## Verify

**post** `/v1/addver/verifications`

1. **Structured Address** — Verify and standardize a structured address (e.g., with `line1`, `city`, etc.).
1. **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.
