# Changelog

What changed on the API and these pages, newest first.

## Entries

- 2026-09-04: The key layer, in private beta: sign in with Roblox at /account, keys with scopes, the [account endpoints](account-api), per-product [rate limits and quotas](rate-limits), [idempotency keys](idempotency) on writing endpoints, and `x-request-id` on every answer. The error shape gains `code`, `requestId`, `param` and `docUrl` beside the `error` text it always carried. The [terms](terms), [privacy policy](privacy), [retention schedule](retention) and [sub-processors](subprocessors) are pages here.
- 2026-09-04: `/v1/limits` and `/v1/limits/{id}`: every Roblox platform limit the studio's games run against, as JSON, with the date each value was read.
- 2026-09-03: These pages. The docs moved from one long page to a site of their own, with a quickstart, a reference per endpoint, the fields, and the caching and error contracts written down.
- 2026-08-23: v1 opens on api.dietbloxycola.com and api.bloxycola.com: the index, live numbers, the games list and one game by universe id.
