Square Post

Posts text updates to Binance Square using API authentication. You tell Claude what to share, it can optionally polish the content for readability, then publishes via the official Binance API. Returns a direct URL to your post on success. The skill handles all the header formatting and error codes (sensitive content detection, rate limits, missing auth, etc). Supports text only for now, no images or other media. If you're active on Binance's social platform and want to automate posting market thoughts or updates without leaving your conversation with Claude, this handles the API ceremony. Daily post limits apply through the OpenAPI, so check your quota if you hit errors.

Square Post Skill

Purpose

Publish new content to Binance Square by running the local scripts in scripts/.

Supported post types:

Text-only short posts
Image posts with up to 4 images
Long articles with a title and optional cover image
Video posts with an auto-generated cover image

Do not hand-code API requests for normal posting. The scripts own upload, polling, cover generation, and publish behavior.

Runtime Dependencies

Node.js 18 or newer. The scripts use native ES modules and the built-in fetch API.
ffmpeg is required for video posts because post-video.mjs extracts the first frame as the cover image.
ffprobe is required when a video duration is not provided by the user.
Network access is required for Binance Square OpenAPI requests and presigned media uploads.
