Font recognition analyzes a public image URL, detects the largest readable word, and returns ranked open-source font matches. Use font recognition when you want to identify type from screenshots, logos, posters, packaging, and other flattened design references.

​
Request

Send a public http:// or https:// image URL to the font recognition endpoint. The image response must be an image file and no larger than 10 MB. 
curl https://api.mixfont.com/v1/api/lens \
  -H "Content-Type: application/json" \
  -H "x-api-key: $MIXFONT_API_KEY" \
  -d '{
    "image_url": "https://images.example.com/wordmark.png",
    "top_k": 3
  }'
top_k is optional. It defaults to 3 and must be an integer from 1 to 10.

​
Response

The response includes the detected word, its bounding box, the analyzed image dimensions, ranked font matches, and a request id when available.
