Crustdata Web Search API: Best Way to Give AI Agents Real Web Results
If you are building an AI agent, you already know the hard part: the agent needs the web.
But regular search tools are made for humans. An AI agent needs search that is fast, clean, and easy to control. That is what Crustdata Web Search API is made for. Crustdata says this API turns the web into structured, live data for AI agents.
In this guide, you will learn what it is, what it does, and when to use it.

What you can control in search results
When an agent searches the web, you often want rules like: “only show results from these sites” or “only show posts from the last day.”
Crustdata highlights controls such as filtering by:
- website domains
- date posted
- sources
- geo location
This is useful for building repeatable workflows, not one-off searches.
Search is step one. Reading pages is step two.
Search results are only the start. Your agent usually needs the page content too.
Crustdata has a Web Fetch API that fetches a page’s title and full HTML from a list of URLs, and it supports up to 10 URLs in one request.
This matters for tasks like:
- turning web pages into text for RAG
- pulling product docs or pricing pages
- saving sources for later review
Where this fits in an AI stack (in plain words)
If you are building anything like:
- a RAG system (Retrieval-Augmented Generation)
- a research assistant
- an agentic workflow that runs steps automatically
…you often need the same flow:
- Search the web
- Pick good sources (using domain + date filters)
- Fetch page content
- Clean the text
- Store or summarize it
- Use it in answers, reports, or actions
Crustdata’s Web Search API + Web Fetch API cover steps 1 and 3.
