## Tools (11)

- `account_status`: For a connected Starchild member: their credit balance. Making a new version costs 2 credits per style (3 for songs over 3:30).
- `build_cart`: Turn chosen songs and licenses into one link that opens the person's Starchild cart with everything already added. Checkout happens on starchild.music. Use license ids from license_options (e.g. song-only, song-instrumental, royalty-free, exclusive-license).
- `change_style`: Hear a Starchild song in a different production style (for example Country, Acoustic Indie, Electro Rock, Latin Salsa, Piano Ballad Orchestral). Returns a link that opens the song on starchild.music set to that style, with the original vocal. Lists the available styles if the requested one isn't made for this song.
- `check_transform`: For a connected Starchild member: progress and listening links for a transform started with transform_song.
- `get_song`: Full details for one Starchild song: writers, genres, moods, key, tempo, every production style, sounds-like, similar songs, and which licenses are available. Accepts the song id, its starchild.music link, or its exact title.
- `how_to_sell_songs`: For songwriters and catalog owners: how to list original songs on Starchild, what it costs, how licensing earnings are paid, and who keeps the rights.
- `license_options`: What licensing a Starchild song costs. With a song, returns exactly which licenses and add-ons that song offers and their prices. Without one, returns the standard price list. All prices are one-time, in US dollars.
- `play_song`: Play a Starchild song: shows an in-chat player with the original recording and every production style made for it (same vocal; switch styles mid-song), plus starchild.music links for each style.
- `search_songs`: Search Starchild's catalog of original songs by meaning: describe the song in plain words (e.g. 'uplifting country ballad about starting over, female vocal'). Optional filters narrow by genre, mood, vocal or tempo. Shows an in-chat browser where every result plays, in every production style, with more results on request (use offset).
- `transform_song`: For a connected Starchild member: render NEW versions of a catalog song in chosen production styles, keeping the original vocal, using their credits (2 per style, 3 per style for songs over 3:30). Optional creative direction in plain words. Takes a few minutes; returns a job id for check_transform. Results also save to the member's Gen library on starchild.music. Use change_style first for styles that already exist (free).
- `verify_certificate`: Check whether a Starchild license certificate number (format SC-2026-123456) is genuine, and which song and license it covers.
