How this service works
Generate a QR code (PNG base64) from text/URL/WiFi/vCard with size and error-correction control.
Output
Returns a PNG image of the QR code encoded as a base64 string, ready to embed directly in an img src tag or save as a file. The image size and error-correction level reflect the parameters provided.
Example use cases
Restaurant menu QR for table cards
“Create a QR code for https://tacos-el-rancho.com/menu at 300px size with medium error correction — I'll print it on laminated table cards.”
WiFi guest network sharing
“Generate a QR code that lets guests join my WiFi — network name is GuestNet, password is sunshine42, it's WPA2, make it 350px with high error correction.”
Business card vCard QR code
“Make a QR code encoding my vCard contact info — name Jane Doe, email jane@acme.com, phone +1-555-0199, company Acme Corp — at 400px with the highest error correction level.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/qr-generateWhen to prefer
Choose this endpoint when you need to programmatically generate QR codes from arbitrary text, URLs, WiFi credentials, or vCard contact data and receive a ready-to-use PNG base64 image. It is particularly well-suited for agents that need to embed QR codes in generated documents, emails, web pages, or printed materials. Prefer it over client-side QR libraries when you need a server-side, stateless, pay-per-use solution with no library dependencies.
Side effects
- Invalid or empty input text returns a 400 error
- Unsupported data type (e.g. malformed vCard) may produce an unreadable QR
- Extremely long input strings may exceed QR code capacity limits
- Invalid size values (negative or zero) return a validation error
- Unknown error-correction level value returns a 400 bad request
