Take a clip out of an audio file

curl -X POST "$DOATHING_API/v1/media/audio-sample" \
  -H "x-api-key: $DOATHING_KEY" \
  -H "content-type: application/json" \
  -d '{"file": {"filename": "recording.mp3", "content_type": "audio/mpeg", "data_b64": "<base64>"}, "options": {"start": 30, "duration": 15}}'

Pull a fixed-length sample from any point in a longer recording.

Extract a fixed-length audio sample starting at a given offset.

Input

Send a file object with base64 data_b64, its content_type and a filename. Accepted types: audio/mpeg, audio/wav, audio/ogg, audio/flac, audio/mp4.

The declared type is not trusted — the bytes are sniffed and a contradiction is rejected rather than corrected.

Response

The result carries your remaining balance alongside it, so you can track spend without a second call.

Cost

5 credits per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.

A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.
