## Live Policy Update via Admin API

Routiium allows for live updates to rate limit policies and assignments without requiring restarts.

### Create a New Policy

Use a `POST` request to create a new rate limit policy.

```bash
curl -X POST http://localhost:8088/admin/rate-limits/policies \
  -H "Authorization: Bearer $ROUTIIUM_ADMIN_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"id":"beta","buckets":[{"name":"daily","requests":2000,"window_seconds":86400}]}'
```

### Assign Policy to a Key

Assign a created policy to a specific key (e.g., an API key).

```bash
curl -X POST http://localhost:8088/admin/rate-limits/keys/sk_abc123.xyz \
  -H "Authorization: Bearer $ROUTIIUM_ADMIN_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"policy_id":"beta"}'
```

### Check Key Status

Retrieve the current rate limit status for a specific key.

```bash
curl http://localhost:8088/admin/rate-limits/keys/sk_abc123.xyz \
  -H "Authorization: Bearer $ROUTIIUM_ADMIN_TOKEN"
```

### Emergency Block

Temporarily block a key for a specified duration.

```bash
curl -X POST http://localhost:8088/admin/rate-limits/emergency \
  -H "Authorization: Bearer $ROUTIIUM_ADMIN_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"key_id":"sk_abc123.xyz","duration_secs":3600,"reason":"abuse detected"}'
