Build a Kalshi trading bot with your AI coding agent.
Super Algo Kit helps you build a Kalshi trading bot or research tool inside your own AI coding agent. Kalshi is reported to be a CFTC-designated exchange for event contracts, with a REST API, WebSocket streams and a demo environment. The kit's default deliverables are tools, such as a calibration tracker. Live trading waits for a confirmed eligibility check for your country and your typed authorize command.

Paper first
A Kalshi bot, built paper first.
Super Algo Kit runs inside the coding agent you already use. It interviews you, writes the spec with pass marks set first, then builds, backtests and paper-tests. Real money starts only when you type the authorize command.
The plan, step by step
Tick them off as you go.
How Kalshi API access and login work
You sign up with identity verification and your country of residence (reported). Your API usage tier starts at Basic and rises by an upgrade request, trading volume or Kalshi's decision (reported). Where the account page issues API keys was not confirmed.
Each request is signed with your private key, so there is no session or daily token to refresh. Demo and production keys are separate and do not cross over (reported). The kit never needs your password or 2FA seed, and the private key stays only where the bot runs.
Who can use Kalshi: eligibility comes first
Kalshi is reported to accept customers in many countries under its Member Agreement, which lists restricted jurisdictions. The kit's prediction-markets pack records the reported list, and India appears in it. The list comes from a search summary, so read the current agreement before relying on it.
In the US, state action against sports event contracts is contested, and state rules change. Super Algo Kit never helps you get around a venue's restrictions. Live trading waits for a confirmed eligibility check for your country, and this page is not legal advice.
Paper trading a Kalshi bot on the demo environment
Kalshi has a demo environment with its own credentials and hosts. How demo differs from production, in liquidity, market list or resets, was not confirmed. Paper results built on demo prices are simulated.
Contracts settle by their written rules and a named source (reported). So the kit saves each contract's rules text with a hash when a strategy is designed and again at trade time.
Kalshi rate limits and costs to plan for
Limits are token buckets (reported). Every signed request costs tokens, 10 by default, and your tier sets the refill rate. A breach returns a rate-limit error with no penalty or cooldown.
The kit reads your account's real budgets at start instead of hard-coding them. It caps itself at 60% of the write budget, a kit judgement. Kalshi's fee schedule was not read, so fees are modelled as clearly marked estimates.
What Super Algo Kit does with Kalshi
Kalshi's API is mid-migration to V2 order calls that use decimal strings for prices and counts (reported). The kit keeps hosts in configuration, parses prices as decimals and pins the SDK version, which is regenerated about weekly. Client order id lookups cover only the last 24 hours (reported), so the kit keeps its own order ledger.
After a timeout, the kit looks the order up before any retry and never resends under a new id. It refuses strategies that rely on non-public information or on influencing an outcome. An independent risk gate caps loss per market and per event, with a kill switch you can run yourself.
Before you rely on it
Gotchas to plan for.
- Use the V2 order calls; the legacy orders path is deprecated (reported).
- Hosts differ across sources, so keep them in configuration, not code.
- Prices and counts are decimal strings; never parse them as floats.
- Contracts can be halted or changed by rule clarifications (reported); re-read the rules before trading.
- The CFTC pursues insider trading and manipulation in event contracts, including mention markets.
