Notes

• The zelfQR field contains a base64-encoded PNG QR code image
• The QR code can be displayed directly in applications or saved as an image file
• IPFS data includes metadata about the stored proof and public data keys
• Credits are deducted for proof creation (typically 0.84 credits)
• The identifier must be alphanumeric only (no spaces or special characters)
• publicData and metadata must contain only string key-value pairs
• QR codes are ideal for offline sharing and mobile applications
• The QR code contains the same encrypted proof data as the regular encrypt endpoint
