Response
200 · List of events
data?object[]
Show item properties
event_id?string
Stable identifier for the event, formed as <venue>:<venue event ticker> (for example kalshi:KXPRESPARTY-2028). Use it to fetch the event's detail and to group markets by their parent event.
name?string
The event's title as published by its venue, intended for display.
category?string
The event's category, folded into a fixed cross-venue taxonomy (Politics, Elections, Economics, Crypto, Sports and similar, with Other as the catch-all). Every market under the event inherits this value.
region?stringnull
Geographic scope of the event: a two-letter US state code for state-level races, or US for federal ones. Null whenever the event carries no geographic anchor, which covers non-election events and all Polymarket events.
election_date?string,null (date)
The election day this event resolves against, derived from the event's identifier for election markets and null for everything else. The events list is sorted by this field, newest first, with undated events last.
description?stringnull
Longer description of the event as published by its venue. Omitted when the venue supplies none.
created_at?string,null (date-time)
When this event was first recorded by the API. It is a first-seen timestamp on our side, not a venue publication date.
updated_at?string,null (date-time)
When this event's record was last written. The record is rewritten every time the event is re-read from its venue, so this advances even when no field actually changed.
market_count?integer
Total number of markets under this event, counted with no status or filter restriction, so settled and closed markets are included. The public events list reports a market_count covering only the markets that match that request's filters, so the two can legitimately differ for the same event.
meta?object
Show properties
total?integer
Total number of records matching the request across every page, not just the number returned in this one.
page?integer
The 1-based page number this response covers.
per_page?integer
Maximum number of items on a page. The last page may hold fewer.
total_pages?integer
Number of pages available at this per_page. It is at least 1, even when nothing matched.
has_next?boolean
True when a page exists after this one.
has_prev?boolean
True when this is not the first page.
403 · The organization has no paid plan, so the realtime read scopes are refused. Distinct from a 429, which means a plan's budget ran out: nothing here resets on a timer, and the request succeeds only once the organization holds a plan.
error *string
Human-readable reason the request was refused.
status *integer
HTTP status code, repeated in the body.
upgrade_url?string (uri)
Page listing the plans and their request allowances, for buying access. Absent when no plan is available for purchase.
429 · The paid organization's minute or UTC-day request budget is exhausted.
error *"rate_limited"
Always rate_limited. Branch on this to detect a throttled request.
limit *"rpm" | "daily"
Which limit was hit: rpm for the per-minute cap or daily for the daily one.
message *string
Human-readable explanation naming the limit that was exceeded.
upgrade_url?string (uri)
Page listing the plans and their request allowances, for buying a larger budget. Absent when no plan is available for purchase.
