generate_barcode

Encode a value into any of 35 barcode and QR symbologies and return the rendered image. Supports QR Code, Data Matrix, PDF417, Aztec, EAN-13, UPC-A, Code 128/39/93, ITF-14 and more. Returns SVG markup by default (or a data: URI when asked), plus a link to the online generator pre-filled with the same value. Use "type" with the canonical name from list_barcode_types; common spellings like "qr" or "code-128" are accepted. Linear formats such as EAN-13 enforce strict charset and length rules and will fail on invalid input.

typestring, required

Barcode symbology, e.g. "Qrcode", "Ean13", "Code128", "Datamatrix", "Pdf417", "gs1-128".

valuestring, required

The data to encode — a URL, product number, tracking code, phone number, Wi-Fi string, etc.

formatstring

Output encoding. "svg" returns XML markup; "data-uri" returns a ready-to-embed data: URL.

heightnumber

Symbol height in pixels (linear formats mainly).

captionstring

Optional human-readable text drawn under the symbol. Defaults to the value itself.

showTextboolean

Draw the human-readable caption under the symbol.

errorCorrectionstring

QR error-correction level. Higher levels survive more damage but produce a denser symbol. Ignored by linear formats.

get_barcode_type

Return the full technical reference for one symbology: character set, data length, check digit rules, X-dimension and quiet-zone guidance, print ratio, magnification, governing standard, inventor and year, typical applications, FAQ, and related formats. Use this to pick a format for a requirement, or to find out why generate_barcode rejected a value.

read-only

Argument	Type	Description
type*	string	Barcode symbology to look up, e.g. "Qrcode", "Ean13", "gs1-128", "pdf417".

list_barcode_types

List every symbology this server can generate (35 formats), grouped by family, with a one-line summary and sample data for each. Call this first when you are unsure which "type" to pass to generate_barcode. Optionally narrow by family (e.g. "EAN / UPC", "2D Barcodes") or category ("linear", "stacked", "2d").

read-only

Argument	Type	Description
family	string	Case-insensitive substring match on the family name, e.g. "Code 128", "2D", "EAN".
category	string	Restrict to one structural class of symbology.
