Comments API

Manage Comments Across Every Platform

Read, reply, hide, and moderate comments across Instagram, Facebook, YouTube, and more — one endpoint, every platform.

Read comments at scale

Fetch comments from any post across all connected platforms. Filter by date, sentiment, or keyword. Paginate through thousands with a consistent cursor API.

Reply programmatically

Post a reply to any comment with a single API call. Works for Instagram, Facebook, YouTube, LinkedIn, Threads, and Reddit — same endpoint, different platform.

Hide & unhide

Hide toxic or off-brand comments without deleting them. Unhide later if needed. Supported on Instagram, Facebook, and YouTube.

Delete your own comments

Delete comments made by your connected accounts. Platform rules apply — you can only delete comments you own or comments on your own content.

Three actions, one API surface

Read comments
// Fetch comments from a post
const comments = await aether.inbox.list({
  postId: "post_abc123",
  platform: "instagram",
  limit: 50,
});
Reply to a comment
// Reply to a comment
await aether.inbox.reply("msg_xyz789", {
  text: "Thanks for the kind words! 🙏",
});
Hide & unhide
// Hide a comment
await aether.inbox.hide("msg_xyz789");

// Unhide later
await aether.inbox.unhide("msg_xyz789");

Frequently asked questions

What platforms support the Comments API?+

Instagram, Facebook, YouTube, LinkedIn, Threads, and Reddit. The specific actions available (read, reply, hide, delete) vary by platform — the table above shows exactly what each supports.

Can I auto-reply to comments?+

Yes. Use the Comments API with webhooks — subscribe to the comment.created event, receive the comment payload in real time, and call POST /v1/inbox/{id}/reply from your webhook handler. The Aether MCP server also supports this workflow via AI agents.

Can I moderate comments at scale?+

Yes. Use the list comments endpoint to fetch in bulk, filter by sentiment or keyword in your code, and call hide or delete in a loop. The API is designed for high-volume moderation workflows.

Do webhooks fire when new comments arrive?+

Yes. Subscribe to the comment.created event and Aether will POST to your endpoint in real time when new comments appear on any connected account's posts. Payloads are HMAC-SHA256 signed.

Can I like comments?+

Like reactions on comments are supported for Instagram and Facebook. Use POST /v1/inbox/{id}/like. YouTube comment likes are not available via the YouTube Data API for third-party apps.

What does the Comments API cost?+

The Comments API is included in all Aether plans including the free tier. No add-on, no per-call fee beyond your plan's API call limits.
