Send a GET to /v1/youtube/video/audio with the video url. The response lists the downloadable audio streams, each with a direct media URL, mime type, bitrate, audio quality, sample rate, and channels. ### Are the audio stream URLs permanent? No. The stream URLs are time-limited, so fetch the file immediately and do not cache the URL, which stops working after it expires. ### What audio details come back per stream? Each stream includes its direct URL, mime type, bitrate, audio quality label, sample rate, channels, and approximate duration, so you can pick the format you need. ### How much does the audio files endpoint cost? It is an advanced endpoint. Every new account starts with 100 free credits, so you can test it without adding a card. ### How is this different from the transcript endpoint? The transcript endpoint returns spoken text, while video/audio returns the actual downloadable audio stream files. Use audio when you need the sound, not the words.
