# Rate limits

Limits are applied per API key and reset on a rolling 60-second window.

| ENDPOINT TYPE                 | SANDBOX | GROWTH  | ENTERPRISE |
| :---------------------------- | :------ | :------ | :--------- |
| `TTS (characters / min)`      | 5,000   | 100,000 | Custom     |
| `Audio Processing (min / hr)` | 10      | 500     | Custom     |
| `Agent Concurrent Sessions`   | 5       | 100     | Custom     |

When you exceed a rate limit, the API returns `429 Too Many Requests` with a `Retry-After` header. Enterprise plans include dedicated capacity with guaranteed throughput SLAs.
