What you unlock
Post tweets
Compose and publish tweets directly from Mantle — text, threads, or media posts.
Upload media
Upload images and videos to attach to tweets before publishing.
Account lookup
Retrieve your own account details including username, bio, and follower count.
Connect X (Twitter)
Authorize with X
Click Connect and sign in with your X account. Grant the requested permissions so Mantle can post and upload
media on your behalf.
This integration uses the X API free tier, which supports posting tweets, uploading media, and looking up your own
account. Read endpoints (searching tweets, reading timelines, looking up other users) require a paid API plan and are
not included.
