​
Authentication

The Scope3 Agentic API v2 uses API keys for authentication. All requests must include a valid API key to access your campaigns, creatives, and other resources.

​
Getting Your API Key

  1. Visit agentic.scope3.com/api-keys
  2. Sign up or log into your Scope3 account
  3. Generate a new API key for your integration
  4. Copy the key - it starts with scope3_
Keep your API key secure! Don’t commit it to version control or share it publicly. Use environment variables or secure key management systems.

​
API Key Format

Scope3 API keys follow this format: 
scope3_<32_character_client_id>_<secret>
Example: scope3_abc123def456ghi789jkl012mno345pq_xyz789

​
MCP Authentication (v2)

For Model Context Protocol integrations with AI agents: Python: 
from mcp.client.streamable_http_transport import StreamableHttpTransport
from mcp.client import Client

transport = StreamableHttpTransport(
    "https://api.agentic.scope3.com/mcp/v2",
    auth="scope3_your_api_key_here",
)

async with Client(transport) as client:
    result = await client.call_tool('health')
    print(result)
