headers = {"Authorization": f"bearer {API_KEY}", "X-Odoo-Database": "your-db"}

res = requests.post(
    f"{BASE_URL}/mail.activity.mixin/search_read",
    headers=headers,
    json={"domain": [], "fields": ["activity_type_id","activity_summary","activity_type_icon"], "limit": 5},

XML-RPC and JSON-RPC will be removed in Odoo 22 (fall 2028): use JSON-2.
The access rights and record rules of the key's user apply.
