QR & Barcode Toolkit¶

Create and decode QR codes and barcodes with one API. Generate PNG or SVG output, style QR modules and colors, embed logos, bulk-create up to 20 symbols per request, and decode from either base64 images or remote URLs.

Base URL¶

https://barcode.toolkitapi.io/v1/

Endpoints¶

QR Codes¶

Method	Endpoint	Description
`POST`	`/v1/qr/generate`	Generate a styled QR code as base64 PNG or SVG markup
`GET`	`/v1/qr/generate`	Generate and stream a raw QR image (PNG or SVG)
`POST`	`/v1/qr/decode`	Decode QR codes and barcodes from an image
`POST`	`/v1/qr/bulk`	Bulk-generate up to 20 QR codes

Barcodes¶

Method	Endpoint	Description
`POST`	`/v1/barcode/generate`	Generate a barcode as base64 PNG or SVG markup
`GET`	`/v1/barcode/generate`	Generate and stream a raw barcode image (PNG or SVG)
`POST`	`/v1/barcode/decode`	Decode barcodes and QR codes from an image
`POST`	`/v1/barcode/bulk`	Bulk-generate up to 20 barcodes (PNG)
`GET`	`/v1/barcode/types`	List supported barcode symbologies and constraints

Quick SDK Example¶

from toolkitapi import Barcode

bc = Barcode(api_key="tk_...")

qr = bc.qr_generate(
  data="https://toolkitapi.io/docs",
  format="png",
  size=500,
  module_shape="rounded",
)

ean = bc.generate(
  data="5901234123457",
  barcode_type="ean13",
  format="png",
)

print(qr["format"], ean["barcode_type"])

Python SDK¶

Install and use the dedicated Barcode client:

pip install toolkitapi

from toolkitapi import Barcode

bc = Barcode(api_key="tk_...")
result = bc.types()
print(result["total"])

See drilldowns for endpoint-specific request/response fields and copy-paste examples.

Tip

Use the GET /v1/qr/generate and GET /v1/barcode/generate variants when you want raw bytes directly for image tags, downloads, or file writes, and use the POST variants when you need JSON-wrapped responses.
