GraphQL AccessALPHA
Access QR Code Generator through GraphQL to combine it with other API calls in a single request. Query only the qr code generator data you need with precise field selection, and orchestrate complex data fetching workflows.
Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.
POST https://api.apiverve.com/v1/graphqlquery {
qrcodegenerator(
input: {
value: "https://apiverve.com"
type: "url"
format: "png"
margin: "0"
}
) {

}
}Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.
CORS Support
The QR Code Generator API accepts cross-origin requests from any origin, so it can be called directly from browser-based applications without a proxy. See CORS support →
Rate Limiting
QR Code Generator requests are throttled per minute on the Free plan and unthrottled on paid plans. Exceeding the limit returns 429 Too Many Requests; rate-limit usage is reported in the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers. See per-plan limits and best practices →
Error Codes
The QR Code Generator API uses standard HTTP status codes — 200 on success, 400 for invalid parameters, 401 for missing or invalid keys, 403 for insufficient credits, 429 for rate-limit exhaustion, and 500/503 for server-side issues. Each error response includes an X-Request-ID header you can quote when contacting support. See full error handling guide →
SDKs for QR Code Generator
Official QR Code Generator packages on npm, PyPI, NuGet, and JitPack — plus a Postman collection and an OpenAPI spec. See the SDK guide →
No-Code Integrations
QR Code Generator works with Zapier, Make, Pipedream, n8n, and Power Automate using the same API key. See setup guides →
Frequently Asked Questions
How do I get an API key for QR Code Generator?
How many credits does QR Code Generator cost?
Each successful QR Code Generator API call consumes credits based on plan tier. Check the pricing section above for the exact credit cost. Failed requests and errors don't consume credits, so you only pay for successful qr code generator lookups.
Can I use QR Code Generator in production?
The free plan is for testing and development only. For production use of QR Code Generator, upgrade to a paid plan (Starter, Pro, or Mega) which includes commercial use rights, no attribution requirements, and guaranteed uptime SLAs. All paid plans are production-ready.
Can I use QR Code Generator from a browser?
What happens if I exceed my QR Code Generator credit limit?
When you reach your monthly credit limit, QR Code Generator API requests will return an error until you upgrade your plan or wait for the next billing cycle. You'll receive notifications at 80% and 95% usage to give you time to upgrade if needed.
