Introducing Web Search API via AI Gateway

What happened

Cloudflare AI Gateway now supports native web search API (the interface one piece of software uses to talk to another) integration in partnership with Ceramic.ai, Exa, and Linkup. This is why you’ll sometimes see web fetches come back with a 404 Not Found, which happens if the agent incorrectly guesses the URL of that information.

Developers can now inject real-time web context into model inference (running a trained model to get an answer, rather than training it) calls via AI Gateway, REST APIs, or Workers bindings. Fun fact: when you use an agent and it needs to fetch a live web page, the agent usually just guesses the URL of the page and then makes a tool call to curl it.

As you can imagine, it’s not super efficient to randomly guess URLs all the time. This is what web search is designed to do — it enables agents to search for relevant data on the Internet and grounds an agent’s responses based on live information.
