Authentication - supermemory | Memory API for the AI era

API Keys

All API requests require authentication using a Bearer token. Get your API key from the Developer Platform. Include your key in all requests:

curl https://api.supermemory.ai/v3/search \
  --header 'Authorization: Bearer YOUR_API_KEY' \
  --header 'Content-Type: application/json' \
  -d '{"q": "hello"}'

import Supermemory from "supermemory";

const client = new Supermemory({ apiKey: "YOUR_API_KEY" });

from supermemory import Supermemory

client = Supermemory(api_key="YOUR_API_KEY")

Connector Branding

When users connect external services (Google Drive, Notion, OneDrive), they see a “Log in to Supermemory” prompt by default. You can replace this with your own app name by providing your own OAuth credentials via the settings endpoint.

await client.settings.update({
  googleDriveCustomKeyEnabled: true,
  googleDriveClientId: "your-client-id.apps.googleusercontent.com",
  googleDriveClientSecret: "your-client-secret"
});

This works for Google Drive, Notion, and OneDrive. See the full setup in Customization.

Scoped API Keys

Container-scoped keys

Scoped keys are restricted to a single containerTag. They can only access documents and search within that container — useful for giving limited access to specific projects, users, or tenants without exposing your full API key.Allowed endpoints: /v3/documents, /v3/memories, /v4/memories, /v3/search, /v4/search, /v4/profile

Create a scoped key

curl https://api.supermemory.ai/v3/auth/scoped-key \
  --request POST \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer YOUR_API_KEY' \
  -d '{
    "containerTag": "my-project",
    "name": "my-key-name",
    "expiresInDays": 30
  }'

Parameters

Parameter	Required	Default	Description
`containerTag`	Yes	—	Alphanumeric, hyphens, underscores, colons, dots
`name`	No	`scoped_{containerTag}`	Display name for the key
`expiresInDays`	No	—	1–365 days
`rateLimitMax`	No	`500`	Max requests per window (1–10,000)
`rateLimitTimeWindow`	No	`60000`	Window in milliseconds (1–3,600,000)

Response

{
  "key": "sm_orgId_...",
  "id": "key-id",
  "name": "scoped_my-project",
  "containerTag": "my-project",
  "expiresAt": "2026-03-08T00:00:00.000Z",
  "allowedEndpoints": ["/v3/documents", "/v3/memories", "/v4/memories", "/v3/search", "/v4/search", "/v4/profile"]
}

Use the returned key exactly like a normal API key — it just won’t work outside its container scope.

Disable a scoped key

To revoke a scoped key, send a DELETE request with the id returned at creation time. This disables the key immediately — any subsequent requests using it will get a 401. Memories and container tags are not affected.

curl https://api.supermemory.ai/v3/auth/scoped-key/KEY_ID \
  --request DELETE \
  --header 'Authorization: Bearer YOUR_API_KEY'

Response:

{ "success": true }
