> 📘 **The minimum bid per currency may*change* from time to time. Make sure to fetch the latest values.**

> 🚧 Minimum CPC Rules
>
> 1. Attempting to apply a *campaign-level* CPC that falls below the minimum will result in **Error 400**.
> 2. Attempting to apply a *site-level* bid that falls below the minimum will result in **Error 400**.
> 3. *During* an auction, the system compares the *site-level bid* to the *allowed minimum* and uses the *higher of the 2*. **This is the bid amount that will be used in auctions, and the value that will be charged for a click.**

> 🚧 Example
>
> Set the *campaign-level* `cpc` to `0.1`:
>
> > Bid for demo-site-1 = `0.1` (*default*)
>
> Apply a `cpc_modification` of `0.5` to *demo-site-1*:
>
> > Bid for demo-site-1 = `0.1 x 0.5 = 0.05`
>
> Adjust the campaign-level `cpc` to `0.01`:
>
> > Bid for demo-site-1 =  `0.01 x 0.5 = 0.005` (*below* the allowed minimum)
>
> For *demo-site-1* bidding, the system will use:
>
> > `MAX(allowed_minimum, site_specific_bid)` = `MAX(0.01, 0.005)` = `0.01`
>
> **This is the bid amount that will be used in auctions, and the value that will be charged for a click.**
