ApexAPI Geo Address Validator

Use this endpoint when you need to confirm that a physical mailing or shipping address is real and deliverable before storing it, sending mail, or completing a checkout flow — particularly when you want a pay-per-call model with no API key setup. Prefer this over form-level regex validation when actual existence verification matters.

• Malformed or empty query string returns a validation error
• Address not found in reference database returns invalid/undeliverable status
• Ambiguous address with multiple matches may return low-confidence result
• Payment failure via x402 results in 402 response before processing
• Service timeout or upstream geo data unavailability causes 5xx error
