Over deze dienst
I build the plumbing for Kalshi trading bots. I don't sell strategies and I don't promise profit. You bring the logic; I make it run correctly and stop when it should.
Every bot ships with a dry-run flag: it makes every decision and sends nothing, so you watch it trade on paper before a cent moves.
I've run bots against Kalshi's live API for months. Three things that cost me money:
- Your bot can look healthy while placing zero orders. Kalshi retired an order endpoint, and the old one fails silently. No crash, no error, nothing reaches the exchange.
- Your loss breaker can fail OPEN. It runs, it logs, it enforces nothing, because one balance call returns a number where the code expects an object.
- Buying NO is recorded as a sell. Book it wrong and your P&L is wrong from day one.
None of that shows up in a demo. It shows up three weeks in, on your money.
Tell me what you're trying to trade and I'll tell you honestly whether it's buildable. If I think the strategy has a structural problem, I'll say that too.

Veelgestelde vragen
Will the bot be profitable?
That depends on your strategy, and that part is yours. What I control is execution — your rules followed exactly, fees counted correctly, and orders that actually reach the exchange. A sound strategy can still lose money to bad execution, and that's the part I can promise to get right.
Can I see the bot running before I pay?
Every bot ships with dry-run mode on by default. It evaluates markets, decides trades, and logs exactly what it would have sent — without sending anything. You watch it work on live market data before enabling real orders.
Do you need my API keys?
No. I develop against my own credentials and deliver code you configure yourself. You generate your Kalshi keys and paste them in as the final step — I never take custody of them.
Do I need to know how to code?
You should be able to run a Python script on your own machine. Every package ships with a setup guide written for your operating system, and I answer questions while you get it running. Unsure which fits? Message me before ordering.
Can you build any strategy?
If it can be specified, it can be coded. But I'll tell you before you order if I think a strategy has a structural problem. I'd rather lose the sale than build something I know won't behave the way you expect.
Can you build a volume bot, bundler, or wash-trading tool?
No. Not on any platform, and not at any price.
What happens if it stops working months from now?
Two cases. If it's a bug in what I built, I fix it free — whenever you find it, not just inside the support window. If something outside the code changed (Kalshi updates their API, your server is rebuilt, you want different logic), that's a new order, quoted before I start.
How much support is included?
14 days after delivery: questions about installing it, configuring it, and reading its output, answered within one business day, Monday to Friday. Extendable to 30 days as an add-on. After that, bugs in my code I still fix free — new work is a new order, quoted first.
Do you offer ongoing maintenance?
Yes — $45/month covers API changes, dependency updates, and priority response if it stops. Cancel any time. Kalshi has retired an order endpoint with no announcement before, and bots written against the old one kept running, kept logging, and quietly placed nothing.
