No key · no signup · deterministic

REST API reference

Six endpoints, none of which need a key or an account. Generate a code, build a typed payload, prove a design still scans, decode an image, or run a batch, and when a call is wrong, the error hands back a corrected one you can run as-is.

• GET /v1/qrGenerate a QR codeGET /api/v1/qr turns any string into a QR code image with no key and no signup.›
• GET /v1/{type}Typed endpointsGET /api/v1/{type} builds a correctly formatted payload for you (wifi, upi, vcard, mecard, url, text and the rest) using the exact same builders the web app uses.›
• GET /v1/verifyVerify a design scansGET /api/v1/verify renders the code you describe, rasterizes it, decodes it with a real decoder and compares the result with your input.›
• POST /v1/decodeDecode an imagePOST /api/v1/decode reads a QR code out of an image you send as the request body.›
• POST /v1/qr/batchGenerate up to 1,000 at oncePOST /api/v1/qr/batch takes a shared style and a list of items, each of which may be a raw payload or a typed one, and returns them together.›
• GET /errorsErrors that teachEvery 4xx is RFC 9457 problem+json with an extra fix field containing a corrected, copy-pasteable call.›
