Confusable / homoglyph spoof detector API

Reduce text to its Unicode confusable 'skeleton' (mapping Cyrillic/Greek look-alikes, full-width forms and digit/letter swaps to Latin prototypes), report the scripts present, whether it mixes scripts, and a spoof flag — the IDN-homograph / lookalike-domain attack signal — plus an optional comparison to a target string. Answers 'is this a homoglyph spoof', 'does аpple.com spoof apple.com', 'is this domain a lookalike', 'what scripts are in this string'.
