Results come from the same music-theory module the browser's Key Assistant and Chromatic Grid use, and report where the analysis is uncertain instead of guessing.

Pass the same idempotency_key when retrying so an uncertain attempt cannot leave duplicate sessions behind.

A successful call includes a backwards-compatible compact snapshot plus an acknowledgement. That snapshot is not authoritative verification; do not make another edit or finish from it. Read with get_session next. Supported operations: add_track, set_track_instrument, set_track_pan, set_steps, and set_tempo. set_steps changes only the named steps; it never replaces a track or session. set_track_instrument replaces only a track's sound source, keeping its pattern, mix, timing, and custom name.

The result lists any session features a MIDI file cannot carry rather than approximating them silently.

Only call this when someone explicitly asks to publish; it is never a side effect of editing or exporting.
