Create a root key with the permissions listed on this page under Root Keys in the dashboard sidebar. CLI commands can instead use a session from unkey login with the required permissions. See Permission reference for every permission.
Check several s at once. data.passed is true only when every check passes. Each check’s result is in data.limits. If one check fails, none of the limits are charged. A deleted namespace anywhere in the list fails the whole request with 410 Gone and err:unkey:data:ratelimit_namespace_gone. Calls POST /v2/ratelimit.multiLimit. See Limit and multi-limit.

Usage

--body takes a JSON array, not an object.

Flags

string
required
JSON array of 1 to 100 checks, each with namespace, identifier, limit, duration, and optional cost, the same fields ratelimit limit takes as flags.

Shared flags

Every resource command takes these. See CLI output and shared flags.
string
Root key used for the request. Falls back to UNKEY_ROOT_KEY, then stored credentials, including a CLI session. See CLI authentication for the full precedence order.
string
default:"https://api.unkey.com"
Base URL of the API. Falls back to UNKEY_API_BASE_URL. You don’t normally need to set it.
string
default:"~/.unkey/config.toml"
Path of the TOML config file. Falls back to UNKEY_CONFIG. An explicit --config takes precedence over a stored CLI session. Browser login stores a session, not a root key in this file. See CLI authentication.
enum
default:"human"
Use human (default) for name-first summary tables and single-response trees, or json for the unchanged full response envelope, including all fields and pagination. Trees wrap long values without truncation. Terminal tables use relative timestamps and may shorten display names and descriptions, but never identifiers, slugs, or credentials. Redirected human output keeps complete values and uses RFC3339 UTC timestamps. Falls back to UNKEY_OUTPUT; other values are rejected. --json also selects JSON output. Add --debug to print the request ID to stderr. See Output formats.
boolean
Print the successful response’s request ID to stderr, separate from stdout.
boolean
Print the full response as JSON. Takes precedence over a valid --output or UNKEY_OUTPUT value.
string
Send this JSON as the whole request body instead of using the command’s flags. You can’t combine it with them.

Required permissions

Your root key needs unkey:v1:<workspace_id>:projects/<project_id>/ratelimits/namespaces/<namespace_id>#limit for every namespace in the request. Use * for the namespace ID to cover all namespaces in a project. To create missing namespaces on first use, the key also needs unkey:v1:<workspace_id>:projects/<project_id>/ratelimits/namespaces/*#write for the workspace’s default project and #limit permission for each created namespace. See Root key permissions.
