Exa vs Guardian Open Platform: overview
Exa
Exa Labs was founded in 2021 in San Francisco by Will Bryk and Jeff Wang under the name Metaphor, and raised an $85 million Series B led by Benchmark in September 2025. It runs its own embeddings-based web index. A request can be narrowed to the news category and can return cleaned page contents in the same call. As of 2026 the Search endpoint is listed at $7 per 1,000 requests with contents for the first 10 results included, and new accounts get $20 in credit. Exa is a general web search engine first, so small regional outlets and strict publication-date filters are weaker spots than in dedicated news APIs.
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.
