Sydium

Account analytics time-series (optional from/to YYYY-MM-DD)

get_analytics

Store an image or video in Sydium and return the media URL that publish_post and update_post require. Media MUST be hosted by Sydium - an external URL passed straight to publish_post is rejected - so call this first. Pass EITHER `file` (a file the user attached to this conversation) OR `url` (a direct, publicly reachable link to the image or video itself, not a web page containing it). Supported: jpeg, png, gif, webp, mp4, mov, webm - up to 50MB. HEIC/AVIF photos (the iPhone default) are NOT supported; ask the user to convert to JPEG. Returns the media url plus its measured size, dimensions and duration, and `acceptedBy` / `rejectedBy`: which platforms will take this file. Pass `postType` when you already know it (reel, story, carousel...) - story and carousel limits are stricter than the platform default, and without it `acceptedBy` is optimistic. Check `rejectedBy` before scheduling. The media is REMOVED once its post publishes, so a url cannot be reused for a second post - call add_media again. If the user attached a file to this conversation but you cannot pass it to `file`, that is a limitation of the CLIENT you are running in, not of Sydium - say so plainly, in those terms, and ask for a public link, which works everywhere. Do not tell the user that Sydium cannot accept their image, and do not claim an upload happened.

add_media

Cancel a scheduled post operation by id (only targets still scheduled are cancelled)

cancel_post

Edit a scheduled post operation by id: change its caption, media, and/or scheduled time. Only targets still scheduled are updated; omitted fields are left unchanged; media:[] clears media. `media` entries must be Sydium-hosted URLs returned by add_media; any other URL is rejected. Cannot change which platforms it posts to - cancel and re-create for that.

update_post

Generate a social caption with AI

generate_caption

Get a publish operation's per-target status

get_post_status

List the agency clients under this team (id/name/status). Pass a client id to other tools' clientId to act for that client.

list_clients

List connected social accounts for the team, or for a specific agency client via clientId. Also returns `team`, the workspace this connection is bound to - a connection reaches exactly one workspace, fixed when the user authorized it. If the user expected different accounts, they likely authorized a different workspace: say which one you are on and tell them to reconnect and pick the right one.

list_accounts

List the team's upcoming scheduled posts (optional from/to ISO dates to bound a window, e.g. this week)

list_scheduled_posts

Get posting limits/capabilities; optional single platform

get_platform_capabilities
