Stt API
Takes an audio or video file by URL or inline base64 and returns the transcript: the full text, every word with start and end time and its own confidence, the utterances and paragraphs the recogniser separated, and the detected language with its confidence where no language was specified.
halowerk.com-$0.06listed
Stt Batch API
Takes 2 to 15 recordings by URL or inline base64, each with its declared length, and returns one transcript per file in the order given: full text, detected language, paragraphs, utterances, a confidence summary naming the weakest words with timestamps, and optionally every word with its timing. Billing is per started audio minute across the whole batch, at 0.017 USDC instead of the 0.02 USDC of a single /v1/stt call, at most 60 minutes per call.
halowerk.com-$0.034listed
Stt Long API
Takes a public URL of an audio or video file of up to 120 minutes and 150 MB and returns the transcript: full text, paragraphs with sentences and timings, utterances, the detected language, and a confidence breakdown naming the weakest words with timestamps; every word with its timing on request. The file is downloaded and its running time measured locally with ffprobe before anything is sent, so a recording longer than declared is refused with its real length and nothing is charged.
halowerk.com-$0.018listed
Stt Translate API
Takes an audio or video file by URL or inline base64 and returns subtitles in the target language with the timing of the original speech. The recording is transcribed with word timestamps, split into subtitle cues at pauses, six seconds or 84 characters, and every cue is translated on its own so that the number and timing of cues stay identical — this is checked on every model answer and a mismatch is retried once and otherwise refused without charge.

Line breaks inside a cue are joined for translation. Output in SRT or WebVTT. Translation by a language model at Groq, which does not train on inputs; disclosed in the answer. Machine translation, unreviewed.
