No rate limits here. You'll be able to create images up until you reach your account limit.
By default we render images for high resolution screens. This is known as @2X. This ensures your image looks great on devices like iPhones and high resolution monitors.
You can adjust this back to @1X by setting device_scale:1 when creating your image.
Absolutely. All of our enterprise plans include an SLA. Contact us at [email protected] and we can build a custom plan for your specific needs.

Yes, include the <link> tag to the Font Awesome CDN in your html. You may need to add localhost to your hostname whitelist for us render icons using your account.
We recommend passing the url to your webpage to the API. Learn how to do that here: URL to Image.
Alternatively, when passing your HTML to the API, include the full HTML markup. Starting and ending with the <html> tags. The HCTI API will enter full page mode and render the entire page as displayed by Google Chrome.
Forever. As long as your HCTI account is active, we keep a copy of your generated image stored and accessible from your image url.
Yes, be sure to include the full URL to your external image. The API will load it before creating the image. <img src="https://example.com/yourimage.png" />

All images served by the hcti.io domain are cached by Cloudflare's global content delivery network. Bandwidth is unlimited and paid for as a part of your subscription.
Definitely. If you're a student and using the API to build something cool. Email us and we'd be happy to add free images to your account.
The filename for your image is a randomly generated (and unique!) UUID. We currently do not have the option to set the filename.
The v1/image namespace is shared by everyone who uses the API. Auto generating the file names makes your content more secure (hard to guess). We also use these long keys as partition keys for our infrastructure. This helps us scale the API for creating millions of images each month.
Using UUID's helps us keep the service easy to use, fast and secure. Which is important to us.
We regularly keep HCTI up-to-date with the latest version of Chrome. We run a full test suite to ensure images render as expected before upgrading the API.
Email us! [email protected]. We'd love to hear from you. We're great at debugging rendering issues, send us your toughest problems.
