Supertone API operates request rate limit policies to prevent excessive usage and ensure stable service operation.

1. Request Rate Limit Policy

Request rate limits are applied according to your account tier:

TierRequests per Minute
Free & Starter20 requests / minute
Creator30 requests / minute
Pro60 requests / minute

These limits apply uniformly across all API endpoints, including voice queries, text-to-speech conversion, usage tracking, and more.

2. When Limits Are Exceeded

If the number of requests exceeds the allowed rate, the API will return a 429 Too Many Requests error.

Please wait a moment and try your request again.

In some cases, temporary throttling or blocking may be applied to prevent system overload.
Note that actual behavior may vary depending on the situation, and some responses may be delayed or dropped without prior notice.

3. Need Higher Rate Limits?

If you need to make API requests more frequently, you can apply more flexible request rate limit policies through an Enterprise Plan or a separate contract.
Rate limit conditions can be adjusted based on your operating environment and service characteristics.
