Memory Operations - Supermemory

<Info> These v4 endpoints operate on extracted memories (not raw documents). SDK support coming soon — use fetch or cURL for now.

For document management (list, get, update, delete), see Document Operations. For ingesting raw content (text, files, URLs) through the processing pipeline, see Add Context. </Info>

Create Memories

Create memories directly without going through the document ingestion workflow. Memories are embedded and immediately searchable.

This is useful for storing user preferences, traits, or any structured facts where you already know the exact memory content.

<Tabs> <Tab title="fetch"> ```typescript const response = await fetch("https://api.supermemory.ai/v4/memories", { method: "POST", headers: { "Authorization": `Bearer ${API_KEY}`, "Content-Type": "application/json" }, body: JSON.stringify({ memories: [ { content: "John prefers dark mode", isStatic: false, metadata: { source: "user_preference" } }, { content: "John is from Seattle", isStatic: true } ], containerTag: "user_123" }) });

const data = await response.json();
// {
//   documentId: "abc123",
//   memories: [
//     { id: "mem_1", memory: "John prefers dark mode", isStatic: false, createdAt: "2025-..." },
//     { id: "mem_2", memory: "John is from Seattle", isStatic: true, createdAt: "2025-..." }
//   ]
// }
```

</Tab> <Tab title="cURL"> ```bash curl -X POST "https://api.supermemory.ai/v4/memories" \ -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "memories": [ { "content": "John prefers dark mode", "isStatic": false, "metadata": { "source": "user_preference" } }, { "content": "John is from Seattle", "isStatic": true } ], "containerTag": "user_123" }' ``` </Tab> </Tabs>

Parameters

Parameter	Type	Required	Description
`memories`	array	yes	Array of memory objects (1–100 items)
`memories[].content`	string	yes	The memory text (max 10,000 chars). Should be entity-centric, e.g. "John prefers dark mode"
`memories[].isStatic`	boolean	no	`true` for permanent identity traits (name, hometown). Defaults to `false`
`memories[].metadata`	object	no	Key-value metadata (strings, numbers, booleans)
`containerTag`	string	yes	Space / container tag these memories belong to

Response

json

{
  "documentId": "abc123",
  "memories": [
    {
      "id": "mem_1",
      "memory": "John prefers dark mode",
      "isStatic": false,
      "createdAt": "2025-01-15T10:30:00.000Z"
    }
  ]
}

Field	Type	Description
`documentId`	string \| null	ID of the lightweight source document created for traceability
`memories`	array	The created memory entries
`memories[].id`	string	Unique memory ID
`memories[].memory`	string	The memory content
`memories[].isStatic`	boolean	Whether this is a permanent trait
`memories[].createdAt`	string	ISO 8601 timestamp

<Tip> **When to use this vs [Add Context](/add-memories)?**

Use Create Memories when you already know the exact facts to store (user preferences, traits, structured data). Use Add Context when you have raw content (conversations, documents, URLs) that Supermemory should process and extract memories from. </Tip>

Forget Memory

Soft-delete a memory — excluded from search results but preserved in the system. Use this when you might want to restore later.

<Tabs> <Tab title="fetch"> ```typescript await fetch("https://api.supermemory.ai/v4/memories/mem_abc123/forget", { method: "POST", headers: { "Authorization": `Bearer ${API_KEY}` } }); ``` </Tab> <Tab title="cURL"> ```bash curl -X POST "https://api.supermemory.ai/v4/memories/mem_abc123/forget" \ -H "Authorization: Bearer $SUPERMEMORY_API_KEY" ``` </Tab> </Tabs>

The memory will no longer appear in search results but remains in the database.

Update Memory (Versioned)

Update a memory by creating a new version. The original is preserved with isLatest=false.

<Tabs> <Tab title="fetch"> ```typescript await fetch("https://api.supermemory.ai/v4/memories", { method: "PATCH", headers: { "Authorization": `Bearer ${API_KEY}`, "Content-Type": "application/json" }, body: JSON.stringify({ // Identify by ID or content id: "mem_abc123", // content: "Original content to match",

    newContent: "Updated content goes here",
    metadata: {
      tags: ["updated"]
    }
  })
});
```

</Tab> <Tab title="cURL"> ```bash curl -X PATCH "https://api.supermemory.ai/v4/memories" \ -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "id": "mem_abc123", "newContent": "Updated content goes here", "metadata": {"tags": ["updated"]} }' ``` </Tab> </Tabs>

Parameters

Parameter	Type	Required	Description
`id`	string	*	Memory ID to update
`content`	string	*	Original content to match (alternative to ID)
`newContent`	string	yes	New content for the memory
`metadata`	object	no	Updated metadata

* Either id or content must be provided.
