Maintain Stable AI Agent Memory with Current Beta Headers
Switch to the latest beta header for stable memory list ordering.
Implement the 'agent-memory-2026-07-22' beta header when calling Claude Memory Store APIs to ensure stable data ordering and avoid 400 errors.
The Scenario
You are developing an AI agent that uses long-term memory and need to ensure that listing memories remains consistent and stable as the platform updates.
Before & after
Developers used 'managed-agents-2026-04-01' with inconsistent results and manual sorting logic, requiring 1–2 hours of testing for each pagination implementation.
Update your API headers to 'agent-memory-2026-07-22' to ensure stable, server-defined ordering and correct path prefix matching in 5–10 minutes.
The Prompt
I am currently using the [managed-agents-2026-04-01] beta header for Claude memory stores. Please explain how I should refactor my [PYTHON/TYPESCRIPT] code to switch to [agent-memory-2026-07-22], specifically regarding how I handle 'depth' and 'path_prefix'.
The new beta header changes how memories are listed. It enforces a stable server-defined order and restricts the 'depth' parameter to 0 or 1. If you are using SDKs (Python, TS, Go, etc.), they likely already send this header in recent versions, but custom API calls must be updated manually.
