Retrieve probability of fraud for a specific IP, Device, or Agent.
The Fraud Blocking API returns a probability (risk score) 0.01 to 1.0 representing
the likelihood a given value is related to malicious or compromised devices.
This risk scoring is calculated by Pixalate's proprietary machine-learning algorithm and
allows clients to set their own blocking thresholds based on the quality and scale of their supply inventory.
The following is a general guideline for setting fraud blocking thresholds:

• Probability equal to 1.0, for filtering out only the worst offender for blocking (deterministic).
• Probability is greater than or equal to 0.90 for filtering out users that are fraudulent beyond a reasonable doubt.
• Probability between 0.75 (inclusive) and 0.90 (exclusive) to filter out users associated with clear and convincing evidence that they are fraudulent.
• Probability between 0.5 (inclusive) and 0.75 (exclusive) to filter out users that it is more likely than not that they are fraudulent (also known as preponderance of the evidence standard).

Pixalate does not recommend blocking any probabilities less than 0.5.
When making adjustments to the probability threshold, Pixalate highly recommends regular checks and balances against
impression delivery as lowering the probabilistic threshold can potentially impact the impression count.

Zero or more of the following parameters may be provided. If more than one parameter is specified,
the probability returned is determined by assessing risk based on the combination of each parameter's individual risk probability.

Not specifying an IP, Device, or Agent will return the metadata for fraud, including the user's current quota. See alternate response schema below.
