• recognize_font read-only

  Identify which font is used in an image. Powered by our OWN CNN embedding model, trained on the jinero font catalog — it matches fonts by visual shape/style, so it needs NO OCR and NO text (works for Latin and Cyrillic). Send a tight crop of one line of text as either image_url (public URL) or image_base64 (base64/data-URI, e.g. a local screenshot). The image is processed in memory and deleted immediately — never stored. Returns the most visually similar font families with scores. Typically 0.3-1.7 s (an OCR-assisted rerank of top candidates engages when retrieval is uncertain). Rate limit: 5 calls/min per IP (model inference is compute-heavy).

  Parameters:

  • top_k — integer — Number of font matches to return (3–20, default 8).
  • image_url — string — Public URL of an image — a tight crop of one line of text. Provide either this or image_base64. Recognition is by visual shape (no OCR/text needed); Latin & Cyrillic supported.
  • image_base64 — string — Base64-encoded image (raw base64 or a data:image/...;base64 URI), max 8 MB decoded — use this to send a local file/screenshot without hosting it. Provide either this or image_url.

• extract_colors read-only

  Extract a dominant-color palette from an image. Send either a public image_url or image_base64 (base64/data-URI, e.g. a local screenshot). The image is processed in memory and never stored.
