+
+[Hindsight Cloud](https://ui.hindsight.vectorize.io/signup) now supports programmatic API key management. API keys with the **Key Creator** capability can create, list, and revoke bank-scoped child keys via the API — no admin or UI access required.
+
+<!-- truncate -->
+
+## What You Can Do
+
+- **Create child keys** — provision short-lived, least-privilege keys scoped to specific banks
+- **Bank scope enforcement** — child keys can only access banks within the parent key's scope
+- **Expiration constraints** — child keys cannot outlive their parent
+- **Cascade revocation** — revoking a parent key automatically revokes all of its children
+- **Immutable children** — programmatically created keys cannot have their bank scope edited; revoke and recreate instead
+- **Audit trail** — all key creation, revocation, and scope changes are logged with actor identity
+
+## Why This Matters
+
+If you're running a multi-tenant setup — one memory bank per customer, per agent, or per environment — you no longer need to manage keys through the dashboard. Your application can provision scoped keys on the fly, rotate them on a schedule, and revoke them instantly when access should end.
+
+Combined with [bank-scoped API keys](/blog/2026/03/09/hindsight-document-upload#what-else-is-new) (released March 9), this gives you a complete least-privilege key hierarchy: a parent key with Key Creator capability manages child keys that are each locked to specific banks.
+
+## Get Started
+
+Programmatic API key management is available now in [Hindsight Cloud](https://ui.hindsight.vectorize.io/signup). Create a key with the Key Creator capability to start provisioning child keys via the API.
