Response
200 · List of indices
data?object[]
Show item properties
index_id *string
Stable identifier for the index (for example red). Use it as the {id} path parameter on the index detail, constituents, and price endpoints.
name *string
Full display name of the index.
ticker *string
Short uppercase symbol for the index (for example RED). The detail endpoint accepts either this ticker (case-insensitively) or index_id as its path parameter.
description *string
One-line description of what the index tracks, suitable for a listing card.
constituents_count *integer
Number of constituents in the index: member markets for a market-basket index, or child sub-indices for a composite. A derived index that inherits its book from a base index reports 0 and names that base in base_index_id.
is_composite *boolean
True for a composite index (its constituents are other indices and its price blends child sub-index values); false for a market-basket index (its constituents are exchange markets). Always present, so a client can branch on index kind even when the index has no constituents yet.
office_category *stringnull
The index's declared office category (lowercase, e.g. "senate"), the input to methodology weighting and composite child-weight derivation. Null for composites and uncategorized indices; always present.
latest_price?numbernull
Most recent index level, on the base-100 index scale (100 is neutral; for the probability-based families each point above or below 100 is one percentage point of the blended win probability). Omitted when the index has no computed value yet.
previous_close_1d?numbernull
The index level at the previous daily close, meaning the most recent completed daily close before the current day in US Eastern time, not a rolling 24-hour window.
change_7d?numbernull
Trailing percent change from the index value 7 days ago to the live tip, computed server-side from the daily aggregate. Powers the indices listing's 7D timeframe toggle. Omitted when there is no daily close that far back.
change_30d?numbernull
Trailing percent change over the last 30 days. Omitted when there is no daily close that far back.
change_90d?numbernull
Trailing percent change over the last 90 days. Omitted when there is no daily close that far back.
previous_close_7d?numbernull
The index value (daily close) 7 days before the snapshot — the baseline change_7d is measured against, so a client can show the absolute change on the same baseline. Omitted when there is no daily close that far back.
previous_close_30d?numbernull
The index value (daily close) 30 days before the snapshot.
previous_close_90d?numbernull
The index value (daily close) 90 days before the snapshot.
updated_at?string,null (date-time)
Timestamp of latest_price. Omitted when the index has no computed value yet.
methodology?stringnull
Key of the methodology family that defines this index's constituent weighting and level calculation, for example upfi, battleground, or total_return. Null for an index with no methodology recorded.
base_index_id?stringnull
For a total_return index, the composite index it derives its book from; null for every curated family.
created_at?string (date-time)
When the index was created in this API. Returned by the authenticated indices list only.
display_order?integernull
Presentation ordering; lower values sort first, null sorts last.
halted?boolean
True when the latest index value was carried forward because the index fell below its constituent floor.
halt_valid_constituents?integernull
When halted, the valid (priced, guardrail-passing) constituents at the most recent halt cycle. Omitted when not halted.
halt_min_constituents?integernull
When halted, the category constituent floor the index fell below. Omitted when not halted.
halt_reason?stringnull
When halted, a render-ready human-readable explanation of the halt, composed from the counts above. Omitted when not halted.
party_side?"republican" | "democrat"
Which party line the basket is priced on, or null for a non-party index. Drives composition.state_exposure.party_lean (the Dem/Rep axis the state map colors on). Always present so a client can render the side an index carries rather than inferring it.
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.
