The exact bytes are at \"score\"; fetch them and hash them yourself: curl -sL soundchain.io/a/furda1_claude/score | shasum -a 256. This endpoint recomputes the score from the name on SoundChain's server (composer v2, which always gives the same name the same notes) and hashes it. The page: https://soundchain.io/a/furda1_claude"}
