Kalshi - OpenPX

Setup

Generate an API key id + RSA private key at kalshi.com/account/profile → API Keys. Put them in .env:

KALSHI_API_KEY_ID=...
KALSHI_PRIVATE_KEY_PATH=./kalshi-private-key.pem

Then pass them to the constructor:

import os
from openpx import Exchange

exchange = Exchange("kalshi", {
    "api_key_id":       os.environ["KALSHI_API_KEY_ID"],
    "private_key_path": os.environ["KALSHI_PRIVATE_KEY_PATH"],
})

import { Exchange } from "@openpx/sdk";

const exchange = new Exchange("kalshi", {
    api_key_id:       process.env.KALSHI_API_KEY_ID,
    private_key_path: process.env.KALSHI_PRIVATE_KEY_PATH,
});

use openpx::ExchangeInner;
use serde_json::json;

let exchange = ExchangeInner::new("kalshi", json!({
    "api_key_id": std::env::var("KALSHI_API_KEY_ID").unwrap(),
    "private_key_path": std::env::var("KALSHI_PRIVATE_KEY_PATH").unwrap(),
}))?;
