Create Instagram reel
Input
caption optionalReel caption; empty for none. Max 2200 chars.
Default: ""video_url optionalDirect URL of the mp4 to post as a reel, fetched by the browser itself (so it works on devices with no outbound network of their own). Capped at 25MB. THIS IS ALSO HOW TO POST A LOCAL FILE on an extension-paired device: serve it over localhost and pass that URL — `python3 -m http.server 8765 --bind 127.0.0.1` in the file's directory, then video_url=http://127.0.0.1:8765/clip.mp4. Verified: a 2.8MB local mp4 published that way on a device where video_path is refused.
video_path optionalPath to a local mp4, attached straight from disk via CDP — nothing encoded, no size ceiling. Resolved on the machine RUNNING THE BROWSER, and only works on a device whose browser PERMITS DOM.setFileInputFiles. An extension-paired browser does NOT: it refuses with "Not allowed", and no route attaches a local file directly there (builtins.uploadFile with a format:file input is the same CDP call underneath). Prefer the localhost recipe on video_url, which needs no special device. Absolute paths only. Takes precedence over video_url.
Output
url requiredshared requiredpk optionalcode optionalcaption optionalvideo_bytes optionalSize in bytes of the video injected into the composer. null for video_path, where the browser opens the file itself and the bytes never cross the driver boundary.
instagram.comDelete Instagram post
Delete one of your own Instagram posts or reels by shortcode. Opens the post, drives More options then Delete and the confirmation, and then reloads the post's link to prove it is really gone before reporting success. Returns the shortcode, the media id when Instagram exposes it, and whether the post was verified as removed. Fails clearly when the shortcode is not available to you (already deleted, private, or another account's) and when the post is still live after the confirmation.
instagram.comGet Instagram post comments
Fetch the preview comments of an Instagram post or reel by shortcode, plus its caption and counts. Returns code, url, caption, comments (text, user, verified, created_at, like_count, reply_count), like_count, view_count, comment_count, and comments_disabled. Only returns the comments Instagram renders by default, not the full thread, capped to count.
instagram.comSend Instagram DM
Send a DM to an Instagram user by their username: plain text, an image attachment, or both together. Takes the image as base64 so it runs from any client. Returns ids/timestamps for whichever parts were sent, and the recipient-side restriction banner if one is shown right after sending.
