mobile_call_ai_contact_search_too_short
The Mobile Call AI contact search needs at least two characters; a phone number or email address is not a searchable label.
Problem shape
Every non-2xx response is an RFC 9457 application/problem+json body. The type URI below is stable and machine-matchable, so branch on the final path segment (the code) and treat the status as redundant confirmation. See the error-handling guide.
