Example 1: Complete Data, Unlikely Fraud

This example demonstrates a request with all data fields filled, which returns a 200 response and indicates that fraud is unlikely.

curl --request GET \
     --url 'https://api.atdata.com/fr?api_key=<YOUR_API_KEY>&email=example%40atdata.com&reference_id=123_456_789&first=John&last=Doe&street=123%20Main%20St&city=New%20York&state=NY&zip=123456&country=US&phone=123456789&ip=1.2.3.4&user_agent=python-requests%20F2.27.1' \

}

Example 2: Complete Data, Likely Fraud

Here, a request is sent with complete data similar to the first example, but it returns a 200 response that indicates a likely fraudulent email. This example helps with understanding how different data inputs can affect fraud assessment.

curl --request GET \
     --url 'https://api.atdata.com/fr?api_key=<YOUR_API_KEY>&email=example%40atdata.com&reference_id=123_456_789&first=John&last=Doe&street=123%20Main%20St&city=New%20York&state=NY&zip=123456&country=US&phone=123456789&ip=1.2.3.4&user_agent=python-requests%20F2.27.1' \
     --header 'accept: application/json'

      "zip_match": "no_data",
      "city_match": "no_data",

    }
  },
  "email_validation": {
    "domain_type": "biz",
    "status_code": 45,
    "address": "[email protected]",
    "status": "unverifiable"
  }
}

Example 3: Email Only, Unlikely Fraud

This request includes only the email address, returns a 200 response, and suggests that fraud is unlikely, showcasing how the API handles minimal data inputs.

curl --request GET \
     --url 'https://api.atdata.com/fr?api_key=<YOUR_API_KEY>&email=example%40atdata.com' \
     --header 'accept: application/json'

{
  "eam": {
    "longevity": 3,
    "velocity": 0,
    "date_first_seen": "2011-04-04",
    "popularity": 0
  },
  "dam": {
    "longevity": 3,
    "velocity": 10,
    "date_first_seen": "2002-11-09",
    "popularity": 10
  },
  "risk": {
    "score": 1,
    "query_id": "9aef8719-e1cf-4a1e-afea-9e2764b716d0",
    "tumbling_risk": 0,
    "domain": {
      "domain_risk_score": 0
    }
  },
  "email_validation": {
    "domain_type": "freeisp",
    "status_code": 50,
    "address": "[email protected]",
    "status": "valid"
  }
}

Example 4: Email Only, Likely Fraud

Similar to the previous one, this example involves a request with just an email address but returns a 200 response where fraud is deemed likely, helping users see how the API evaluates risk based solely on email.

curl --request GET \
     --url 'https://api.atdata.com/fr?api_key=<YOUR_API_KEY>&email=example%40atdata.com' \
     --header 'accept: application/json'

{
  "eam": {
    "longevity": 0,
    "velocity": 0,
    "date_first_seen": "now",
    "popularity": 0
  },
  "dam": {
    "longevity": 2,
    "velocity": 0,
    "date_first_seen": "2024-02-09",
    "popularity": 0
  },
  "risk": {
    "score": 99,
    "query_id": "9aef8719-e1cf-4a1e-afea-9e2764b716d0",
    "tumbling_risk": 0,
    "domain": {
      "domain_risk_score": 10
    }
  },
  "email_validation": {
    "status_code": 50,
    "address": "[email protected]",
    "status": "valid"
  }
}

Example 5: Incorrectly Filled Email, Email Correction

A request with an incorrectly filled email address that returns a 200 response, including a suggestion of possible email address correction. It illustrates the API’s ability to suggest corrections to possible incorrectly informed emails. In this example, the email is incorrectly typed as [email protected].

curl --request GET \
     --url 'https://api.atdata.com/fr?api_key=<YOUR_API_KEY>&email=example%40atdata.co' \
     --header 'accept: application/json'

{
  "eam": {
    "longevity": 0,
    "velocity": 0,
    "date_first_seen": "now",
    "popularity": 0
  },
  "dam": {
    "longevity": 0,
    "popularity": 0,
    "velocity": 0
  },
  "risk": {
    "score": 100,
    "query_id": "a789df02-5b11-4361-a740-b778708c4595",
    "tumbling_risk": 0,
    "domain": {
      "domain_risk_score": 10
    }
  },
  "email_validation": {
    "status_code": 325,
    "address": "[email protected]",
    "email_corrections": [
      "[email protected]"
    ]
    "status": "invalid"
  }
}

Example 6: Incorrect Email, Invalid Status

This example presents a request with an incorrect email address that yields a 200 response, which returns an invalid status for the email address. This example demonstrates how the system deals with invalid email addresses for which it does not have a suggestion for correction. In this example, the email was filled in as notanactualemail.

curl --request GET \
     --url 'https://api.atdata.com/fr?api_key=<YOUR_API_KEY>&email=notanactualemail' \
     --header 'accept: application/json'

{
  "email_validation": {
    "status_code": 150,
    "address": "notanactualemail",
    "status": "invalid"
  }
}

Example 7: Missing Email

Shows a request submitted without an email address, resulting in a 400 response for a missing query parameter, highlighting how the API enforces required fields.

curl --request GET \
     --url 'https://api.atdata.com/fr?api_key=<YOUR_API_KEY>' \
     --header 'accept: application/json'

Missing query parameter(s).

Example 8: Incorrect API Key

This example shows a request made with an incorrect API key that leads to a 401 response, indicating an invalid API key. In this example, the API key is <INVALID_API_KEY>.

curl --request GET \
     --url 'https://api.atdata.com/fr?api_key=\<INVALID_API_KEY>&email=example%40atdata.com' \
     --header 'accept: application/json'

Invalid API key.
