queryParams.ticker (Required): Market ticker identifier. Use GET /v1/prediction-market/kalshi/markets or GET /v1/search/prediction-market?platform=kalshi&q={keyword} to discover valid tickers. Example: KXBTC2026250-27JAN01-250000.

What this Tool returns
Returns Kalshi price history with outcome-side prices and available OHLC values for the selected window.
Response fields and how to read them
The table follows the official response contract, including nested fields and useful response metadata. [] denotes an array item. Required means required within its parent object, not that a conditional parent always exists. A nullable type permits null; an optional field can be absent. Use the documented conditions below to distinguish missing, empty and zero values. Units and reporting windows apply only where explicitly documented.
Field, type and presence
Meaning and conditions
data.[].high
number; Required within parent; format: double
Highest price as probability (0-1)
data.[].low
number; Required within parent; format: double
Lowest price as probability (0-1)
data.[].open
number; Optional within parent; format: double
Opening price as probability (0-1). Present for daily interval only.
data.[].side_a
object; Required within parent
Yes outcome price data (close price for daily/hourly)
data.[].side_a.label
string; Required within parent
Outcome label: `Yes` or `No`
data.[].side_a.price
number; Required within parent; format: double
Price as probability (0-1)
data.[].side_b
object; Required within parent
No outcome price data (close price for daily/hourly)
data.[].side_b.label
string; Required within parent
Outcome label: `Yes` or `No`
data.[].side_b.price
number; Required within parent; format: double
Price as probability (0-1)
data.[].timestamp
integer; Required within parent; format: int64
Unix timestamp in seconds (midnight UTC for daily, hour start for hourly, trade time for latest)
meta.cached
boolean; Required within parent
Whether this response was served from cache
meta.credits_used
integer; Required within parent; format: int64
Credits deducted for this request
meta.empty_reason
string; Optional within parent
Hint explaining why the data array is empty, when applicable
meta.has_more
boolean; Optional within parent
Whether more items may exist beyond this response. For offset-paged endpoints, continue with a larger offset. For time-series endpoints without offset/cursor controls, true means the requested time range hit an upstream cap; narrow from/to to continue. Omitted when exhaustion cannot be proven.
meta.limit
integer; Required within parent; format: int64
Maximum number of items returned in this response
meta.offset
integer; Required within parent; format: int64
Number of items skipped (pagination offset)
meta.total
integer; Optional within parent; format: int64
Total number of matching items (before pagination). Omitted when total is unknown.
meta.watermark
integer; Optional within parent; format: int64
Warehouse watermark (Unix seconds) this response was computed at, on warehouse-backed endpoints (e.g. Hyperliquid /trades/aggregate) — rows up to this time come from the warehouse, newer rows from the live tail. Omitted elsewhere.
Coverage, units and freshness
Keep the supplier's stated price unit. Historical outcome prices are market observations, not a guaranteed probability of the eventual result.
Inspect any returned observation time, cache status, watermark, pagination and errors using their documented meanings. A successful request alone does not establish complete coverage. Where no freshness or completeness guarantee is documented, treat it as unknown. Saved Examples are historical and viewing them does not refresh data or execute a new call.
Data source and references
Surf supplies this endpoint through its Data API. Response contract and deployed Tool inputs reviewed on 2026-10-03 against official OpenAPI v0.2.102. This is a contract review date, not a data observation time. Coverage depends on the selected endpoint and request.
Use one Toolmu account and a shared prepaid balance across available Tools. Pay per use; no separate supplier subscription is required. The current execution ceiling for this Tool is 0.0288 Toolmu credits per call. This is a maximum, not the settled charge. Before execution, get the current Tool contract and check availability, the latest maximumCredits, your balance and budget. Supplier response credits_used, when present, describes supplier API credits and is not the Toolmu customer charge.
