Agent-native social publishing

Tell your agent. Post everywhere.

Your agent prepares the request. Postminion validates ownership, permissions, platform rules, and timing. Your connected social networks publish it asynchronously.

One instruction, three clear roles

Your agent

Understands the task

Discovers your accounts, composes structured inputs, asks for approval when needed, and follows up on status.

Postminion

Enforces your rules

OAuth scopes, ownership, subscription, media safety, revisions, platform settings, scheduling, retries, and revocation.

Social networks

Publish downstream

Instagram, TikTok, YouTube, Threads, Facebook, and LinkedIn return their own eventual results.

What agents can do

  • ✓ Discover connected accounts
  • ✓ Validate without creating
  • ✓ Create drafts
  • ✓ Schedule by timezone
  • ✓ List and inspect posts
  • ✓ Revision-safe updates
  • ✓ Cancel scheduled work
  • ✓ Publish now, if you allow it

Permissioned, visible, revocable

No Postminion API key is pasted into the client. The consent screen lists read, draft, scheduling, update, media, cancellation, and immediate-publish access separately. Access covers every social account in the workspace you approve, including ones you connect later.

The Agents page shows safe activity and lets you revoke one client immediately without signing you out or disconnecting social accounts.

Media and results behave honestly

Controlled imports

Remote media must use public HTTPS. Postminion blocks private destinations, caps downloads, sniffs the real type, normalizes files, and stores verified media under your ownership.

Validation stays read-only

validate_post checks URL shape and intent without downloading. Definitive media checks happen only in an authorized mutation.

Accepted is not published

Scheduling and immediate publish calls return an accepted Postminion state. Use get_post for per-account downstream outcomes.

Try asking

“List my connected social accounts and tell me what each supports.”
“Create a draft for my Facebook Page and LinkedIn profile. Do not schedule it.”
“List my posts scheduled for the next seven days.”
“Schedule this post for 9:30 AM tomorrow in Asia/Makassar after validating it.”
“Move that draft to Friday at 2:00 PM in America/New_York, using its current revision.”
“Accept this post for immediate publishing, then check its status until the platform result is available.”
