SuiteCRM Version 7.9.8 Sugar Version 6.5.25 (Build 344)

Hello all,
I want to retrieve an account using the email address via api call.
I use the following API call :

xxx.xxx.xxx.xxx/SuiteCRM/service/v4_1/rest.php?method=get_entry&input_type=JSON&response_type=JSON&rest_data=

{"session":"8bxxxfjg2hc0dxxxku5d3lo1n5", 
 "module_name":"Accounts", "query":"accounts.email1 = '{{email address}}' ",
"order_by":"",
"offset":"0",
 "select_fields":[], 
 "link_name_to_fields_array":[],
 "max_results":"100", 
 "deleted":"0", 
 "favorites":"false"
 }

It returns null or it doesn’t returns anything.
What is wrong?
