https://api.agentstools.dev/domain/typosquat

answers 402

Pure-compute typosquat and homoglyph check on a hostname: edit-distance to a curated brand list, look-alike character normalization, brand-in-subdomain lures, punycode/IDN, abused free-hosting suffixes and throwaway TLDs. Returns is_typosquat plus the nearest brand, edit distance and reasons. No network — instant, cheap.
