Kalshi API
CFTC-regulated US event exchange. USD-denominated binary contracts settle at $1.00 (YES wins) or $0.00 (NO wins). REST + WebSocket, RSA-PSS authentication on every request.
For contract semantics and settlement rules, see the kalshi-weather-markets and kalshi-crypto-index-markets skills. For strategy, sizing, and backtesting, see prediction-market-strategy.
VERIFY BEFORE CODING. The Kalshi API has broken backward compatibility before: the host changed (old
trading-api.kalshi.com→ dead), and the order schema changed (integer cents → dollar strings). Always smoke-test signing and order bodies against a live response before shipping.Canonical sources:
- API reference: https://docs.kalshi.com (legacy mirror: https://trading-api.readme.io)
- Official Python starter: https://github.com/Kalshi/kalshi-starter-code-python
Overview
- Base URL:
https://api.elections.kalshi.com/trade-api/v2 - Auth: RSA-PSS on every request — there are no public/unauthenticated endpoints
- No demo parity: the demo environment (
demo-api.kalshi.co) has a near-empty book; use production even for read-only pulls - Contracts: $0.01–$0.99 per contract; pay price if YES wins, lose price if NO wins; max payout = $1.00
Quick Start
1. Credentials
KALSHI_KEY_ID=<your-key-uuid>
KALSHI_PRIVATE_KEY_PATH=~/.kalshi/private.pem
Generate the key in the Kalshi dashboard. Store secrets in environment variables or a secrets manager — never in code.
2. Install
pip install httpx cryptography
3. Host + auth (the part everyone gets wrong)
The host and signature format are where implementations break. Three common failures:
- Using the old
trading-api.kalshi.comhost → 401 - Including the query string in the signed path → 401
- Signing with seconds instead of milliseconds → 401
import os, time, base64, httpx
from cryptography.hazmat.primitives import hashes, serialization
from cryptography.hazmat.primitives.asymmetric import padding
BASE = "https://api.elections.kalshi.com/trade-api/v2"
KEY_ID = os.environ["KALSHI_KEY_ID"]
with open(os.environ["KALSHI_PRIVATE_KEY_PATH"], "rb") as f:
PRIV = serialization.load_pem_private_key(f.read(), password=None)
def _headers(method: str, path: str) -> dict:
"""path must include /trade-api/v2 prefix and exclude query string."""
ts = str(int(time.time() * 1000)) # milliseconds
msg = f"{ts}{method}{path}".encode()
sig = PRIV.sign(
msg,
padding.PSS(mgf=padding.MGF1(hashes.SHA256()),
salt_length=padding.PSS.DIGEST_LENGTH),
hashes.SHA256(),
)
return {
"KALSHI-ACCESS-KEY": KEY_ID,
"KALSHI-ACCESS-TIMESTAMP": ts,
"KALSHI-ACCESS-SIGNATURE": base64.b64encode(sig).decode(),
}
def get(path: str, params=None):
# Sign the path only — query goes into params, not the signature
r = httpx.get(BASE + path, params=params,
headers=_headers("GET", "/trade-api/v2" + path))
r.raise_for_status()
return r.json()
def post(path: str, body: dict):
r = httpx.post(BASE + path, json=body,
headers=_headers("POST", "/trade-api/v2" + path))
r.raise_for_status()
return r.json()
# Example: open markets in a series
markets = get("/markets", params={"series_ticker": "KXHIGHNY", "status": "open"})
Signature spec: RSA-PSS, MGF1 over SHA-256, salt length = PSS.DIGEST_LENGTH. String to sign: {timestamp_ms}{METHOD}{path} where path includes /trade-api/v2 and excludes the query string.
Headers: KALSHI-ACCESS-KEY (UUID), KALSHI-ACCESS-TIMESTAMP (ms), KALSHI-ACCESS-SIGNATURE (base64).
4. Candlestick history
# Returns OHLC for yes_bid / yes_ask + volume + open_interest
# Values are dollar strings: {"close": "0.42"}
candles = get(
f"/series/KXHIGHNY/markets/{ticker}/candlesticks",
params={"start_ts": start_epoch, "end_ts": end_epoch, "period_interval": 60},
)
period_interval is in minutes: 1, 60, or 1440.
YES/NO Order-Book Convention
On Kalshi, yes and no are both resting BID ladders — there is no separate ask book. To take the other side you lift the opposing bid:
no_ask = 1 − best_yes_bid # cost to buy NO right now (lift YES bids)
yes_ask = 1 − best_no_bid # cost to buy YES right now (lift NO bids)
P(YES) mid = (best_yes_bid + (1 − best_no_bid)) / 2
Getting this backwards silently inverts every signal. Use the helpers in scripts/kalshi_orderbook.py.
Orderbook response comes in two variants depending on API tier — normalize before using:
{"orderbook": {"yes": [[price, size], ...], "no": [[price, size], ...]}}
If a price value is > 1.0, it is integer cents — divide by 100.
Order Schema
POST /trade-api/v2/portfolio/orders uses fixed-point dollar STRINGS, not integers. The old schema (integer cents, count, yes_price) returns 400 invalid_parameters.
{
"ticker": "KXHIGHNY-26JUN02-B75.5",
"action": "buy",
"side": "yes",
"count_fp": "1.00",
"yes_price_dollars": "0.01",
"client_order_id": "my-strategy-001",
"time_in_force": "good_till_canceled"
}
Critical field rules — each violation returns 400:
| Field | Rule | Common mistake that 400s |
|---|---|---|
count_fp | fixed-point string "1.00" | integer count: 1 |
{side}_price_dollars | dollar string "0.01" | integer cents yes_price: 1 |
time_in_force | required: good_till_canceled | immediate_or_cancel | fill_or_kill | omitted |
client_order_id | [A-Za-z0-9-] only | . or : in the string — bracket tickers contain ., so never copy the ticker directly |
type | do not send | "type": "limit" |
For the full order lifecycle (amend, decrease, cancel, batch) and strike_type gotchas, see references/auth-and-orders.md.

