  28. 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).

  32. 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.
