Common questions
What is the largest file I can upload?
100 MB per file over REST, 10 MB over MCP.
Should I use multipart or JSON?
Multipart. Base64 JSON is 33% bigger and is meant for agents that can't attach files.
How long do uploads last?
7 days. Posting an older upload returns 409 media_expired; upload it again.
How do I make a carousel?
Upload each file, then pass all the ids in mediaIds in order.
