Build a workflow around files you can inspect
The assistant is an interactive file-workflow tool. Its internal chat endpoint is not presented as a stable public developer API.
Lyric alignment API documentationThis guide is in English. The assistant supports 83 interface languages.
Use exported files as the handoff
Choose a documented format your next system understands. JSON is useful for structured timing data, CSV for a spreadsheet handoff and subtitle formats for caption consumers. Inspect the actual output rather than assuming every source preserves identical fields in every format.
Keep word alignment with its own API
For programmatically aligning supplied lyrics to audio, see the LyricTimestamps API documentation. It describes that product's inputs, job status and outputs. MusicTimestamps does not rebrand that endpoint as a separate alignment API.
Discuss an integration before depending on it
For automation or a new export target, contact the operator with your input format, expected output and how the next application consumes it. Avoid placing production dependencies on undocumented browser or chat requests.
