API Specifications

Rate Limiting

Usage, such as making highly concurrent API calls, may result in your app being rate limited. The WellSaid API is currently limited to 3 requests / 1 second, along with your monthly quota. For higher concurrency, please reach out to WellSaid to discuss different plans.

Requests made to the WellSaid API will return the following HTTP response headers:

x-quota-limit: The maximum number of requests available in the current time frame.
x-quota-remaining: The number of requests remaining in the current time frame.
x-quota-reset: A UNIX timestamp of the expected time when the quota limit will reset.
x-rate-limit-limit: The maximum number of requests available in the current time frame.
x-rate-limit-remaining: The number of requests available in the current time frame.
x-rate-limit-reset: A UNIX timestamp of the expected time when the rate limit will reset.

We have higher rate limit configurations available. Please ask your voice specialist for more information.

Time to first Byte

WellSaid API returns a stream of an audio file as a response, not the actual file itself. The Time to First Byte is 500ms on the 95th percentile on API calls with around 30 characters.
