MP3 to SRT, with an API call

Send an audio file or URL and download a ready-to-use .srt file. Cues are built from word-level timestamps and broken at natural pauses — two lines, readable length — not dumped one sentence per cue.

The whole integration

bash

# 1. start the job
ID=$(curl -s -X POST https://api.audiotranscribr.com/v1/transcriptions \
  -H "x-api-key: $KEY" \
  -d '{"url": "https://audiotranscribr.com/samples/clip-22-451-01.mp3"}' | jq -r .id)   # a 1-minute sample we host; use any direct media URL

# 2. wait until it is done
until [ "$(curl -s https://api.audiotranscribr.com/v1/transcriptions/$ID -H "x-api-key: $KEY" | jq -r .status)" = "completed" ]; do sleep 3; done

# 3. download the subtitles
curl -sL "https://api.audiotranscribr.com/v1/transcriptions/$ID/result?format=srt" -H "x-api-key: $KEY" -o episode.srt

For a file on disk, leave out url: the response includes an upload link to PUT the file to. Works the same for M4A, WAV, FLAC, OGG and video files.
