Get public index detail

/api/v1/public/indices/{id}GET
Index detail with trailing-return and risk stats, plus composition analytics: state exposure, maturity profile, weight attribution, and per-constituent returns over 1d, 7d, and 30d.
Response
200 ยท Index detail
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). This endpoint accepts either this ticker (case-insensitively) or index_id as its path parameter.
description *stringnull
Free-text description of what the index tracks.
methodology?stringnull
Registered methodology key used to compute the index. Omitted only when no methodology is stored.
methodology_detail?object | null
Methodology-specific public detail, keyed by methodology id. Omitted when empty. methodology stays the id string. An AI Capability Efficiency index sends ace.members, one row per rate that entered the latest published print.
quote_convention?"percent" | "points"
The unit this index quotes trailing performance in. percent: render the change_* fields. points: render the price_change_* fields, because the level is a point sum and a percent of it carries no meaning.
constituents_count *integer
Number of constituents in the index: member markets for a market-basket index, child sub-indices for a composite, bound contracts for a claim-ladder total return (kpi_tr), or rates that entered the latest published print for an AI Capability Efficiency index (ace). 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.
base_index_id?stringnull
For a derived total_return index, the composite index it compounds the returns of; null for the curated families, which have no base. The detail page shows this in place of the constituent count a derived index lacks.
latest_price?numbernull
Most recent index level. Political families use a 50-150 scale (100 is neutral). Team indices (nti, bti) are a NAV level from base 1000. implied_level is the published level from its sleeve prints (Misery is the U-3 + CPI sum). kpi_tr is a total return from a base of 1000. ace is a price return from a base of 1000. See quote_convention and level_interpretation for how this index's methodology frames the level.
level_interpretation?object[]
Methodology-resolved rows explaining what latest_price means, formatted server-side (the curated families frame it as a composite probability, total_return as a compounding return, implied_level in that index's unit). The client renders them verbatim; omitted when the level or the methodology is unavailable.

label *string
value *string
price_change_1d?numbernull
Absolute change in index points (not a percent) from the previous daily close to latest_price. The baseline is the last completed daily close before the current day in US Eastern time, so this is a change against a settled value rather than a rolling 24-hour window.
price_change_7d?numbernull
Absolute change in index points (not a percent) from the daily close seven days before the current day in US Eastern time to latest_price. Null when the index has no daily close that far back.
previous_close_1d?numbernull
The index level at the previous daily close, meaning the last completed daily close before the current day in US Eastern time, not a rolling 24-hour window. Returned by both the public and authenticated index detail routes.
previous_close_7d?numbernull
The index level at the daily close seven days before the current day in US Eastern time, the baseline price_change_7d is measured against. Returned by both the public and authenticated index detail routes.
stats?object | null
Trailing returns and risk statistics computed from the index's daily close series over roughly the trailing 400 days. Returned by both index detail endpoints; the values are null individually when the series is too short for that window.
composition?object | null
Breakdown of the index over its flattened constituents: per-state exposure and a maturity profile of when those constituents expire.
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 human-readable explanation of the halt, composed from the constituent halt counts. Omitted when not halted.
visibility?"public" | "superuser" | "organization"
Access level of the index. public is visible to everyone; organization is visible to members of listed organizations. Other reserved values may appear on authenticated responses. Omitted on the anonymous public tier, which returns only public indices.
official_daily_value?object | null
Most recent official daily value. Null when this index family does not publish daily values.
sleeves?object[]
Current sleeve state for a team index. Empty for other index families.
