How this service works
Get full detail for a single Kalshi event with all its nested markets. Mutually-exclusive flag tells you whether the markets partition outcome space (e.g. one winner). Useful for: viewing all candidates in an election, all CPI ranges, all weather buckets.
Output
Returns full event metadata for the specified Kalshi event, including all nested market objects (each with their own ticker, title, and outcome details), plus a mutually-exclusive flag indicating whether the markets together partition the full outcome space (e.g. exactly one can resolve YES).
Example use cases
Example prompt
“Pull all the markets nested under the Kalshi event with ticker PRES-24 and tell me whether the outcomes are mutually exclusive — I want to see every candidate or outcome bucket listed.”
Technical details
Endpoint
POSThttps://agent402.tools/api/kalshi-eventWhen to prefer
Use this endpoint when you need a complete picture of a Kalshi event — all its child markets, their titles, and whether they are mutually exclusive — rather than just a list of top-level events. Ideal for election markets (all candidates), economic indicator markets (all CPI ranges), or any event where understanding the full outcome space matters.
Side effects
- Unknown or invalid eventTicker returns a 404 or error response
- Event ticker exists but has no nested markets (empty markets array)
- Kalshi API unavailable upstream causing a 502 or timeout
- Malformed request body (missing eventTicker field) returns a 400 validation error
- Payment not settled via x402 results in a 402 payment required error
