Kalshi API Keys

Connect your Kalshi account to trade CFTC-regulated event contracts. Kalshi uses RSA key-pair authentication — you'll generate a private key and register the public key on kalshi.com.

US-Only Exchange

Kalshi is a CFTC-regulated Designated Contract Market available to US residents only. No VPN or special routing is needed — all Kalshi bots run on the default engine instance.

Markets cover politics, economics, weather, finance, tech & AI, and culture.

Step 1: Generate RSA Key Pair

Kalshi uses RSA-PSS signing instead of simple API key + secret. You generate a private key locally and upload the public key to Kalshi.

  1. 1
    Open a terminal and generate an RSA-4096 key pair: 
    openssl genrsa -out kalshi_private_key.pem 4096
openssl rsa -in kalshi_private_key.pem -pubout -out kalshi_public_key.pem
  2. 2 Keep kalshi_private_key.pem private — you'll paste its contents into TraderBotz

Step 2: Register API Key on Kalshi

  1. 1 Log in to kalshi.com and go to Settings → API Keys
  2. 2 Click Create API Key
  3. 3 Upload your kalshi_public_key.pem file
  4. 4 Copy the API Key ID that Kalshi generates

Step 3: Add to TraderBotz

  1. 1 Go to Accounts in the sidebar
  2. 2 Click Add Account and select Kalshi
  3. 3 Enter a name, paste the API Key ID from Kalshi
  4. 4 Paste the entire contents of kalshi_private_key.pem into the Secret field
  5. 5 Click Test Connection and save

Security: Your RSA private key is stored encrypted at rest in TraderBotz. It is only used server-side to sign API requests to Kalshi — it is never exposed to the frontend.

Demo environment: Kalshi provides a demo API at demo-api.kalshi.co for testing with paper money. We currently default to the production API — contact us if you'd like to use the demo env.
