Bolt Phone Validate

Use this endpoint when you need to validate or verify a phone number's format, carrier, or reachability before using it for communication or onboarding. Prefer this over regex-only validation when you need carrier-level or line-type data. Good for pre-flight checks before SMS campaigns or user registration flows.

• Invalid or missing phone field returns error
• Malformed phone string that cannot be parsed yields success: false
• Unsupported country code may return incomplete metadata
• Network or service timeout returns HTTP error
• Insufficient USDC balance or x402 payment failure blocks the request
