With Google and Bing, we failed - notfor lack of trying.
Bing: Their terms didn’t work for us from the start. Microsoft’s terms prohibited reordering results or merging them with other sources - restrictions incompatible with Kagi’s approach. In February 2023, they announced price increases of up to10x on some API tiers. Thenin May 2025, they retired the Bing Search APIs entirely, effective August 2025, directing customers toward AI-focused alternatives like Azure AI Agents.
Google: Google does not offer a public search API. The only available path is an ad-syndication bundle with no changes to result presentation - the model Startpage uses.
