GDELT Project vs Guardian Open Platform: overview
GDELT Project
The GDELT Project, created by Kalev Leetaru, is an open research database that monitors broadcast, print and web news worldwide in more than 65 languages and publishes updates every 15 minutes. Its DOC 2.0 API searches recent coverage and returns article lists and timelines, while bulk event and knowledge-graph files can be queried in Google BigQuery. The main APIs are free and need no key. What you get back is metadata and links, so you still have to fetch and parse each page yourself.
Guardian Open Platform
The Guardian's Open Platform gives developers the same content API that runs the Guardian's own sites, with full article bodies, tags and sections going back to 1999. A free developer key is commonly reported at about 5,000 calls a day and 12 calls a second, and it is meant for non-commercial projects. Commercial use needs a separate agreement with Guardian News & Media. Clean, consistent tagging has made it a favourite for teaching and research, though you only ever get one publisher.
