Xpensli Monthly Expense Report Generator

Choose this endpoint when you need a high-level monthly spending summary aggregated across all expense categories. Prefer the annual Schedule C endpoint for tax filing, the CSV export for raw data, the receipt processor for individual transactions, or the natural language query endpoint for ad-hoc questions — this endpoint is best for routine monthly financial reviews.

• No expense data found for the requested month — returns empty or minimal report
• Authentication failure if user credentials or session token are missing or expired
• Invalid month/year parameter resulting in a 400 bad request
• Service unavailable or timeout if backend data aggregation is slow
• Payment not processed (x402 protocol failure), blocking report generation
