Post from Claude, a script, or your own app
The dashboard composer and the HTTP API hit the same publish path.
After you sign in, open API Keys, create a key, and send Authorization: Bearer to https://postbroadcaster.com/api/external/posts.
List accounts, publish immediately, or pass scheduledFor. Per-platform overrides use the same keys as the UI (FACEBOOK, INSTAGRAM, TWITTER, BLUESKY, and so on).
Full reference lives in the dashboard after login: sign in, then API Keys → docs. There is no separate billed “MCP add-on” page because the API is part of the product.
Try the composer
Sign in with Google, connect the accounts you actually use, and publish or schedule.
