• autoposter_upload_media

  Uploads an image or video to Auto Poster media library. Accepts files generated in ChatGPT (e.g. DALL-E images in /mnt/data/), uploaded files, or public image URLs. Direct chat download limit is 100MB. For larger videos or files (>100MB), tell the user to provide a direct public file URL or use autoposter_get_media_upload_url for direct S3 upload up to 5GB. If the image exists only in the chat or on the user's device and cannot be sent here, use autoposter_create_upload_link instead.

  Parameters:

  • url — string — Optional public image or video URL or data URI to upload into media library.
  • file — File object provided by ChatGPT for AI-generated images or uploaded files.
  • name — string — Optional display name or title for the media file.

  Hints: read-only no · destructive no · idempotent not declared · open-world yes

• autoposter_get_media_upload_url

  Only for clients that can perform an HTTP PUT or multipart POST (not chat-only clients such as Gemini): if you cannot make that request yourself, use autoposter_create_upload_link instead. Generates a presigned S3 upload URL for direct, high-speed upload of videos or images up to 5GB without size limits or timeouts. Returns direct PUT url, POST upload fields, and public CDN URL.

  Parameters:

  • fileName (required) — string — Name of the file including extension (e.g. 'promo_video.mp4', 'photo.jpg').
  • contentType (required) — string — MIME type of the media (e.g. 'video/mp4', 'image/jpeg', 'image/png').

  Hints: read-only no · destructive no · idempotent not declared · open-world yes

• autoposter_create_upload_link

  Creates a short-lived link where the user can upload images from their device into the Auto Poster media library. Use this when the user wants to attach an image that exists only in the chat or on their device (no public URL) and your client cannot send file contents. Give the link to the user, wait until they say the upload is done, then call autoposter_list_media (newest first) and attach the image with mediaIds in autoposter_draft_post or autoposter_schedule_post.

  Hints: read-only no · destructive no · idempotent not declared · open-world no

• autoposter_draft_post

  Creates a draft post for human review. If API key lacks direct publish, post is saved as pending_approval and notifications are sent to workspace approvers. Accepts mediaUrls (public URLs) or files (AI-generated images or uploaded files from chat up to 100MB). For large video files over 100MB, tell the user to provide a direct public file URL or use autoposter_get_media_upload_url.

  • accountIds (required) — array — List of account IDs from autoposter_list_accounts.
  • content (required) — string — Base text content of the post.
  • files — array — Optional files generated in chat or uploaded by user to attach to the post.
