Fundable / Unlock a person's verified phone number by identifier

Use this endpoint only when a verified phone number is explicitly required for an identified person. Return a verified phone number for a person identified by UUID, LinkedIn, Crunchbase, or Twitter/X. Provide one identifier. If multiple identifiers are supplied, the endpoint uses the first non-empty value in this order: id, linkedin, crunchbase, twitter. A newly created unlock costs 5 credits. Repeating the request for a phone number the same account already unlocked costs 0 credits. Unlock ownership persists across API keys belonging to that account. Provider attribution is internal and is not returned. Available on non-trial Pro+, Enterprise, and API plans.
