}Forecast history for a market
The market-implied probability of the YES outcome over time — the curve behind a market’s forecast chart.
Built from executed trade prices, bucketed and averaged. A market that
has quotes but no trades yields an empty series, so an empty
forecast_history means “nothing traded in this window”, not “no such
market”. Unknown market ids also return 200 with an empty array; only a
non-numeric or non-positive id is rejected.
This is the market’s own price. For the underlying instrument a market
resolves against, use GET /price-history.
Bucket width follows range
You choose a window, not a resolution — period_interval on each point
reports the width you actually got, in minutes:
range | Window | Bucket width |
|---|---|---|
1d | last day | 1 minute |
1w | last week | 60 minutes |
1m | last month | 60 minutes |
all | full history | 1440 minutes (1 day) |
At most 2000 points are returned. start_ts / end_ts narrow the
window within the chosen range but do not change the bucket width.
Timestamp units
start_ts, end_ts and end_period_ts are all in seconds here — unlike
GET /price-history, whose response is in milliseconds. Buckets are
identified by their end, not their start.
No authentication
Forecast data is public. No bearer token is required.

}Path Parameters
The tradable market id (outcomes[].id from GET /events/details), not an event id. Must be a positive integer.
x >= 1Query Parameters
Window to return, which also fixes the bucket width.
1d, 1w, 1m, all Optional lower bound as unix seconds. Narrows the window within range; does not change bucket width.
x >= 0Optional upper bound as unix seconds.
x >= 0Response
Forecast points, oldest first. Empty when nothing traded in the window.
