Atomx offers clients to connect via API. All necessary information can be found here:  If you limit the usage of your API to reporting only, first you need to authenticate. This is a sample:

$ curl '' -H 'Content-Type: application/json;charset=UTF-8' --data-binary '{"password":"pass_wd_here","email":""}'

With this login you get a token back, which you use to run a report. Here is a sample report API call:

$ curl '' -H 'Content-Type: application/json;charset=UTF-8' -H 'Authorization: Bearer YOUR_TOKEN_HERE' --data-binary '{"scope":"advertiser","emails":[],"groups":[],"metrics":["impressions","clicks","conversions","campaign_cost"],"where":[["advertiser_id","IN",["1234"]]],"from":"2016-08-17 00:00:00","to":"2016-08-18 00:00:00","timezone":"UTC"}'
