Why developers choose QR Nova

The Stripe of QR codes

Most QR code APIs are an afterthought — bolted onto a dashboard product, poorly documented, with opaque rate limits. QR Nova's API was built API-first with Stripe-quality conventions: consistent error envelopes, scoped authentication, and a machine-readable OpenAPI spec that AI agents can consume directly.

Unlimited API calls on every paid plan — no monthly quotas
Scoped API keys (qr:read, qr:write, analytics:read, export:read)
Stripe-style error responses with request_id and param fields
OpenAPI 3.1 spec at /api/v1/openapi.json
Interactive documentation with "Try it" requests
SHA-256 hashed keys — never stored in plaintext
CORS enabled — works from any origin
Burst rate limiting only — no artificial call caps

Developer FAQ

How much does API access cost?

API access is included on every paid plan (Starter $9/mo and up). There are no per-call charges or monthly quotas — unlimited requests on all paid plans.

What authentication does the API use?

Bearer token authentication. Create API keys in your dashboard with specific scopes. Keys are prefixed with qrn_ and hashed with SHA-256 at rest.

Is there rate limiting?

Only burst rate limiting to protect infrastructure (per-minute via Cloudflare). There are no monthly call quotas. If you hit a burst limit, the response includes a Retry-After header.

Can AI agents use the API?

Yes. The OpenAPI 3.1 spec at /api/v1/openapi.json includes plan matrices, scope mappings, and response schemas that AI agents (Claude, GPT, etc.) can parse for autonomous operation.

Is there an SDK?

A TypeScript SDK is on the roadmap. For now, the OpenAPI spec can generate typed clients via tools like openapi-typescript.
