Structured Address — Verify and standardize a structured address (e.g., with line1, city, etc.).
Freeform Address — Verify and standardize a freeform address written on one line. For best results, append the ISO 2-letter country code (e.g., US, CA) to the end of the line.

Specifying includeDetails=true will provide additional output as documented in the Details schema.
