Can I export a excalidraw in obsidian to .excalidraw file out of obsidian?

Hi, thanks for this wonderful plugin.
But I have some questions

I'm writing a plugin for my blog to render a obsidian vault online, and I'm try to deal with the excalidraw file.
I know that I can export it to the official ".excalidraw" file, and I can download excalidraw lib to render it.
But to export it, it seems I have to open the Obsidian, but I hope that I can export it without obsidian.
From my knowledge, the plugin export only a file don't need other file or Image, they can be transformed to the link correctly.
So, are there any api that I can use to export it by javascript( I can download a lib by npm and import it to use) (?

Please tell me if this API exists, thank you!
I'm sorry if I asked a repetitive question
