shared_phone_payment_verification_required
Current provider payment evidence could not be verified and no unexpired verified observation is available. Resolve the billing connection or retry after provider recovery; this refusal does not establish that a charge failed.
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.
