xpensli.app Export Expenses as CSV

Use this endpoint when you need to bulk-export all expense data in a portable, universally compatible format for spreadsheet analysis, bookkeeping, or import into another system. Prefer this over summary or report endpoints when you want raw, row-level transaction data rather than aggregated totals or formatted reports.

• No expenses on record — returns empty CSV or error indicating no data
• Authentication failure — user not recognized or session invalid
• Service unavailable — 402 payment required if USDC payment not processed
• Rate limiting — too many requests in a short period
• Malformed response — partial CSV if export interrupted
