Exa vs Guardian Open Platform: overview
Exa
Exa Labs started in San Francisco in 2021 as Metaphor, founded by Will Bryk and Jeff Wang, and raised an $85 million Series B led by Benchmark in September 2025. It runs its own web index searched by meaning, so a query like "startups cutting cloud costs" can match articles that never use those words. Set the category to news and ask for contents, and one request returns cleaned text you can drop into a prompt. As of 2026 search costs $7 per 1,000 requests with contents for the top 10 results included, and new accounts start with $20 of credit. SDKs cover Python and TypeScript, and an official MCP server plugs it into agent tools. It is a search engine at heart, so expect weaker coverage of small regional outlets and fuzzier publication dates than a dedicated news API gives.
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.
