Operations 7

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

POST /v1/flows/text-to-speech Queue an asynchronous speech generation job · Create Speech Generation #
Ask an LLM
“Is there an asynchronous alternative to generating speech in a single request?”
“Can I use a speech model that's only available through the generation lifecycle?”
Tell an agent
Queue an asynchronous speech generation.
Create a speech generation job to poll later instead of synthesizing inline.
GET /v1/flows/text-to-speech List queued asynchronous speech generations · List Speech Generations #
Ask an LLM
“Where can I see the asynchronous speech generation jobs I've queued?”
“Can I list only the queued speech jobs that are still in progress?”
Tell an agent
List my asynchronous speech generation jobs.
Show queued speech jobs with status {status}.
GET /v1/flows/text-to-speech/{generation_id} Get a queued speech generation's result · Get Speech Generation #
Ask an LLM
“Has my queued speech job finished, and where's its output?”
“How do I poll a speech generation job for its audio URL?”
Tell an agent
Poll speech generation job {generation_id}.
Fetch the result URL of queued speech job {generation_id}.
POST /v1/text-to-speech/{voice_id} Convert text to speech in one response · Text To Speech #
Ask an LLM
“How do I turn a paragraph of text into an MP3 with a specific voice?”
“Can I get the same audio twice by passing a seed?”
Tell an agent
Say {text} in voice {voice_id}.
Generate speech for {text} with voice {voice_id} as {output_format}.
POST /v1/text-to-speech/{voice_id}/with-timestamps Generate speech with word-level timings · Text To Speech With Timestamps #
Ask an LLM
“How can I highlight words on screen in sync with generated speech?”
“Does text-to-speech return timing for each word along with the audio?”
Tell an agent
Generate speech for {text} in voice {voice_id} with word timestamps.
Voice {text} with {voice_id} and return per-word timing for captions.
POST /v1/text-to-speech/{voice_id}/stream Stream text-to-speech audio for low latency · Text To Speech Streaming #
Ask an LLM
“What's the best way to start playing speech before the whole clip is generated?”
“Can text-to-speech audio arrive in chunks for real-time playback?”
Tell an agent
Stream {text} as speech in voice {voice_id}.
Stream audio of {text} from voice {voice_id} in format {output_format} for live playback.
POST /v1/text-to-speech/{voice_id}/stream/with-timestamps Stream speech with word-level timings · Text To Speech Streaming With Timestamps #
Ask an LLM
“Can I stream audio and get word timestamps at the same time?”
“How do I build live karaoke-style captions from streamed speech?”
Tell an agent
Stream {text} in voice {voice_id} with word timestamps.
Stream speech and word timing for {text} using voice {voice_id} and language {language_code}.
