What is Web search API by Crustdata?

Web search API by Crustdata is a specialized search interface designed to give AI agents fast, accurate access to the entire web. Unlike general-purpose search APIs, it lets you filter results by website domain, publication date, source type, and geographic location. You can search news articles and social posts published as recently as one hour ago, find open source creators and research paper authors, and even get precise answers through a deep research mode. When paired with Crustdata's fetch API, you can extract full page content from any result.

Who it's for

• AI developers building agents that need real-time, filtered web data without scraping or maintaining crawlers
• Sales and GTM teams who want to enrich leads with live signals like recent hires, promotions, or funding events
• Recruiters and investors tracking movements of specific people, companies, or industry trends across news and social sources

Key features

Domain and source filtering

Control exactly where your search results come from by specifying allowed website domains, source types (news, social, blogs), and geographic regions. This eliminates noise and keeps your AI agent focused on relevant content.

Real-time freshness

Search across articles and social posts published within the last hour. This is critical for agents that need to act on breaking news, competitor announcements, or time-sensitive signals.

Deep research mode

Instead of returning a list of links, deep research mode analyzes the web to provide direct, concise answers to your query. This saves your agent from having to parse multiple pages to find the information it needs.

Creator and author discovery

Find open source creators and authors of research papers by name or topic. This is especially useful for recruitment platforms and investment tools that need to identify and track key individuals.

What stands out

"The only platform providing truly real-time data."

Crustdata's web search API is built on a data pipeline that refreshes continuously, not just daily or weekly. This means your AI agent can act on changes—like a promotion, a new hire, or a funding round—within minutes of them happening. Combined with the ability to filter by domain, date, and geography, you get a search layer that is both fast and precise, without the overhead of managing your own crawlers.

Worth checking out if…

You are building an AI agent for sales, recruitment, investment, or competitive intelligence that needs live, filtered web data. If your use case requires searching news and social posts from the past hour, finding specific creators or authors, or getting direct answers instead of link lists, this API is a strong fit. It also pairs well with Crustdata's people and company data APIs for enriched workflows.
