One API for everything

Fonts, icons, colors, palettes, image processing, SVG utilities, favicon generation and code tools share one REST API. Rate-limited fair use, no key required to start.

MCP server

Connect Jinero to Claude, Cursor or any MCP client and let the assistant search fonts and icons, recognize a font from an image, remove backgrounds or generate palettes as tools.

Frequently Asked Questions

It exposes Jinero tools to AI assistants through the Model Context Protocol, so an assistant can call them directly from a conversation.
