Labels and barcodes over REST

Labels in, barcodes out. No printer required.

Two ways in

Whole labels or single symbols, drawn by the same engine — so a barcode looks identical whether it arrives inside a label or on its own.

Send ZPL

Label rendering

Post a ZPL stream, get the label back as PNG or PDF. Multi-label formats page through by index, stored formats recall with ^XF, and an unsupported command is reported rather than failing the render.

Barcode generation

One symbology and a payload, no ZPL required. The response is cropped to the symbol, so it drops straight into a document, a portal or a label you are laying out yourself.

Open the generator

38 symbologies

29 linear and 9 two-dimensional, each with its own input rules and check digits. Plus 14 content types that format the payload — contacts, Wi-Fi, calendar events, payment requests.

Built for label work

Debug templates without a printer

See what a label actually looks like before it reaches a print server, including barcode geometry and field wrapping.

Linter warnings, not failures

An unsupported command is reported and skipped rather than failing the render, so one odd field never costs you the whole label.

Options that apply, and only those

A bar width ratio means nothing to Code 128, and guard bars exist only on retail codes. Ask for one anyway and it is ignored and reported, never refused — so a shared link survives a change of symbology.

Check digits computed, not assumed

EAN, UPC, ITF-14, SSCC and PZN all calculate their own check digit, and the printed line shows it. Over-long input is refused rather than quietly truncated into a different product code.

Content types, not forty barcode types

A vCard QR is a QR code; so is a Wi-Fi credential or a payment request. Pick a content type and the payload is built and escaped for you.

Stored formats

Download a format once with ^DF and recall it per parcel with ^XF and ^FN field data, exactly as a printer would.

Two calls

A whole label, from ZPL

curl -X POST --data-binary @label.zpl \
     -H "Accept: image/png" \
     https://api.arkalabel.io/v1/printers/8dpmm/labels/4x6/0/ \
     -o label.png

One barcode, from a URL

curl "https://api.arkalabel.io/v1/barcodes\
?type=code128&data=ARKA-123456789" \
     -o barcode.png
