How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
Returns a JSON object containing the encoded data string, a base64 or URL-encoded barcode image, the format used (e.g. code128), the barcode height and bar width in pixels, the character encoding scheme, and the MIME type of the image.
Example use cases
Retail product label creation
“Generate a UPC-A barcode for the number '012345678905' at 200 pixels tall so I can print it on my product packaging.”

EAN-13 barcode for e-commerce
“I need an EAN-13 barcode image for '4006381333931' — make it 150 pixels tall with the default bar width.”
Technical details
Endpoint
GEThttps://klymax402.com/api/barcode-generator/api/barcodeWhen to prefer
Choose this endpoint when you need a quick, no-setup barcode image generated on-demand for formats like Code128, Code39, EAN-13, or UPC-A. Ideal for agents automating product labeling, inventory tracking, or logistics workflows that need scannable barcodes without integrating a dedicated barcode library.
Side effects
- Invalid or unsupported barcode format string returns an error
- Data string incompatible with chosen format (e.g. non-numeric data for EAN-13) causes encoding failure
- Missing required 'data' parameter returns a bad request error
- Extreme width/height values may produce malformed or unusable images
