Nothing stored, fair-use limits. Your file lives only in memory for the length of this request, never written to disk. Limits: 200 KB for pasted or uploaded XML, 10 MB for PDF uploads, fair-use rate limits per visitor — plenty for testing real invoices, not built for bulk batches (the paid API has no such cap).
