Threads API
Aether tracks every Threads API update from Meta and absorbs breaking changes before they reach your code. Cross-post to Instagram and Threads simultaneously in one API call.
import Aether from "aether";
const aether = new Aether({ apiKey: process.env.AETHER_API_KEY });
const post = await aether.posts.create({
text: "One API call. Seven platforms. No OAuth nightmares.",
profileIds: ["th_user123", "ig_abc123"], // Threads + Instagram together
platforms: {
threads: { replyControl: "everyone" },
instagram: { contentType: "post" },
},
scheduledFor: "2026-06-01T12:00:00Z",
});
// → { id: "post_th1", status: "scheduled", platforms: ["threads", "instagram"] }Note: Threads API is provided by Meta and is in active development. Aether tracks all changes and absorbs breaking updates before they reach your integration.

One API call. Aether handles OAuth, rate limits, media hosting, and platform-specific formatting.
Threads API launched in June 2024 and has been broadly stable since. Aether tracks every Meta update and absorbs breaking changes, so your integration remains unaffected even during Threads API revisions.
Text posts (up to 500 characters), single images, single videos, link attachments, and carousels (up to 10 media items). Reply threads and quote posts are also supported via the Inbox API.
Yes. If you have both platforms connected, pass both profileIds in one API call. Aether formats the content for each platform's requirements automatically — including character limits and media format differences.
Threads applies 250 API calls per 24 hours per token. Aether surfaces the remaining limit in API response headers and queues posts gracefully if you approach it.
Yes. The Inbox API supports reading replies and posting reply threads. Reply control (everyone, accounts you follow, or mentioned only) is configurable per post via the platform override.
Threads is broadly available globally. A small number of countries still have platform restrictions. Aether returns a specific error code when posting is blocked for a connected account's region.
