Qr Agent Core tools 37
create_qr_codeCreate a new managed QR code with optional custom styling. The QR code points to a short URL that redirects to your target URL. You can change the target URL later without regenerating the QR image. Supports custom colors, dot shapes, corner shapes, and logo embedding.get_qr_codeRetrieve details of an existing QR code by its short ID. Returns the current target URL, metadata, and timestamps.update_qr_destinationChange where an existing QR code redirects to. This is the key 'dynamic link' feature: the QR image stays the same, but scanning it will now go to the new URL. Ideal for updating campaigns, fixing broken links, or A/B testing.list_qr_codesList all managed QR codes with pagination. Returns short IDs, target URLs, labels, and timestamps. Use this to browse or search for existing QR codes.delete_qr_codePermanently delete a QR code and all its scan analytics. The short URL will stop working immediately. This cannot be undone.get_qr_analyticsGet enriched scan analytics for a QR code. Returns total scans, daily trends, device/browser/country/referer breakdowns with percentages, and recent scan events with parsed user-agent and geo data.bulk_create_qr_codesCreate multiple QR codes in a single request (up to 50). Each item supports the same options as create_qr_code. The quota check is all-or-nothing: if the batch would exceed your plan limit, no QR codes are created. Ideal for generating QR codes for product catalogs, event lists, or batch operations.bulk_update_qr_codesUpdate multiple QR codes in a single request (up to 50). Change target URLs and/or labels. Items with non-existent short_id are reported as not_found without failing the whole batch.bulk_delete_qr_codesDelete multiple QR codes and their scan analytics in a single request (up to 50). Items with non-existent short_id are reported as not_found without failing the whole batch.create_vcard_qrCreate a QR code that encodes a contact card (vCard). When scanned by a phone camera, it prompts the user to save the contact. Supports all standard vCard fields and custom QR styling.create_wifi_qrCreate a QR code that encodes WiFi credentials. When scanned by a phone camera, it offers to auto-join the WiFi network. No internet connection needed to join — the credentials are encoded directly in the QR image.update_vcard_qrUpdate the contact details of a vCard QR code. Only works on QR codes created with type='vcard'. Partial updates merge with existing data. Note: updating vCard data changes the QR image content.- +25 more on the listing page
