Tavily vs Guardian Open Platform: overview
Tavily
Tavily, founded by CEO Rotem Weiss, is a search API designed to be called by LLM agents, and its topic=news mode limits results to recent coverage with extracted text ready for a prompt. It is the quickest way on this list to give a LangChain or LlamaIndex agent a news tool, since both frameworks ship Tavily integrations. Nebius, the Nasdaq-listed AI cloud company, agreed to buy Tavily in February 2026 (Bloomberg put the price at $275 million) and later said the deal had closed, keeping the brand and pricing. Credits cost about $0.008 each on pay-as-you-go, a basic search uses one and an advanced search two, and 1,000 credits a month are free. Because it is a search tool, there is no archive, source list or clustering to work with.
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.
