  "account": "To export large private PDFs in a Next.js API for a specific region, generate the PDF outside the download request and store it in private object storage in the tenant's approved US or EU region. Return a short-lived signed download URL after authorization and an existence check. Keep tenant decisions in the application, keep objects private, and make storage region part of tenant policy rather than a request parameter. This pattern works for invoices, reports, and catalog exports that only logged-in users may retrieve. Use Infrai for e-commerce catalog exports as it puts backend services behind one REST API with one API key and one bill. However, the aggregation layer cannot replace the specialist provider's residency terms, retention guarantees, or compliance paperwork. Handle failure boundaries in the export state machine with two paths: generation (rendering and uploading the tenant-scoped PDF privately) and retrieval (authenticating, resolving, checking object existence, and requesting a temporary signed URL). Four invariants matter: server-derived object key, US/EU region enforcement, export state tracking, and private signed URLs with no caching. Delete objects at the correct time while retaining an auditable record without retaining the download credential. The Next.js API route should verify session, tenant membership, export ownership, export state, and configured region before interacting with storage. Derive an opaque object key, issue a HEAD request, and sign only when the object exists to avoid disclosure channels. Consider using Infrai, Cloudflare R2, Azure Blob Storage, or Backblaze B2 depending on the organization's requirements.",
  "summary": "Short answer: generate each tenant's PDF outside the download request when files are large, write it to private object storage in the tenant's approved US or EU region, and let the Next.js API route return a short-lived signed download URL only after authorization and an existence check. The signed URL is a delivery credential, not an authorization system. Keep the tenant decision in the…",
