Does KeyCDN have an API?

How is KeyCDN different compared to other CDN providers?
KeyCDN's content delivery architecture has been engineered and developed from square one with simplicity and high performance in mind. Learn more about how KeyCDN is different: CDN Comparison of KeyCDN
What is a Zone?
KeyCDN calls its CDN instances “Zones”. Each zone has individual settings. 2 different types of zones exist such as Push and Pull. A zone is normally needed for one website. A zone is a URL that you can embed in your website for static websites. A zone has nothing to do with geography. All POPs worldwide are enabled for each zone.
What is a Pull Zone?
A Pull Zone fetches (pulls) the requested content from your origin server and caches the assets on our edge servers. In most of the cases, a Pull Zone is the preferred option for any content management system (CMS). Don't use a Pull Zone for files larger than 100MB in size or the assets will not be cached.
What is a Push Zone?
A Push Zone requires that you upload your content to the CDN storage cloud and distribute it from there to the edge servers. We support FTP(S) or rsync over SSH to upload your data. Push Zones are mainly used for distributing files larger than 10MB or for files that rarely change (such as documents, videos, etc).
How long does it take to deploy the Zone settings to the POPs?
It takes just a few minutes. The deployment time is the same for creating or editing a Zone, Zonealias or Zonereferrer.
Do you support shared or custom SSL certificates?
Yes. Simple, SAN and wildcard certificates are supported. Shared and custom SSL certificates are free of charge. Our certificates are based on SNI.
Is it possible to clear (purge) the Pull Zone cache?
Yes, either through the API or in the dashboard.
Is it possible to clear (purge) a single URL in a Pull Zone?
Yes, you can purge a single URL either through the API or in the dashboard.
Can I cache dynamic content?
It depends on the type of content and how you build your application. It is possible by using query strings and Cache-control headers for your assets.
How do I upload my content to a Push Zone?
If you configure a Push Zone you can upload your content via FTP(S) or rsync over SSH. Pull Zones fetch the content from the origin server.
How much is the minimum payment?
The minimum payment is $49, which equals to 49 credits. We don't accept an amount below this. Please note, unused credits expire after 1 year.
How is storage billed?
Push storage pricing starts at $0.47/GB/month (billed on daily basis). There is no storage cost for Pull Zones.
What is the cost for custom SSL?
What happens if a file is only partially downloaded?
The exact downloaded data is charged, not the whole file.
What is a credit?
Credits can be loaded to your account and are used to charge for all kind of different services that we offer such as traffic, storage or consulting fees. One credit equals to one USD.
Will I receive notifications if I'm low on credits?
Yes, we send a reminder when your balance reaches 0. You are allowed to have a negative balance of 40% from your last payment before we stop content delivery. The second reminder will be send if you reach a negative balance of 20% from your last payment. The third and final reminder informs you that your account has been set to inactive and that content delivery has been suspended. At the latest, you will receive the final reminder after 7 days since the first reminder. Make sure you white-list emails send from @keycdn.com to avoid they end up in your spam folder.
What happens when I run out of credits?
If you’ve enabled auto-payment, you’ll be charged again with the amount that you’ve defined. If auto-payment is disabled, you’ll get several emails when you have a negative balance. If you don’t recharge your account after the third reminder email, your account will be set to inactive and content delivery will stop.
We recommend enabling auto-payment.
What threshold does the recharge execute at?
The auto-payment will execute when the balance is 0. If the auto-payment fails, your account will stay active and you’ll have time to conduct a payment.
What happens if the auto-payment fails?
We understand that continuous content delivery is very important. If the auto-payment fails, you’ll get several emails (telling you that you have a negative balance). We don’t block paying customers right away when you ran out of credits. This will give you time to react while content delivery continues for your account.
How can I cancel or terminate my account?
You don’t need to cancel or terminate the account explicitly. If you delete your zones and remove your data on our FTP, you won’t be charged. You can still use your credits later on. If you still want to delete your account, you can do that directly in the dashboard.
