Anthropic Developer Platform: API Key Expiration, Memory API Improvements, and Managed Agents Enhancements

What is new

• API Key Expiration (Jul 24): In the Claude Console you can now set expiration when creating an API key — preset, custom duration, or Never. For keys with 7+ day lifetime, Anthropic sends an email reminder before expiration. Applies to Admin API keys too.
• Memory API (Jul 24): The agent-memory-2026-07-22 beta header adds stable server-defined ordering to memory listing, tightening depth, path_prefix, and cursor behavior.
• Claude Managed Agents (Jul 22): Effort level settings for agent model configuration, expanded webhook coverage for environment and memory store lifecycle events, and session seeding with initial events (up to 50 per session).

Why it matters

API key expiration is a long-awaited security feature for enterprise deployments — eliminating the problem of forgotten never-expiring keys. Memory API stabilization is critical for production agentic applications relying on consistent results.

How to try it
