Can I use the same API Key on multiple websites?
Yes, you can!! As long as you have available credits from a monthly plan or a credit package, you can use a single API Key on as many websites as you want.
Please note that with an Unlimited plan you can still use the same API Key for as many websites as you want, but only the domain you link as unlimited will use your unlimited credits. For the other domains, your one-time credits from your credit packages will be used.
