## Tools (4)

- `get_screening`: Fetch the status and result of one screening. When status is COMPLETED, returns every window where a commercial recording was detected, with timestamps and the matched title/artist, plus a plain-language verdict on whether the file is safe to publish.
- `list_screenings`: List the most recent screenings on the account that owns the API key, with their results and the remaining credit balance.
- `screen_audio`: Submit a publicly reachable audio or video URL for copyright screening. Returns immediately with a report_id and QUEUED status — call get_screening to poll for the result. Costs credits from the account that owns the API key (1 credit per sampled window). Run this BEFORE publishing generated content.
- `verify_report`: Check that a MusicCheck report id refers to a real screening, and see what it concluded. Needs no API key — anyone can verify a report someone else shows them. Use this to check a claim of "already cleared".
