Try the GDELT Timeline API

Returns how coverage of the required GDELT `query` changes over time, as dated points. `metric` picks `volume` (the default, share of monitored articles), `volume_raw` (matching article count), `tone` (average sentiment), or `lang` and `country` for one series per language or country. Filter with `country`, `language`, `domain`, `timespan` or `from` and `to`; `smooth` runs 0 to 30 (default 0).

Request parameters

Parameter	Type	Required	Prefilled value	Description
query	string	Yes	climate change	GDELT query string. Same syntax as gdelt-search's query.
metric	string	No	volume	Timeline metric. lang and country return one series per language/country instead of one aggregate series.
country	string	No		Convenience source-country filter, appended to the query as sourcecountry:VALUE.
language	string	No		Convenience source-language filter, appended to the query as sourcelang:VALUE.
domain	string	No		Convenience domain filter, appended to the query as domain:VALUE.
timespan	string	No		Relative time window ending now, e.g. 1h, 2d, 1w, 3m. Cannot be combined with from/to.
from	string	No		Start of an absolute time window. Accepts YYYY-MM-DD, RFC3339, or GDELT's raw YYYYMMDDHHMMSS. Cannot be combined with timespan.
to	string	No		End of an absolute time window. Same formats as from.
smooth	integer	No		Moving-window smoothing applied to the timeline, in steps. 0 disables smoothing.

Coverage volume or tone over time for a GDELT query

Response behavior

- `series` contains exactly one entry for `metric=volume`/`volume_raw`/ `tone`; for `metric=lang`/`country` it contains one entry per language/country GDELT found in the matching coverage. Each entry's `points` is chronologically ordered. - `source_url` is the exact upstream GDELT DOC API URL used for the call. - A GDELT-side rate limit or an unrecognized/malformed upstream response surfaces as a `503` upstream error, not a `200` with empty/wrong data.