## Overview
- **Base URL:** `https://api.elections.kalshi.com/trade-api/v2`
- **Auth:** RSA-PSS on every request — there are no public/unauthenticated endpoints
- **No demo parity:** the demo environment (`demo-api.kalshi.co`) has a near-empty book; use production even for read-only pulls
- **Contracts:** $0.01–$0.99 per contract; pay price if YES wins, lose price if NO wins; max payout = $1.00

Generate the key in the Kalshi dashboard. Store secrets in environment variables or a secrets manager — never in code.
### 2. Install
```bash

### 3. Host + auth (the part everyone gets wrong)
The host and signature format are where implementations break. Three common failures:
1. Using the old `trading-api.kalshi.com` host → 401
2. Including the query string in the signed path → 401
3. Signing with seconds instead of milliseconds → 401
```python

return {
"KALSHI-ACCESS-KEY": KEY_ID,
"KALSHI-ACCESS-TIMESTAMP": ts,

}
def get(path: str, params=None):
# Sign the path only — query goes into params, not the signature

r.raise_for_status()
return r.json()
# Example: open markets in a series
markets = get("/markets", params={"series_ticker": "KXHIGHNY", "status": "open"})
```
**Signature spec:** RSA-PSS, MGF1 over SHA-256, salt length = `PSS.DIGEST_LENGTH`. String to sign: `{timestamp_ms}{METHOD}{path}` where path includes `/trade-api/v2` and excludes the query string.
Headers: `KALSHI-ACCESS-KEY` (UUID), `KALSHI-ACCESS-TIMESTAMP` (ms), `KALSHI-ACCESS-SIGNATURE` (base64).
### 4. Candlestick history
```python
# Returns OHLC for yes_bid / yes_ask + volume + open_interest
# Values are dollar strings: {"close": "0.42"}
candles = get(
f"/series/KXHIGHNY/markets/{ticker}/candlesticks",
params={"start_ts": start_epoch, "end_ts": end_epoch, "period_interval": 60},
)
```
`period_interval` is in **minutes**: `1`, `60`, or `1440`.

## YES/NO Order-Book Convention
On Kalshi, **`yes` and `no` are both resting BID ladders** — there is no separate ask book. To take the other side you lift the opposing bid:
```
no_ask = 1 − best_yes_bid # cost to buy NO right now (lift YES bids)
yes_ask = 1 − best_no_bid # cost to buy YES right now (lift NO bids)
P(YES) mid = (best_yes_bid + (1 − best_no_bid)) / 2
```
Getting this backwards silently inverts every signal. Use the helpers in `scripts/kalshi_orderbook.py`.
**Orderbook response** comes in two variants depending on API tier — normalize before using:
```json
{"orderbook": {"yes": [[price, size], ...], "no": [[price, size], ...]}}
```
If a price value is `> 1.0`, it is integer cents — divide by 100.
---
## Order Schema
`POST /trade-api/v2/portfolio/orders` uses **fixed-point dollar STRINGS**, not integers. The old schema (integer cents, `count`, `yes_price`) returns `400 invalid_parameters`.
```json
{
"ticker": "KXHIGHNY-26JUN02-B75.5",
"action": "buy",
"side": "yes",
"count_fp": "1.00",
"yes_price_dollars": "0.01",
"client_order_id": "my-strategy-001",
"time_in_force": "good_till_canceled"
}
```
Critical field rules — each violation returns `400`:
| Field | Rule | Common mistake that 400s |
|---|---|---|
| `count_fp` | fixed-point **string** `"1.00"` | integer `count: 1` |
| `{side}_price_dollars` | dollar **string** `"0.01"` | integer cents `yes_price: 1` |
| `time_in_force` | **required**: `good_till_canceled` \| `immediate_or_cancel` \| `fill_or_kill` | omitted |
| `client_order_id` | `[A-Za-z0-9-]` only | `.` or `:` in the string — bracket tickers contain `.`, so never copy the ticker directly |
| `type` | **do not send** | `"type": "limit"` |
For the full order lifecycle (amend, decrease, cancel, batch) and `strike_type` gotchas, see `references/auth-and-orders.md`.
