Crustdata

Search runs over the indexed dataset of 1B+ people and 60M+ companies, and it favors intent over filter menus. You describe the companies or people you want, such as US firms with at least 50 employees and a recent raise, and the API returns matching records. Search endpoints stay low-cost on purpose, so you can narrow a list before spending credits on enrichment.

Enrichment starts with a company or person you already have and adds fresh attributes on demand. A person enrich call begins with a base profile and adds cost only when you request higher-value data, such as verified business or personal emails, phone numbers or developer profiles. This keeps spend tied to the fields you actually need.

The MCP server exposes 40 tools covering search, enrichment, job signals, social posts and web research, and it works with Claude, Cursor and any MCP client. Your agent calls these tools from a plain-English prompt instead of code, which shortens the path from a question to a usable list. It ships alongside skill templates and a free sandbox key.

The Watcher API pushes a notification the moment a tracked company, person or event changes. You follow job changes, funding rounds or new hires and get the alert through a webhook rather than polling for updates. That timing matters when a signal is only useful before a competitor spots it.

Beyond structured records, Crustdata runs web search across news, web, scholar and social sources, and indexes social posts by text, author and engagement. You can fetch the HTML content of a URL or pull recent posts for a person or company. This gives agents a way to gather context that a profile field alone would miss.

For teams that want no integration work, Crustdata delivers a flat-file dataset of companies and people, refreshed monthly and unified from 11+ sources, as CSV or JSON. Companies filter it by funding, stage, headcount or industry, then load it into analytics or ML pipelines. The same data also flows into internal sales tools and CRMs.
