154154* **Rate limit groups:** Each entry in the response represents one rate limit group. Model rate limits are grouped so that several model versions share a single set of limits, and other groups cover resources such as the Message Batches API, the Files API, the Token Counting API, agent skills, and the web search tool.
155155* **`group` object:** Present on every entry, it identifies the rate limit group the entry applies to. It always has `type`, which is one of the `group_type` values, and `id`, an opaque identifier with the `rlg_` prefix. On `model_group` entries it also has `display_name`, Anthropic's current label for the group, such as `Claude Sonnet 4.x`. The label is for display only and may change. Other group types have no `display_name`.
156* **The `id` inside `group`:** A group has the same `id` in every organization and on every workspace override, and it never changes. Use it to match entries across organizations or against your own catalog. The entry's own `id` differs per organization, and `models` changes when Anthropic moves a model between groups. Neither is a stable key for the group.

157157* **`group_type`:** The query parameter that restricts the list to one group type. See [Filtering by group type](https://platform.claude.com/docs/en/manage-claude/rate-limits-api#filtering-by-group-type) for the values.
158158* **`models` list:** For `model_group` entries, the `models` field lists every model ID and alias that counts against that group's limits. Use this list to look up which group any model string falls under. For other group types, `models` is `null`.
159159* **`limits` list:** Each group carries a list of `{type, value}` pairs. The `type` field identifies the limiter (such as `requests_per_minute`, `input_tokens_per_minute`, or `output_tokens_per_minute`) and `value` is the configured limit. See [Rate limits](https://platform.claude.com/docs/en/api/rate-limits) for how each limiter is measured and enforced.

496 To retrieve your organization's workspace IDs, use the [List Workspaces](https://platform.claude.com/docs/en/api/organization/workspaces/list) endpoint, or find them in the [Claude Console](https://platform.claude.com/settings/workspaces). List Workspaces includes the default workspace only when you pass `include_default=true`.
