    "description": "Verify quotations before you publish them. For any quote, this API answers: is it real, who actually said it, is it cleared to reproduce (public domain vs. in copyright), the correct credit, and a paste-ready citation. Provenance is verified against primary sources and the documented research that traces to them (e.g. Quote Investigator, Wikiquote); where a primary source can't be reached, the quote is marked attributed or disputed rather than asserted. 930 quotes indexed. Use it especially for obscure quotes and for commercial/published use, where getting the attribution or the reuse rights wrong is costly.",
