How this service works
Generate a 1D barcode as PNG or SVG: EAN-13, EAN-8, UPC-A, Code 128, Code 39 or ITF-14. Validates the structure and check digit for each symbology — EAN/UPC/ITF compute a missing check digit or reject a wrong one. Options: format (png/svg), scale (module px 1-10), text (human-readable line, default on). Returns the raw image. Generation only — reading a barcode from an image is out of scope.
Output
Returns the raw barcode image file — either a PNG binary or an SVG document — ready to embed, display, or print. For EAN/UPC/ITF symbologies, a missing check digit is computed automatically; a wrong one is rejected with an error.
Example use cases
Example prompt
“Generate an EAN-13 barcode for the value 590123412345 as a PNG with scale 4 and the human-readable number shown underneath.”
Technical details
Endpoint
POSThttps://402utils.com/v1/barcodeWhen to prefer
Use this endpoint when you need server-side barcode image generation with automatic check digit computation and validation for standard retail/logistics symbologies (EAN, UPC, ITF-14, Code 128/39). Prefer this over client-side libraries when you need a clean hosted API with per-call pricing, or when you want guaranteed check digit correctness without implementing the logic yourself.
Side effects
- Invalid check digit provided — endpoint rejects and returns error
- Data string contains characters unsupported by the chosen symbology (e.g. lowercase for Code 39)
- Data length mismatch for fixed-length symbologies (EAN-13 requires 12 or 13 digits)
- Scale out of range (must be 1–10) — validation error
- Unknown symbology value — returns 4xx error
- Payment failure — x402 payment not accepted or insufficient USDC balance
