iOS Obsidian Vault Database Access or API

I want to access Obsidian notes and tags on iOS for a personal project on iOS. The Obsidian vault is stored in iCloud. I know how to access the .md files and I can parse the data from it.

However I want to know if there is any way to access the underlying database that Obsidian maintains for a vault, so that I don’t have to rebuild the database and look for changes every time in my application ?
