_for_use`Call when the asset is a registered resource and you need its exact answer for one use. Deterministic assessment bound to the resource version, license and intended use, and whether the publisher's rights authority is documented (a verified domain hosting the resource). Four dispositions with reason codes; no trust score. Free, no key.	Call when the asset is a registered resource and you need its exact answer for one use.

`check_license`Call before using any image, text, dataset, code, font or model you did not create.

Returns permitted, prohibited, needs_review or not_documented, with duties and an uncertainty block (what the verdict leaves open; whether a human must review). Free, no key.

`check_listing`Pre-install check against the Rightshold Store and its signed revocation list: give a package hash (SHA-256), an endpoint or package URL, or a store slug. Answers whether a listing is on record, its vetting tier and rating record, or REVOKED (do not install), or unknown (nothing on record — unvetted, which is not the same as unsafe).
