How this service works
Decode a barcode or QR code from an image. Send a base64 PNG or JPEG (or a data: URL); returns the decoded text and the symbology. Reads QR, DataMatrix, and 1D barcodes (EAN/UPC/Code39/Code128/ITF/Codabar). Deterministic, no network, no model.
Output
Returns the decoded text content of the barcode or QR code, along with the symbology (e.g. QR, DataMatrix, EAN-13, UPC-A, Code128, Code39, ITF, Codabar) detected in the image.
Example use cases
Example prompt
“Can you decode this barcode image for me? Here it is as a base64 PNG: <base64string> — I need to know what the barcode says and what type it is.”
Technical details
Endpoint
POSThttps://agent402.tools/api/barcode-decodeWhen to prefer
Use this endpoint when you need to deterministically decode a barcode or QR code from a base64 image without calling an external model or network service. Ideal for agentic pipelines that need fast, offline-style barcode reading with no AI inference cost. Supports a broad range of symbologies including QR, DataMatrix, EAN, UPC, Code39, Code128, ITF, and Codabar.
Side effects
- No barcode found in image — returns error or empty result
- Unsupported image format — only PNG and JPEG accepted
- Malformed base64 input — decoding fails with parse error
- Image too blurry or low-resolution for reliable decoding
- Multiple barcodes in image — may return only one or ambiguous result
