What it does

Just ask your AI assistant.

"Search for air-quality datasets with a commercial license" "Preview the first 20 rows of that Zenodo dataset" "Find SEC filings mentioning climate risk" "Generate an APA citation for that Hugging Face dataset" "Check if this dataset can be used commercially" "Visualize that dataset"

Mobus fans requests out to every configured platform in parallel, checks licenses, previews data, generates citations, and traces academic lineage — failing gracefully whenever an API key is missing.
