convert_statement
Upload a bank statement (PDF, CSV, XLS, XLSX, or OFX) as base64 and run AI extraction + categorisation. Returns a session_id plus access.level: "full" when an API key with credit was supplied, otherwise "preview" (5 sample rows, other rows masked) with an unlock_url a human can open to buy the full file for $9.99. Large statements can take 1-3 minutes; if status is "processing", poll get_job.
