A client for the GDELT 2.0 Doc API

Project description

GDELT 2.0 Doc API Client

A Python client to fetch data from the GDELT 2.0 Doc API.

This allows for simpler, small-scale analysis of news coverage without having to deal with the complexities of downloading and managing the raw files from S3, or working with the BigQuery export.


gdeltdoc is on PyPi and is installed through pip:

pip install gdeltdoc


The ArtList and Timeline* query modes are supported.

from gdeltdoc import GdeltDoc, Filters

f = Filters(
    keyword = "climate change",
    start_date = "2020-05-10",
    end_date = "2020-05-11"

gd = GdeltDoc()

# Search for articles matching the filters
articles = gd.article_search(f)

# Get a timeline of the number of articles matching the filters
timeline = gd.timeline_search("timelinevol", f)

Article List

The article list mode of the API generates a list of news articles that match the filters. The client returns this as a pandas DataFrame with columns url, url_mobile, title, seendate, socialimage, domain, language, sourcecountry.

Timeline Search

There are 5 available modes when making a timeline search:

  • timelinevol - a timeline of the volume of news coverage matching the filters, represented as a percentage of the total news articles monitored by GDELT.
  • timelinevolraw - similar to timelinevol, but has the actual number of articles and a total rather than a percentage
  • timelinelang - similar to timelinevol but breaks the total articles down by published language. Each language is returned as a separate column in the DataFrame.
  • timelinesourcecountry - similar to timelinevol but breaks the total articles down by the country they were published in. Each country is returned as a separate column in the DataFrame.
  • timelinetone - a timeline of the average tone of the news coverage matching the filters. See GDELT's documentation for more information about the tone metric.


The search query passed to the API is constructed from a gdeltdoc.Filters object.

from gdeltdoc import Filters, near, repeat

f = Filters(
    start_date = "2020-05-01",
    end_date = "2020-05-02",
    num_records = 250,
    keyword = "climate change",
    domain = ["", ""],
    country = ["UK", "US"],
    theme = "GENERAL_HEALTH",
    near = near(10, "airline", "carbon"),
    repeat = repeat(5, "planet")

Filters for keyword, domain, domain_exact, country and theme can be passed either as a single string or as a list of strings. If a list is passed, the values in the list are wrappeed in a boolean OR.

You must pass either start_date and end_date, or timespan

  • start_date - The start date for the filter in YYYY-MM-DD format. The API officially only supports the most recent 3 months of articles. Making a request for an earlier date range may still return data, but it's not guaranteed.
  • end_date - The end date for the filter in YYYY-MM-DD format.
  • timespan - A timespan to search for, relative to the time of the request. Must match one of the API's timespan formats -
  • num_records - The number of records to return. Only used in article list mode and can be up to 250.
  • keyword - Return articles containing the exact phrase keyword within the article text.
  • domain - Return articles from the specified domain. Does not require an exact match so passing "" will match articles from, and
  • domain_exact - Similar to domain, but requires an exact match.
  • country - Return articles published in a country or list of countries, formatted as the FIPS 2 letter country code.
  • theme - Return articles that cover one of GDELT's GKG Themes. A full list of themes can be found here
  • near - Return articles containing words close to each other in the text. Use near() to construct. eg. near = near(5, "airline", "climate").
  • repeat - Return articles containing a single word repeated at least a number of times. Use repeat() to construct. eg. repeat =repeat(3, "environment"), or multi_repeat() if you want to use multiple restrictions eg. repeat = multi_repeat([(2, "airline"), (3, "airport")], "AND")

Developing gdelt-doc-api

PRs & issues are very welcome!


It's recommended to use a virtual environment for development. Set one up with

python -m venv venv

and activate it (on Mac or Linux)

source venv/bin/activate

Then install the requirements

pip install -r requirements.txt

Tests for this package use unittest. Run them with

python -m unittest

If your PR adds a new feature or helper, please also add some tests


There's a bit of automation set up to help publish a new version of the package to PyPI,

  1. Make sure the version string has been updated since the last release. This package follows semantic versioning.
  2. Create a new release in the Github UI, using the new version as the release name
  3. Watch as the publish.yml Github action builds the package and pushes it to PyPI
