Changes to the SuperCool API, newest first. Follow along with the [RSS feed](https://supercool.com/docs/api/changelog/feed.xml).

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 {#2026-09-30}

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](https://supercool.com/docs/llms.txt), every page as Markdown, and the [OpenAPI spec](https://supercool.com/docs/api/openapi.json).
