Can I create new leads directly through the AI agent?

Yes! The `create_lead` tool accepts a company name and an optional website URL. Your agent will create the lead record in Close and return the new Lead ID for immediate reference.

How does the API authentication work with Close?

Close uses HTTP Basic Authentication. Your API Key is sent as the username with an empty password. Navigate to Settings > Developer > API Keys in your Close dashboard to generate a new key. The key is encrypted at rest and injected securely at runtime.

Can I view my sales opportunities and their current stages?

Yes. The `list_opportunities` tool retrieves all active deals in your pipeline, including stage name, expected value, probability, and projected close date. Combine it with `list_crm_tasks` to check pending follow-ups associated with each opportunity.
