Changelog

Changes to the SuperCool API, newest first. Follow along with the RSS feed.

Within /v1, changes are additive: new endpoints, new fields, new event types, new reason values. Build your integration to ignore fields and values it doesn't know. Anything that would break an existing integration gets a new version.

#2026-09-30 — The SuperCool API is live

Your SuperCool agent is now available over HTTPS at https://api.supercool.com/v1.

• Messages: POST /v1/messages sends your agent a message, with inline files or large uploads. Follow it with GET /v1/messages/{id}?wait=, its events, or webhooks. Each message reports its jobs, files and credits used.
• Webhooks: signed with Standard Webhooks, with retries for up to 3 days and per-message routing.
• Uploads: files up to 500 MB through presigned uploads.
• Work and files: read any chat, including ones started in the app, and get fresh download links.
• Keys and dashboard: nicknamed sc_key_ API keys with optional expiry, usage per key, and a request inspector with every request from the last 30 days.
• Docs: these pages, llms.txt, every page as Markdown, and the OpenAPI spec.
