Perplexity

Headless company intelligence

Run `enrich_company` and `enrich_person` directly from your terminal. Claude Code processes these calls in your CI/CD pipeline or shell scripts, feeding data into your downstream tasks. It handles the authentication and tool registry automatically. You just define the workflow and let the agent manage the data flow.

Automated pipeline data fetching

Use `list_funding_rounds` and `list_traction_signals` to keep your internal databases updated. Claude Code triggers these functions on a schedule, piping the results into your processing scripts. This removes the need for manual API management. The agent manages the connection and data ingestion for you.

Systematic investor search

Integrate `search_investors` into your automation scripts to monitor market activity. Claude Code uses the results to update your internal records or notify your team of new matches. It works without a GUI, keeping your terminal clean. You get accurate, machine-readable output every time.
