Unfortunately, I couldn't find any information on a specific "Vectors API" in my search results. However, I did find an @expo/vector-icons package that provides built-in support for popular icon fonts and the tooling to create your own Icon components from your font and glyph map.

If you're looking for a Java client to interact with the Vectors API, you can try searching for "Vectors API Java client" or "Vectors API jar download".

Here is an example of how you might use the @expo/vector-icons package in Java:

import com.expo.ioicons.RNVectorIcons;

// Load the icon font
RNVectorIcons.loadFont("path/to/font.ttf");

// Use the icon component
RNVectorIcons.Icon name="plus" size={24} color="#333"} />

Note that this is just an example, and you will need to modify it to fit your specific use case.
