Improve Agent Reliability Using the New Memory Beta Header
Enable stable memory listing for smarter, consistent AI agents.
Adopt the 'agent-memory-2026-07-22' beta header in your Claude API calls to ensure memory retrieval results are returned in a stable, predictable order.
The Scenario
You are building an AI agent that needs to retrieve previous user context (memories) and you want the data to return in a consistent, reliable order.
Before & after
Developers had to manually sort returned memory segments in their own code to ensure chronological or logical consistency, adding 30+ minutes of logic-building per project.
By spending 5 minutes switching to the 'agent-memory-2026-07-22' header, you gain a stable, server-defined sorting order that makes your multi-turn chat applications more predictable.
The Prompt
Update your API call headers to include: 'anthropic-beta': 'agent-memory-2026-07-22'. Ensure your 'path_prefix' logic ends with a '/' to match the new whole-path segment requirement.
The new beta header changes how the 'list memories' endpoint behaves, enforcing a stable order and simplifying parameters like 'depth' and 'path_prefix' to prevent unexpected data structures.
