Authentication - Clustr

All API requests require a Bearer token in the Authorization header.

Authorization: Bearer <your_api_key>

Creating an API key

Go to the API settings page
Click Create New Key
Copy the key immediately. It won’t be shown again

You can create up to 10 API keys per workspace.

Example

curl https://api.clustr-ai.com/api/public/target-accounts \
  -H "Authorization: Bearer clstr_abc123..."

import requests

headers = {"Authorization": "Bearer clstr_abc123..."}
response = requests.get(
    "https://api.clustr-ai.com/api/public/target-accounts",
    headers=headers
)

const response = await fetch(
  "https://api.clustr-ai.com/api/public/target-accounts",
  { headers: { Authorization: "Bearer clstr_abc123..." } }
);

req, _ := http.NewRequest("GET",
    "https://api.clustr-ai.com/api/public/target-accounts", nil)
req.Header.Set("Authorization", "Bearer clstr_abc123...")
