The Engine has three memory stores — episodes, knowledge, and the social graph — plus a “soul” representing the user’s core identity and learned patterns. Memory updates as the agent runs; these endpoints let you read and move it. All memory endpoints require X-Engine-Key.

​
POST /memory/knowledge/search

Search the knowledge store with hybrid (vector + keyword) scoring. 
POST /memory/knowledge/search
Content-Type: application/json

{
  "query": "what does the user prefer for testing?",
  "limit": 20
}
FieldTypeRequiredDefaultPurpose
querystringyes—The natural-language query.
limitintno20Max results (1–100).
Response is an array of knowledge facts: 
[
  {
    "id": "...",
    "subject": "testing",
    "content": "User prefers integration tests against real DB, not mocks.",
    "type": "rule",
    "confidence": 0.92,
    "source": "trajectory:...",
    "valid_from": "2026-01-15T...",
    "valid_until": null
  }
]

​
POST /memory/episodes/search

Same shape as knowledge search. Returns episodes — past events, conversations, outcomes. 
POST /memory/episodes/search
{ "query": "what did we ship last week?", "limit": 10 }

​
POST /memory/social/search

Search the social graph (people, relationships). 
POST /memory/social/search
{ "query": "who introduced the user to MCP?", "limit": 5 }

​
GET /memory/soul

Get a summary of the soul. 
{
  "identity": "...",
  "values": ["..."],
  "patterns": ["..."]
}

​
GET /memory/soul/full

Same as /memory/soul but with all metadata and history. Larger payload.

​
GET /memory/export

Export the entire memory as a portable JSON bundle. Useful for backup or migration to a new Engine instance. Response is an opaque JSON blob — pass it back to /memory/import to restore.

​
POST /memory/import

Import a memory bundle previously produced by /memory/export. 
POST /memory/import
Content-Type: application/json

{
  "bundle": { /* the export payload */ }
}
Response indicates success and counts of imported records.
