Validate Address

Standardize and verify a free-form US shipping address via the Google Address Validation API. Returns USPS-standardized components (street / unit / city / state / ZIP), a confidence verdict (high / medium / low), whether Google corrected anything, and which components are missing. Ideal for: confirming a deliverable address collected in chat before placing an order, surfacing the corrected form for the user to approve rather than re-type.
