category

Optional

Return only markets in this category. The exchange indexes its series by category, so the actor asks it for that category's series and fetches only those — it does not scan the whole feed and discard the rest. Typing a close variant works too ("weather" finds Climate and Weather); an unrecognised one stops the run and lists the valid names rather than returning nothing.

Default:

Options:

SportsEntertainmentPoliticsElectionsFinancialsEconomicsMentionsClimate and WeatherScience and TechnologyCryptoCompaniesWorldHealthCommoditiesSocialTransportationExoticsAIEducation

📊 Market status

status

Optional

Which markets to return. Was previously fixed to "open", which put closed and settled markets — the whole historical and settlement use case — out of reach.

Type:string

Default:open

Options:

openclosedsettledunopenedany

🧹 Exclude auto-generated combination markets

excludeMultivariate

Optional

Kalshi auto-generates enormous numbers of multi-leg parlay markets (KXMVECROSSCATEGORY…). Measured on the live feed they are 98.6% of all open markets and almost none of them trade. On by default so a run returns markets a person recognises.

Type:boolean

Default:true

📈 Min 24h volume

minVolume24h

Optional

Drop markets that traded fewer than this many contracts in the last 24h. Use 1 to keep only markets that traded at all today.

Type:integer

Minimum:0

📊 Min lifetime volume

minVolume

Optional

Drop markets with less total volume than this.

Type:integer

Minimum:0

🔓 Min open interest

minOpenInterest

Optional

Outstanding contracts. A better liveness signal than volume — it says money is still at risk, not merely that a trade once happened.

Type:integer

Minimum:0

💧 Min liquidity (USD)

minLiquidity

Optional

Resting order-book depth in dollars. Note: the open-markets feed reports 0 here for most markets, so a non-zero value filters hard.

Type:integer

Minimum:0

💯 Max Results

maxResults

Optional

Maximum number of markets to return. The exchange carries about 103,000 tradable markets and 0 returns all of them, which is a long run — a measured run delivered 30,000 in 55 minutes, and how long a full sweep takes varies a great deal from run to run. Most of the exchange is auto-generated combination markets, which are excluded by default, so narrowing by Category or Series Ticker is what makes a large run quick.

Type:integer

Minimum:0

Maximum:200000

Default:200

📖 Include order book

includeOrderBook

Optional

Resting bids on both sides, with best price and total depth. COSTS ONE EXTRA REQUEST PER MARKET returned — a 1,000-row run is 1,000 extra requests.

Type:boolean

Default:false

📖 Order book depth

orderBookDepth

Optional

Price levels per side. Only used when the order book is on.

Type:integer

Minimum:1

Maximum:100

Default:10

🧾 Include recent trades

includeTrades

Optional

The public trade tape for each market: time, side, size, price, and whether it was a block trade. No trader identity exists in this data — Kalshi publishes none. COSTS ONE EXTRA REQUEST PER MARKET.

Type:boolean

Default:false

🧾 Trades per market

tradesLimit

Optional

Newest trades to keep per market. Only used when trades are on.

Type:integer

Minimum:1

Maximum:200

Default:20

📈 Include price history (candles)

includeCandles

Optional

OHLC candles with open interest and volume per period. COSTS ONE EXTRA REQUEST PER MARKET.

Type:boolean

Default:false

📈 Candle lookback (hours)

candleLookbackHours

Optional

How far back to fetch OHLC candles, in hours. Long windows at fine periods are split into several requests per market and fetched in sequence, so they work but they take time: 24 hours of hourly candles is one request, while 90 days of 1-minute candles is 26 requests and about 5 seconds for a single market.

Type:integer

Minimum:1

Maximum:2160

Default:24

📈 Candle period (minutes)

candlePeriodMinutes

Optional

Candle size. The exchange supports exactly three: 1 minute, 1 hour and 1 day — anything else is rejected outright. Finer candles over a long lookback mean more requests per market; see Candle Lookback Hours.

Type:string

Default:60

Options:

1601440

🔗 Paste / Direct URLs

startUrls

Optional

One or more direct search or listing detail URLs to process. When set, other search filters are ignored.

Type:boolean

Default:false

♻️ Incremental Mode

incrementalMode

Optional

Compare against the previous run and report what is new, what moved, and what closed. stateKey is optional — it defaults to a value derived from the series you are tracking, so different series never share state.

Type:boolean

Send results to a connected app

Type:string

🔄 Emit Unchanged Listings

emitUnchanged

Optional

When incremental mode is on, also emit listings whose content has not changed since the last run. Markets that vanish from the exchange are marked inactive in state but are not emitted as rows.

Type:boolean

Default:false

⚰️ Emit Expired Markets

emitExpired

Optional

Also return a row for markets that were in a previous run but are gone now. The row carries the market ticker, when it disappeared and your state key — not a price, because the market is no longer there to have one. Requires Incremental Mode and a run that saw the whole set.

Type:boolean

Default:false

🚫 Skip Reposts

skipReposts

Optional

In incremental mode, skip listings that appear to be reposts of a previously-seen expired listing with matching details.

Type:boolean

Default:false
