How this service works
Generate a barcode as SVG (EAN-13, EAN-8, UPC-A, ISBN, ISSN, Code 128, Code 39, ITF, GS1-128...) for labels and products, computing the check digit when missing.
Output
Returns a JSON object containing the barcode type used, the complete barcode code (including computed check digit), the SVG image as a base64 string, a ready-to-embed data URI (data:image/svg+xml;base64,...), and the file size in bytes.
Example use cases
Product label barcode generation
“I need an EAN-13 barcode SVG for my product with code 5901234123457 — make sure the human-readable number is shown underneath the bars.”
Book ISBN barcode for publishing
“Can you create an ISBN-13 barcode in SVG format for the code 9780306406157? I need it for the back cover of a book.”
Shipping label with Code 128
“Generate a Code 128 barcode SVG for the tracking number 'SHIP-20240612-XYZ99' to print on a shipping label — no visible text needed.”

Endpoint
POSThttps://api.vextorium.com/generar-codigo-barras-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need server-side, scalable barcode SVG generation without installing local libraries, especially when check-digit computation is needed or when integrating barcode creation into an automated label-printing or product-management workflow. Ideal for agents that need a vector (SVG) output suitable for both screen display and high-resolution printing.
Side effects
- Invalid or malformed barcode code for the selected symbology returns an error
- Barcode type string does not match a supported symbology name
- Code length mismatch for fixed-length formats like EAN-13 or EAN-8
- Missing required 'codigo' field results in validation error
- Unsupported combination of type and code content
