Frequently Asked Questions
How do I generate code 11 barcode as SVG with an API?
Send a request to the ChartQuery barcode endpoint with format: "svg" in your JSON body (POST) or as a query parameter (GET). The API returns a SVG file directly in the response body. No API key is required for basic usage.
Why choose SVG over other output formats?
Infinitely scalable vector format for web, print, and high-resolution output. SVG files are also smaller than raster formats and can be styled with CSS when embedded in HTML.
What is the maximum resolution for SVG output?
SVG is a vector format, so resolution is infinite. The output scales to any size without quality loss.
Is the SVG code 11 barcode API free?
Yes. Anonymous access gives you 60 requests per hour without an API key. A small watermark is added to free-tier output. Paid plans remove the watermark and increase rate limits.
Can I embed SVG code 11 barcode in emails and documents?
SVG can be embedded directly in HTML pages and some email clients, but many email clients (Gmail, Outlook) strip SVG. Use PNG for email embedding.
What content type does the API return for SVG?
The API returns image/svg+xml in the Content-Type header. The response body is the raw SVG file data, ready to save to disk or stream to the client.
