## AI Search supports extensionless R2 objects with Content-Type metadata

AI Search can index R2 objects without filename extensions when they include supported `Content-Type` metadata. This supports object keys that do not include file extensions while preserving file-type validation during indexing.

For supported file types and Content-Type requirements, refer to [R2 data sources](https://developers.cloudflare.com/ai-search/configuration/data-source/r2/).
