The Snyk API is available to customers on paid plans and allows you to programatically integrate with Snyk.
API vs CLI vs Snyk integration
The API detailed below has the ability to test a package for issues, as they are defined by Snyk. It is important to note that for many package managers, using this API will be less accurate than running the Snyk CLI as part of your build pipe, or just using it locally on your package. The reason for this is that more than one package version fit the requirements given in manifest files. Running the CLI locally tests the actual deployed code, and has an accurate snapshot of the dependency versions in use, while the API can only infer it, with inferior accuracy. It should be noted that the Snyk CLI has the ability to output machine-readable JSON output (with the --json flag to snyk test).
A third option, is to allow Snyk access to your development flow via the existing Snyk integrations. The advantage to this approach is having Snyk monitor every new pull request, and suggest fixes by opening new pull requests. This can be achieved either by integrating Snyk directly to your source code management (SCM) tool, or via a broker to allow greater security and auditability.
If those are not viable options, this API is your best choice.

The Computer Vision API provides state-of-the-art algorithms to process images and return information. For example, it can be used to determine if an image contains mature content, or it can be used to find all the faces in an image. It also has other features like estimating dominant and accent colors, categorizing the content of images, and describing an image with complete English sentences. Additionally, it can also intelligently generate images thumbnails for displaying large images effectively.
