Get media from a creator's chat

Returns a cursor-paginated list of media items shared between the specified creator and user. Media is extracted from chat messages and ordered by date (newest first).

Pagination Flow:

• First request: Omit the cursor parameter, returns first 20 media items (or specified limit)
• Subsequent requests: Use the nextCursor from the previous response
• End of results: nextCursor will be null

{
  "data": [...media items...],
  "nextCursor": "..." // Pass this to the next request to get the following page
}
