Verify a batch of US or Canadian addresses in a single request. Each address can be freeform or structured, matching the same input formats accepted by the single verification endpoint.

• Uses 1 lookup per address (plus 1 more per address if geocoding).
• Requires a secret API key.
• Returns results in the same order as the input addresses.
• If an individual address fails, its result will contain an error field rather than a verifiedAddress.
