Scrapes a creator's Amazon Shop page by URL, returning their storefront profile and product collections. The initial request also returns videos already embedded on the storefront page without requiring a pageToken. Videos include an id, title, thumbnail, and attached ASINs. Pass each returned pageToken back unchanged with the same shop URL. A paginated page can contain lists, videos, or both. Tokens are opaque: known values can begin with amzn1.ideas, amzn1.vse.video, or amzn1.shoppablemedia, but clients should not infer the response type from the prefix. Uses the caller's OpenAny gateway credentials. Charges and authorization are determined by the gateway.
