> ## Agent Instructions
> Unkey is two separate products. Compute builds, deploys, and runs apps behind a gateway. API Management issues API keys, enforces rate limits, manages identities and permissions, and reports usage. Say which product a page belongs to; a reader can use either without the other.
> Every Unkey API endpoint is an HTTP POST to https://api.unkey.com/v2/{service}.{procedure} with a root key in the Authorization: Bearer header. Root keys are workspace scoped.
> Error codes have the form err:{system}:{category}:{specific} and each has a page at /errors/{system}/{category}/{specific}.
> The word environment means production or preview in Compute. Rate limiting has four meanings on this site; the glossary lists them.

# unkey api ratelimit multi-limit

> Check several rate limits in one request that passes only if all of them pass.

<Note>
  You need a root key with the permissions listed on this page. Create one in the dashboard under **Settings > Root Keys**. See [Permission reference](/docs/platform/root-keys/permissions-legacy) for every permission.
</Note>

Check several <Tooltip tip="Here: the standalone rate limiting API and its overrides. Not key rate limits or gateway policies.">rate limit</Tooltip>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`](/docs/errors/unkey/data/ratelimit_namespace_gone). Calls `POST /v2/ratelimit.multiLimit`. See [Limit and multi-limit](/docs/api-management/ratelimiting/limit-and-multi-limit).

## Usage

```bash theme={"system"}
unkey api ratelimit multi-limit --limits=<limits> [flags]
```

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

## Flags

<ParamField body="--limits" type="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.
</ParamField>

### Shared flags

Every `unkey api` command takes these. See [CLI output and shared flags](/docs/platform/cli/output-and-flags).

<ParamField body="--root-key" type="string">
  Root key used for the request. Falls back to `UNKEY_ROOT_KEY`, then to the key stored by `unkey auth login`.
</ParamField>

<ParamField body="--api-url" type="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.
</ParamField>

<ParamField body="--config" type="string" default="~/.unkey/config.toml">
  Path of the config file written by `unkey auth login`. Falls back to `UNKEY_CONFIG`.
</ParamField>

<ParamField body="--output" type="string">
  Output format. Falls back to `UNKEY_OUTPUT`. `json` prints the full response. Any other value prints the request ID and `data`.
</ParamField>

<ParamField body="--body" type="string">
  Send this JSON as the whole request body instead of using the command's flags. You can't combine it with them.
</ParamField>

## Required permissions

`ratelimit.*.limit`, or `ratelimit.<namespace_id>.limit` for every namespace in the request. Namespaces created on first use also need `ratelimit.*.create_namespace`. See [Root key permissions](/docs/platform/root-keys/permissions).

## Examples

```bash Two limits theme={"system"}
unkey api ratelimit multi-limit --limits='[{"namespace":"api.requests","identifier":"user_abc","limit":100,"duration":60000},{"namespace":"api.daily","identifier":"user_abc","limit":5000,"duration":86400000}]'
```

Or send the whole request as JSON:

```bash Raw body theme={"system"}
unkey api ratelimit multi-limit --body='[{"namespace":"api.requests","identifier":"user_abc","limit":100,"duration":60000}]'
```
