The same mode handles heavier analysis. Cursor's self-service volume runs roughly $200M/month through Stripe on interchange-plus (IC+) pricing, which passes through the underlying card-network and issuing-bank costs with a markup. That gives full visibility into the real cost of each transaction, unlike a blended sticker rate like 2.9% + 30c. The analytical advantage comes from the prompt structure, not any one clever question.
- Persona. Open with who's asking and what decision the analysis feeds, so the output lands at the right altitude.
- Data. Point at the tables: the auths history, the balance-transaction file, and per-transaction cost data - card, card type, country, interchange and scheme fees. If the financial warehouse is wired in, Cursor queries it directly instead of needing files.
- Optimization categories. Name the specific levers to investigate - notably L2/L3 data-quality eligibility, where US transactions can qualify for cheaper interchange when you pass the right metadata.
The output is a one-off answer built into a Cursor CanvasA surface that renders visual outputs (such as a coverage or accessibility report) that aren't plain Markdown or diagrams. Press Enter for the full definition., not a tool anyone re-runs. You ask it once, act on the finding, and move on. That is exactly the shape of work that used to require pulling several teams into a room.
"This type of analysis is something that took multiple days and required meeting with many different teams."
