API Reference

Get Memory

Fetch a single decrypted memory owned by the authenticated principal. The handler enforces tenant + environment + project isolation; rows owned by another user return 404 rather than 403 so the global id space is not leakable.

GET/memory/{memory_id}

Authentication

Accepts a JWT bearer token (Authorization: Bearer eyJ…) or an API key (X-API-Key: ms_live_…). API-key callers should send X-Project-ID unless the key is project-locked. Cross-tenant operators must send X-Tenant-ID.
