What you get#
Onekey exposes GDELT as 3 endpoints behind one API key: 3 endpoints return a list (data is an array). Every answer uses the same envelope (success, data, metadata, error), the cost is reported in metadata.credits_charged, and fields are mapped onto the unified schema so the code you write for GDELT also works for the rest of the news & publishing category.
Endpoints#
| Endpoint | What it does | Parameters | Credits | Status |
|---|---|---|---|---|
articles | News articles matching a query (last 3 months, newest first). | q*, n | 5 | stable |
tone_timeline | Average news tone over time for a query. | q* | 5 | stable |
volume_timeline | Share of news coverage over time for a query (volume intensity). | q* | 5 | stable |
A * marks a required parameter. Each endpoint name links to its reference page with the full parameter table, caching window and a recorded response.
Make a request#
This calls gdelt.articles (5 credits, stable). Replace YOUR_API_KEY with your key; sign up, no card. 1,000 free credits cover the open-platform endpoints. Hard-to-reach platforms (X, TikTok, Instagram, Reddit, and others marked on their page) need a verified email and a purchased pack.
curl "https://api.onekey.dev/v1/gdelt/articles?q=climate&n=5" \
-H "x-api-key: YOUR_API_KEY"Fields you get back#
These unified fields come back from GDELT, with the same names as on every other platform. The count is how many of its 3 mapped endpoints return the field; a field the source lacks is null, never missing. 2 platform-specific fields (ext.<name>) come on top, documented on each endpoint page.
| Field | Type | Endpoints |
|---|---|---|
entity.date | ISO 8601 date | 2 |
author.displayName | string | 1 |
content.createdAt | ISO 8601 date | 1 |
content.language | string | 1 |
content.title | string | 1 |
content.url | URL | 1 |
entity.category | string | 1 |
media.thumbnailUrl | URL | 1 |
The full schema is in Unified schema.
