Presigned URL Upload (any size): Set requestUploadUrl: true to get a presigned PUT URL, then upload directly to object storage. * * Supported Content Types: * - Images: image/png, image/jpeg, image/gif, image/webp, image/svg+xml * - Documents: application/pdf, text/plain, text/markdown, text/html * - Code: text/javascript, application/json, text/css, text/yaml * - Archives: application/zip, application/gzip * - Video: video/mp4, video/webm (use presigned URL for large files) * * Metadata: * Attach any custom metadata for filtering. artifactType is auto-populated from contentType if not provided.
