Developers

Every SDK, API, and agent tool FounderHQ has, in one list.

Each product keeps its own SDK and API pages next to its guides. This page is the map across all of them.

Keys

Every SDK and API call carries a key. A key belongs to one brand.

Create and revoke keys in Settings → API Keys. FounderHQ shows the full key once, when you create it.
