Passport Data Extraction
Passport Data Extraction API for MRZ and VIZ Fields
StructOCR processes passport bio-data pages by combining Machine Readable Zone (MRZ) extraction with Visual Inspection Zone (VIZ) reading. Send a Base64-encoded image or PDF and receive structured passport data through a single JSON API response.
VIZ Field Extraction
Reads the visual inspection zone for fields that may not appear in the MRZ, including place of birth, date of issue, and issuing authority.
Normalized JSON Output
Returns consistent field names and ISO-formatted dates so passport data can move directly into KYC, travel, or onboarding workflows.
