Manage & analytics

GET    /api/manage/{token}            # link details + totals
PUT    /api/manage/{token}            # update target/payload/utm/active/title
DELETE /api/manage/{token}            # delete link + analytics
GET    /api/manage/{token}/stats?days=30
GET    /api/manage/{token}/scans.csv  # raw scan export

/stats returns totals, unique visitors, a per-day series and top-10 breakdowns for device, OS, browser, country, city, referrer and QR-vs-link source.

Bulk creation

POST /api/bulk            # JSON array of link objects, or {"csv": "alias,target,title,campaign\n..."}
POST /api/bulk?format=csv  # same, responds with a CSV of created codes

Max 500 rows per request.

QR images

GET /api/qr?data=hello&size=1024&fg=%23000000&bg=%23ffffff&format=png|svg&ecl=M
GET /{code}/qr.png   GET /{code}/qr.svg    # QR for an existing short code

Custom domains

POST /api/domains  {"domain": "qr.yourbrand.com"}

Then point a CNAME for that hostname at snapqr.link. TLS certificates are issued automatically on first visit, and your short codes resolve on your own domain.

Limits

Fair-use rate limits apply per IP (60 links/hour, 10 bulk requests/hour, 300 QR images/hour). Destinations must be public http(s) URLs. Codes serving malware or phishing are removed.

Example: curl

curl -X POST https://snapqr.link/api/links \
  -H "Content-Type: application/json" \
  -d '{"kind":"url","target":"https://example.com","alias":"demo-123"}'
