To ensure fair usage, this streaming endpoint is subject to more strict rate-limits and also limits the text size it may take as input. Input text provided to the streaming endpoint may contain at most 20 sentences. A sentence is defined as a sequence of at least 35 characters separated by a punctuation character (., ? or !). Maximum text length is 2000 characters.

The endpoint responds with a byte audio stream right away:

• Status: 200 - OK
• Body: audio bytes

If the accept header is application/json, the endpoint returns data containing an URL that is immediately streamable:

• Status: 201 - CREATED
• Body:
  JSON
