To prevent abuse, our APIs are rate-limited. The specific limits depend on the API you are using and the plan you are on.
Limits are specified on the table below.
requests/m means maximum number of allowed requests in a minute, and chars/m means maximum number of characters per minute. For endpoints that have both requests/m and chars/m, the calls will be limited when any of those limits is reached.

Limits for the Standard & Premium Voices APIs
The conversion endpoint (POST /v1/convert ) is rate-limited to 50 requests per minute.
How are rate limits calculated?
Our API rate limit is based on the number of requests being sent within the same minute.
What happens if I hit my rate limits?
If you exceed your API rate limits, your requests will be met with an error response indicating a 429 HTTP status code. This means you have exceeded the maximum number of requests allowed for the minute. You can make new requests after a short waiting period of no more than a minute.
Can I increase my rate limits?
Yes. It is configurable per client. Please reach out using our contact page so we can better understand your use case and devise the best strategy for you.
