The lightest existence probe: pass a target and get back whether it is registered on Snapchat. A username-shaped target (e.g. teng_leo) is resolved against the public profile surface; an email address is checked via an account-recovery probe. exists is three-state: true = registered, false = not registered, null = undetermined (transient — see message, cool down, and retry). Ideal for real-time form validation and availability checks. Note: a positive email result may send a real recovery email to the address owner, so do not use this to spray large email lists.
