How this service works

imagepeek (Tanod) QR and barcode reader: decoded text, type and position of every code in an image. Use when an image holds QR codes or barcodes whose decoded text, positions or payment fields are needed.

Output

Returns an array of decoded codes found in the image, each with the raw decoded text, code type (QR/barcode variant), bounding box coordinates, and corner points. For EMVCo payment QRs, also returns fully parsed fields: payment scheme (PIX, PromptPay, SGQR, etc.), merchant name and city, currency, amount, CRC validity, merchant account information, and any warnings. Also includes image metadata (format, dimensions, file size, animated) and the library attribution.

Example use cases

Validate a PIX payment QR before sending

“I need to verify this PIX QR code before my customer scans it — can you decode it from this URL and check that the CRC is valid, and tell me the merchant name and amount? https://mystore.com/checkout-qr.png”

Extract URL or text from product QR code

“Read the QR code in this base64 image for me and tell me what text or URL it encodes — here's the image data: data:image/png;base64,iVBORw0KGgo...”

Parse PromptPay QR for accounting records

“I have a PromptPay QR code image at https://payments.example.com/promptpay-receipt.png — can you decode it and pull out the payment amount, currency, and merchant details for my records?”

Endpoint

POSThttps://tanod.dev/v1/image/qr-read?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need to decode QR codes or barcodes from images programmatically, especially when you also need EMVCo/payment QR parsing (PIX, PromptPay, SGQR, DuitNow, QR Ph) with CRC validation and structured merchant data — capabilities rarely bundled together in generic OCR APIs. It requires no signup and charges only $0.002 per call, making it cost-effective for occasional or automated use.

Side effects

Image URL is private, internal, or IP-literal host — refused with error
Image exceeds 10 MB — rejected
No QR or barcode found in image — returns empty codes array
Malformed base64 input — decode error
Image format not supported — error response
QR text is not valid EMVCo TLV — emv field may show valid_tlv: false with warnings
Network timeout fetching remote image URL

Input

Schema · Request body

Field	Type	Description
url	—	Public http(s) URL of the image (at most 10 MB; private, internal and IP-literal hosts are refused); or use image_base64.
parse_emv	boolean	Also return `emv`, the parsed fields and CRC check, for a QR whose text is an EMVCo payment payload (starts 000201: PIX, QR Ph, SGQR, PromptPay, DuitNow, ...). Default true.
image_base64	—	The image as standard or url-safe base64 (at most 10 MB decoded; a data:image/...;base64, prefix is fine); or use url.
