name?string

Full display name of the reference rate.

description?stringnull

Free-text description of the rate. Omitted for rates created without one.

methodology?string

How the rate blends its source market prices into a single value: volume_weighted_average, simple_average, or median.

sources?object[]

market_id?string

display_ticker?string

weight?number

latest_price?numbernull

question?stringnull

end_date?string,null (date-time)

is_active?booleannull

latest_price?numbernull

Most recent rate value on the 0-100 scale, where 52.4 means 52.4 percent. Omitted when the rate has no computed value yet.

spread?numbernull

Dispersion across the rate's source markets at the latest computed value: the highest source price minus the lowest, in points on the 0-100 scale. This is a measure of source disagreement, not a bid/ask spread.

price_change_1d?numbernull

Absolute change in points on the 0-100 scale (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, not a rolling 24-hour window.

price_change_7d?numbernull

Absolute change in points on the 0-100 scale (not a percent) from the daily close seven days before the current day in US Eastern time to latest_price. Null when the rate has no daily close that far back.

previous_close_1d?numbernull

The rate value 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 GET /api/v1/public/rates/{id}; omitted on GET /api/v1/rates/{id}.

previous_close_7d?numbernull

The rate value at the daily close seven days before the current day in US Eastern time, the baseline price_change_7d is measured against. Returned by GET /api/v1/public/rates/{id}; omitted on GET /api/v1/rates/{id}.

stats?object | null

Trailing returns and risk statistics computed from the rate's daily close series over roughly the trailing 400 days. Returned by GET /api/v1/public/rates/{id} only; always omitted on GET /api/v1/rates/{id}.

404 · Rate not found

error?string

Stable, machine-readable code identifying the failure; branch on this rather than on message. One of bad_request, unauthorized, forbidden, not_found, conflict, service_unavailable, upstream_error, service_error, or internal_error.

message?string

Human-readable explanation, safe to show to a user. For client errors it names the specific problem; for server-side failures it is a generic notice and the underlying detail is deliberately withheld.
