Bluesky is open — but the AT Protocol is low-level
Posting on Bluesky means speaking the AT Protocol directly: authenticate a session against the user's PDS, resolve their DID, and createRecord with byte-indexed rich-text facets for every link, mention and hashtag. Images are blobs you upload then reference. Outstand turns all of it into a single request.

Bluesky API FAQ
The questions developers ask before they build.
Does Bluesky have an official API?
Yes — Bluesky is built on the open AT Protocol, which lets apps create posts, threads and media records and read engagement. Outstand is a managed layer on top of it, so you skip the session, DID and facet handling.
Do I need an app password to post to Bluesky?
You connect with OAuth or a Bluesky app password. Outstand stores the credential securely and manages the AT Protocol session for you — there is no app-review process on Bluesky.
Can I post images and video to Bluesky via API?
Yes. Add up to 4 images (or a video) in the media array and Outstand uploads each as a blob and embeds it in the post record.
Do links, mentions and hashtags become clickable?
Yes. The AT Protocol requires byte-indexed rich-text facets for these to be clickable. Outstand computes the facets automatically, so URLs, @handles and #hashtags in your content just work.
Can I post a thread on Bluesky via API?
Yes. Send a containers[] array — the first container is the root post and each following container is published as a reply with the correct root and parent refs.
Can I schedule Bluesky posts via the API?
Yes. Add a scheduledAt ISO-8601 timestamp (up to 30 days ahead) and Outstand publishes it automatically — no cron or queue on your side.
Can I delete a Bluesky post via the API?
Yes. Bluesky supports deleting records via the API, and Outstand exposes it through DELETE /v1/posts/{id}/remote.
