Install

Manus does not ship an npm package or pip library. Access is via:

1. Web app - sign up at manus.im
2. Desktop app - download from manus.im
3. REST API - no install required; use any HTTP client

Get an API key

1. Sign in to the Manus web app at manus.im.
2. Navigate to Settings > API Integration.
3. Click Create API Key, give it a name, and copy the key immediately (shown only once).
4. Store it as an environment variable:

export MANUS_API_KEY="your_api_key_here"

Each account supports up to 50 API keys. All keys on the same account share one rate-limit counter.

Verify connectivity (no install needed)

curl -s -o /dev/null -w "%{http_code}" \
  https://api.manus.ai/v2/task.list \
  -H "x-manus-api-key: $MANUS_API_KEY"

A 200 response confirms your key is valid and the API is reachable.

OAuth2 option

For third-party apps acting on behalf of users, use OAuth2. The bearer token replaces the API key:

Authorization: Bearer <access_token>

See open.manus.ai/docs/v2/authentication for the full OAuth2 flow.
