GDELT Project vs Guardian Open Platform: overview
GDELT Project
The GDELT Project, created by Kalev Leetaru, watches broadcast, print and web news in more than 65 languages and publishes fresh data every 15 minutes. The DOC 2.0 API needs no key and no signup, which makes it the fastest free start here, and it returns article lists and timelines for a query. Bulk event and knowledge-graph tables are also available in Google BigQuery for SQL users. Two things trip developers up. Responses contain metadata and links only, so you have to fetch and parse each article yourself, and the data formats were designed for researchers, with field names and conventions that take some reading to understand.
Guardian Open Platform
The Guardian's Open Platform exposes the same content API that powers the Guardian's websites and apps. A free developer key returns full article bodies with tags and sections back to 1999, and commonly reported limits are about 5,000 calls a day and 12 a second. The key is for non-commercial projects; commercial use needs a deal with Guardian News & Media. Developers like it for teaching because the tagging is consistent and the responses are predictable, which makes it a good dataset for NLP exercises. The obvious limit is that every article comes from one newspaper.
