Use it with your agent

Read https://scrollport.com/start. Use my existing Scrollport connection, or help me connect if needed. Help me use Company Search (tool ID: companies-house.company-search). Ask me for the details you need, then show me the result.

Provider access is included. If your agent isn't connected to Scrollport yet, it will help you set that up.

Questions

Is Company Search by Companies House free?

Scrollport has no free tier: it costs $0.0050 per request ($0.50 per 100 requests), paid per use from a prepaid wallet with no subscription. Connecting your first agent adds $1 of trial credit, so you can try it before adding funds.

Do I need an API key from Companies House?

No. Your agent runs it through your Scrollport connection (MCP, the Scrollport CLI or the HTTP API), and Scrollport handles access to Companies House, so you don't sign up with Companies House or manage an API key.
