  "content": "Updated content here.",
  "meta": { "topic": "database", "reviewed": true },
  "tree": "notes.postgres",
  "temporal": null,
  "hasEmbedding": true,
  "createdAt": "2025-04-15T12:00:00Z",

  "updatedAt": "2025-04-15T14:00:00Z"

See me_memory_create for the full field reference.

Example

Update only the content, keep everything else:

{
  "id": "0194a000-0001-7000-8000-000000000001",
  "content": "PostgreSQL 18 supports native UUIDv7 via the uuidv7() function.",
  "meta": null,
  "tree": null,
  "temporal": null
}

Notes

• meta is fully replaced, not merged. If you want to add a key, fetch the current meta first, merge locally, then send the full object.
• Updating content triggers a new embedding computation. hasEmbedding may temporarily become false.
• Returns an error if the memory does not exist.
