Duration, codec, bitrate, channels and any tags the file carries.
Report duration, codec, bitrate, sample rate, channel layout and embedded tags via ffprobe.
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.
