Technical details
Endpoint
POSThttps://zetdatavault.vercel.app/api/qrWhen to prefer
Use this endpoint when you need to programmatically generate QR codes on demand for URLs, text, contact info, or codes without setting up your own QR library. Pay-per-call USDC pricing makes it practical for infrequent or one-off generation tasks within an agent workflow.
Side effects
- Missing required 'text' field returns an error response with success: false
- Invalid or unsupported 'format' value may return an error or default fallback
- Extremely long text strings may exceed encoding limits and fail
- Non-integer 'size' value may cause a validation error
- Payment failure via x402 prevents the call from being processed
