  18. 95api.duoleads.com/v1/code/idnConvert internationalised domain names between Unicode and ASCII punycode in either direction, label by label, and validate each label against IDNA2008: length, leading and trailing hyphens, the hyphen-hyphen rule at positions 3 and 4, disallowed code points and bidirectional rules. Returns both forms, the per-label breakdown and the first rule violated. Strict mode is IDNA2008 (UTS 46 non-transitional); it may reject names /v1/code/url displays.$0.05 Base733 ms1 payers100% up
  19. 95api.duoleads.com/v1/code/urlParse and canonicalise a URL, and extract its registrable domain using the Public Suffix List — the part an agent needs to decide whether two URLs belong to the same owner.

Returns per-character detail with code points, names and the ASCII character each imitates.$0.05 Base409 ms1 payers100% up
  22. 95api.duoleads.com/v1/text/slugTurn arbitrary text into a URL-safe slug. Decomposes accents, transliterates German umlauts, Scandinavian and Turkish letters, the ligatures that lose meaning under plain NFD, and Cyrillic (Russian, Ukrainian, Belarusian, Bulgarian, Serbian, Macedonian; language from lang or inferred from the letters).

  26. 95api.duoleads.com/v1/time/zoneConvert an instant to wall-clock time in a named IANA time zone, or a wall-clock time in a zone back to an instant.
