With Snapsbrew's signed URLs you will spend only one credit per image generated, it doesn't matter how many times the url is called if the variants are never changed.
-
Generated synchronously
- Your image is generated in a couple of seconds, no need to wait for a webhook.
-
Generated only once
- Your image is generated the first time, and served from a CDN after that.
-
Signed URL == API
- If you can generate it with Snapsbrew's API, you can generating with signed URLs.
-
Perfect for social cards
- No need to spend credits if your page is not shared on a social network.
Super secure, super easy
Build your variants object and encrypt it with your API key. Snapsbrew will validate your url before spending your credits.
