How do I get my Carta API credentials?

Go to the **Carta Developer Portal** at **developer.carta.com** and log in or register. Click **Create App**, fill in the app details (name, homepage URL, grant type, and required scopes), then click **View app details** to find your **Client ID** and **Client Secret**. Copy both values and paste them into the configuration below. Note: Carta's API program is invite-only — if you don't have access, email **developers@carta.com** to request it.

Can my AI agent tell me exactly how much equity remains in our option pool?

Yes. Ask your agent to pull the cap table and it returns the total authorized shares, shares issued, options granted, options exercised, and the remaining unallocated pool — giving you an instant snapshot of your equity position. Perfect for board meetings, fundraising conversations, or new-hire planning where you need the numbers immediately.

What if a new hire asks about their vesting schedule during onboarding?

Your AI agent can pull any employee's grant details including total shares granted, vesting start date, cliff date, monthly vesting rate, and shares already vested — so HR can answer equity questions instantly during the onboarding call without opening the Carta dashboard or asking Legal.

Can this handle companies with complex multi-round fundraising histories?

Yes. The integration retrieves the full cap table structure including Seed, Series A, B, C rounds and beyond, convertible notes, SAFEs, and all share classes. Perfect for late-stage startups preparing for IPO, companies running secondary sales, and legal teams performing due diligence on cap table complexity.
