data?object[]
Show item properties
timestamp?string (date-time)
Start of the aggregation bucket this point covers, in UTC. Daily buckets are anchored to midnight US Eastern, so a 1d point's timestamp is 04:00 or 05:00 UTC depending on daylight saving.
price?number
Value of the series for this bucket: the last price recorded within it. Equals ohlc.close on the same point where OHLC is returned, and is the same statistic the previous_close_* baselines are measured against. Markets and rates are 0-100. Political indices (UPFI and related families) are roughly 50-150. NTI team indices and NTI composites are a NAV level from base 1000 (quote_convention is points).
price_raw?numbernull
Not currently reachable on any tier, and always absent. The unsmoothed value exists only on the un-bucketed series, but every accepted interval (and the default) maps to a bucketed one, so no request can return it.
volume?numbernull
Not currently populated on any price series, on any tier, and always absent. Reserved: use the market volume fields for traded volume.
ohlc?object | null
Open, high, low and close for the bucket, on the same 0-100 scale as price. Returned on the market and rate price series only (index series omit it), and on a daily series a gap-filled day repeats the previous day's values rather than reporting new trading.
spread?numbernull
Dispersion across the source markets behind a reference-rate value: the highest source price minus the lowest, in the same 0-100 points as price. Meaningful only on rate series, and currently not populated on any price-series response, so it is always absent.
sources?objectnull
Provenance for a reference-rate value: the blending method used, plus the per-source prices and weights behind it. Currently not populated on any price-series response, so it is always absent; use constituents for the per-source breakdown.
constituents?arraynull
The source markets behind a reference-rate value at this timestamp, each with its probability (0-100) and its weight renormalized to sum to 1 across the markets listed. Returned on the authenticated rate price series only, covering markets that were active at the timestamp and traded in that bucket; pass sources=false to omit it.
meta?object
Show properties
total?integernull
Total number of records matching the request across every page, not just the current one. null on an uncounted list; page using has_next. A relevance-ranked search is uncounted, and a searched events list stays uncounted even with sort. A searched markets list with sort returns a total over the ranked matches (at most 10,000).
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?integernull
Total number of pages available at the current per_page. null whenever total is null; page using has_next.
has_next?boolean
True when a page exists after this one.
has_prev?boolean
True when this is not the first page.
total_capped?boolean
True when total and total_pages reflect the server's counting ceiling rather than the exact matched count: the real set is at least total large. Render such totals as a lower bound (for example "10,000+"). Omitted when the count is exact. A sorted markets search that fills the 10,000-candidate ceiling sets this flag.
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.
404 · Market 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.
429 · The organization's minute or UTC-day request budget is exhausted, or the organization has reached its cap on requests running at the same time (`limit: "concurrency"`). Wait `Retry-After` seconds before retrying; for a concurrency 429, reduce parallelism.
error *"rate_limited"
Always rate_limited. Branch on this to detect a throttled request.
limit *"rpm" | "daily" | "concurrency"
Which limit was hit: rpm for the per-minute cap, daily for the daily one, or concurrency for the cap on requests running at the same time.
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.
