LexisNexis Nexis Data+ vs Guardian Open Platform: overview
LexisNexis Nexis Data+
LexisNexis, part of RELX, moved into news APIs when it acquired Moreover Technologies and its Metabase feed in 2014. Metabase delivers 3–5 million news articles and social posts a day in 90+ languages. The newer Nexis Data+ platform adds 23,000+ licensed publications cleared for generative-AI use, among them The Associated Press, Gannett and the South China Morning Post. Nexis Data+ also exposes dockets, patents, sanctions lists and company records under the same contract, which none of the news-only vendors here can match. Pricing is negotiated.
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.
