Preview DKIM verification of a billing email without creating a spend or earning sats. Returns extracted invoice data (vendor, amount, date, DKIM status). The full email is required because DKIM signatures are computed over the original RFC 2822 message bytes — the signature cannot be verified without them. The email is discarded after verification.

| Property | Type | Required | Description |
|---|---|---|---|
