Tavily vs Guardian Open Platform: overview
Tavily
Tavily, founded by CEO Rotem Weiss, sells a search API designed for LLM agents. Its topic=news mode limits results to recent news and returns extracted text that can go straight into a prompt. Nebius, the Nasdaq-listed AI cloud company, agreed to buy Tavily in February 2026 (Bloomberg reported a $275 million price) and later said the deal had closed, with the Tavily brand and pricing kept in place. Billing runs on credits: one per basic search, two per advanced search, about $0.008 each on pay-as-you-go, and 1,000 free credits a month. As a search tool it has no news archive, source taxonomy or clustering.
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.
