Description#

Similar surveys helps you decide the best CPI based on previous studies with common market and audience. You will have the possibility to see the last three surveys with similar audience and check the average CPI.
The API will return the 3 most similar projects in the last 3, 6 or 9 months.
If the global query parameter is used, the AVG CPI shown is the Supplier AVG CPI + the Margin of the account. We will not show the price and the margin applied for another account.
The limits and ranges of this endpoint's criteria are customizable:
Search limit time in day/s)
Complete range ± %
LOI range ± %
IR range ± %
Time range in day/s
Please contact PureSpectrum support for any requested customization.
