Comments API
Read, reply, hide, and moderate comments across Instagram, Facebook, YouTube, and more — one endpoint, every platform.
Fetch comments from any post across all connected platforms. Filter by date, sentiment, or keyword. Paginate through thousands with a consistent cursor API.
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 toxic or off-brand comments without deleting them. Unhide later if needed. Supported on Instagram, Facebook, and YouTube.
Delete comments made by your connected accounts. Platform rules apply — you can only delete comments you own or comments on your own content.
// Fetch comments from a post
const comments = await aether.inbox.list({
postId: "post_abc123",
platform: "instagram",
limit: 50,
});// Reply to a comment
await aether.inbox.reply("msg_xyz789", {
text: "Thanks for the kind words! 🙏",
});// Hide a comment
await aether.inbox.hide("msg_xyz789");
// Unhide later
await aether.inbox.unhide("msg_xyz789");| Platform | Read | Reply | Hide | Delete |
