zpl_previewRender ZPL label code and return the label as a PNG image. Use this to SEE what ZPL output looks like — LLMs can write ZPL but cannot otherwise verify the visual result. One call renders one label (use `index` to pick a label from a multi-label stream). The result also carries a…
zpl_validatePass/fail lint for ZPL — machine-readable diagnostics with line/column, code and severity: unknown commands, missing ^FS, out-of-range parameters, fields outside the label. Fast; run it before zpl_preview whenever you generate or edit ZPL. For a human-readable report with a scor…
zpl_command_helpExplain a single ZPL command: syntax, parameters with types/ranges/options, a fragment example and whether the Labelixa renderer draws it. Data comes from the same catalog that powers the public command reference pages.
barcode_pngGenerate a single barcode as a PNG image (Code 128, QR, DataMatrix, EAN-13, UPC-A, PDF417 and more). For a full label with text and layout, write ZPL and use zpl_preview instead.
language_detectDetect which printer language raw label code is written in (ZPL, EPL, TSPL or CPCL). Heuristic: returns the language plus a confidence TIER (high/medium/low) and signal codes — not a probability.
epl_validateLint EPL/EPL2 label code and return positioned findings with severity as JSON. Checks the command set Labelixa implements from the EPL2 manual — a clean result is not a guarantee that a specific printer accepts the job. Run this before epl_preview; if you are not sure which lang…
tspl_validateLint TSPL/TSPL2 label code and return positioned findings with severity as JSON. Checks the command set Labelixa implements from the TSPL2 manual — a clean result is not a guarantee that a specific printer accepts the job. Run this before tspl_preview; if you are not sure which…
cpcl_validateLint CPCL label code and return positioned findings with severity as JSON. Checks the command set Labelixa implements from the CPCL manual — a clean result is not a guarantee that a specific printer accepts the job. Run this before cpcl_preview; if you are not sure which languag…
explain_zplHuman-readable health REPORT for a finished ZPL label, with a 0-100 score: sectioned findings (syntax, size/DPI, orientation, barcodes, fonts, graphics memory, job behaviour); sections that cannot be assessed say so and are excluded from the score. Use it to review or explain a…
convert_zpl_dpiRescale ZPL between printer resolutions (203/300/600 DPI): coordinates, fonts, barcode module width and label size are scaled. Embedded ^GF/~DG image data is NOT scaled; the response says so instead of silently passing it through.
template_listList Labelixa's first-party label template catalog: id, English name, category, size/density and tags. Read-only product content (no tenant data). Fetch one with template_get; render its ZPL with zpl_preview.
template_getFetch one catalog template: metadata, preview image URL and — for non-premium templates — the ZPL source, ready for zpl_preview. Premium templates return metadata for everyone; their ZPL source requires an API key whose plan includes the premium-template feature (same rule as th…
save_labelSave a ZPL label to a Labelixa account so it can be edited, versioned and printed later. With an API key the label is saved immediately and the saved label id is returned. Without a key the label is held for 24 hours and a one-time link is returned: the user opens it, signs in (…
epl_previewRender EPL/EPL2 label code and return a PNG preview. The preview assumes 203 dpi and is an interpretation of the EPL2 manual covering a core command subset — no physical printer validation. `labels` in the response is the TOTAL number of labels the stream prints (a stream may co…
tspl_previewRender TSPL/TSPL2 label code and return a PNG preview. The preview assumes 203 dpi and is an interpretation of the TSPL manual covering a core command subset — no physical printer validation. `labels` in the response is the TOTAL number of labels the stream prints (a stream may…
cpcl_previewRender CPCL label code and return a PNG preview. The preview assumes 203 dpi and is an interpretation of the CPCL manual covering a core command subset — no physical printer validation. `labels` in the response is the TOTAL number of labels the stream prints (a stream may contai…
image_to_zplConvert an image (PNG, JPEG, BMP, GIF or SVG, max 200 KB) to a ZPL ^GF graphic command. SVG is rasterised at the chosen density from its declared size (mm/in honoured); SVGs with external references or a DTD are rejected. Returns the ZPL plus measured dimensions and the physical…
barcode_verifyDecode barcodes from a photo or scan of a PRINTED label (PNG, JPEG, BMP or GIF) and report what a software decoder reads back. Honest by design: 'read' does not guarantee every handheld scanner will read it, and 'not read' does not condemn the label (photo angle/focus matter) —…
zpl_compatibilityCompatibility RISK analysis of ZPL code against a specific printer model, given as manufacturer/model (e.g. 'zebra/zd421'). NOT an emulator and never says 'it works': reports the model's language posture with evidence level and size-rule findings.
bulk_submitSubmit a bulk label production job: one ZPL template with {{variable}} placeholders plus data rows (one object per label). Requires an API key whose plan includes bulk jobs. Quota is charged UPFRONT, one operation per row, and failed rows are not refunded; rows per job are cappe…
bulk_statusStatus of one bulk job you own: state, attempt count and — when finished — the summary with produced count and per-row failures (row number + reason; failed rows never block the rest). Finished outputs stay downloadable for 7 days via the REST endpoint the response names.
bulk_listList your recent bulk jobs (id, state, error class, timestamps), newest first. Useful to recover a lost job id; details via bulk_status.
printer_language_to_zplConvert a SATO SBPL, Honeywell (Datamax) DPL or Honeywell (Intermec) IPL label stream to ZPL, so it can be checked with zpl_validate and rendered with zpl_preview. You must name the source language: language_detect does not recognise these three. Real control characters and the…
printer_listList the printers registered to the Labelixa account (the ones a paired Labelixa DirectPrint agent forwards jobs to). Use a returned device `id` as `device_id` in print_label. Requires an API key whose plan includes printing.
print_labelSend ZPL to a physical printer through the account's Labelixa DirectPrint agent. Requires an API key whose plan includes printing and a printer from printer_list (or a printer group name). The job is QUEUED, not printed: the response says whether the device is mapped by an agent…
print_statusStatus of one print job you own (queued, sent to the agent, delivered or failed) plus when the agent last connected. 'delivered' means the agent handed the bytes to the printer; it does not prove the label came out. `printer_status` is the printer's own status reading taken afte…
