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.

This API provides current weather information for US Cities, including temperatures, wind speeds, wind direction, relative humidity, and visibility.

This API provides a similarity key used to match with other similar full name data when data fields are parsed into first name and last name components, including for purposes of deduplication, fuzzy matching, or merging of datasets. A much higher match rate will be achieved by matching on the similarity key rather than the data itself. This API is for full name data where first and last name are in separate fields. Use the Full Name Similarity Key API for first and last name data that are in the same field.

The Video Search API lets you search on Bing for video that are relevant to the user's search query, for insights about a video or for videos that are trending based on search requests made by others. This section provides technical details about the query parameters and headers that you use to request videos and the JSON response objects that contain them. For examples that show how to make requests, see Searching the Web for Videos.
