Create one QR code from raw text or a URL. For Wi-Fi, contacts, events, payments and other structured content, use the dedicated typed endpoints so RapidAPI can validate and document every field.

The default response is JSON with a data_uri you can drop straight into an <img>. Set options.format to png, svg, jpeg, webp or pdf to get the image bytes instead. Add style for shapes, gradients, a logo, a frame or a caption; styled codes are decoded before they are returned and the response says verified: true|false with warnings that tell you what to change.

Free tier: data and all options except format: pdf. style and PDF are on PRO and above (a free-tier request that uses them returns 403 plan_excludes_feature and is not billed).

Create one 1D or 2D barcode from data and type. EAN/UPC/ISBN/ISSN take digits and a missing check digit is computed for you. Default output is JSON with a data_uri; set format to png, svg, jpeg, webp or pdf for the bytes.

The module_*, quiet_zone, font_size, text_distance and dpi fields are millimetre settings for 1D print layouts; leave them out for a sensible default. scale, size and border apply to the 2D types (Data Matrix, PDF417, Aztec).

{
  "data": "INV-2026-0042",
  "type": "code128",
  "format": "png"
}

{
  "data": "https://example.com/p/42",
  "type": "datamatrix",
  "format": "svg",
  "size": 400
}

Send one image as image_url (public http(s)) or image_base64 (a data: URI is fine) and get back every QR code and barcode in it: symbology, decoded text, pixel position, orientation, and parsed fields for known content (Wi-Fi, vCard, geo, EPC/SEPA, payment links). Reads QR, Micro QR, Data Matrix, PDF417, Aztec and the common 1D families. Up to 5 MB and 24 megapixels.

{
  "image_url": "https://your-cdn.example.com/ticket.png",
  "formats": [
    "qr"
  ],
  "multiple": false
}

Check a raw QR payload against its published specification before you print or present it. standard is one of gs1-digital-link, epc-sepa, swiss-qr-bill, pix-br-code, upi, emvco-mpm. The response returns valid, the parsed fields, and errors / warnings that name the offending field and cite the spec clause. This is deterministic validation, not scheme certification.

{
  "standard": "upi",
  "payload": "upi://pay?pa=merchant@upi&pn=Cafe%20Ada&am=120.00&cu=INR"
}

{
  "standard": "pix-br-code",
  "payload": "00020126360014BR.GOV.BCB.PIX0114+5511999999999520400005303986540510.005802BR5913Fulano de Tal6008BRASILIA62070503***63041D3D"
}

Validate a payment payload (same standard values as the validator) and, if it is valid, render it as a QR code with the error-correction level and quiet zone the scheme mandates. Invalid payloads return the validation errors instead of an image. Output follows format (json data URI by default, or png/svg/jpeg/webp/pdf).

Known-good and known-bad payloads for every supported standard, each linked to the official source it was taken from. Use them to try the validator, seed tests, or see what a correct payload looks like. Filter with standard.
