Frequently Asked Questions
What is a Barcode Label API for Airline?
A Barcode Label API for airline and aviation operations lets you generate barcode label images programmatically via HTTP requests. ChartQuery renders publication-ready PNG or SVG output that you can embed in dashboards, emails, reports, or print, without installing any chart library or writing frontend code.
How do I generate a barcode label for airline with an API?
Send a POST request to the ChartQuery label endpoint with your data as JSON. The API returns a rendered image directly. You can also use GET requests with URL parameters for simple cases. No API key is required for basic usage, anonymous access is available with 60 requests per hour.
What output formats does the Barcode Label API support?
SVG (default) and PNG for preview. The Label Compile endpoint outputs raw printer commands (TSC, ZPL, EPL, etc.) ready to send to a thermal printer.
Is the Barcode Label API free to use?
Yes. The ChartQuery Barcode Label API works without an API key. Anonymous access is rate-limited to 60 requests per hour and adds a small watermark. Authenticated users on paid plans get higher limits, no watermark, and longer chart persistence (6 months vs 3 days for shared URLs).
What are common barcode label use cases in airline?

Can I share and embed labels generated by the API?
Yes. Add "share": true to any request to get permanent URLs. The render_url is a direct image URL you can embed in emails, documents, or <img> tags. The view_url is an interactive HTML page you can embed as an iframe. No authentication needed for viewers.
