deps.dev API

Overview

The deps.dev API provides access to Open Source Insights data. It can be used by tool builders, researchers, and tinkerers who want to answer questions like:

What versions are available for this package?
What are the licenses that cover this version of a package?
How many dependencies does this package have? What are they?
What versions of what packages correspond to this file?

The API can be accessed in two ways: as JSON over HTTP, which is described on this page, as well as via gRPC. For more information about accessing the API via gRPC, please visit github.com/google/deps.dev.

Using the API

You can access the API using any HTTP client. To quickly get started, you can use the curl command-line tool.

The methods of the API accept parameters. For methods that use the HTTP GET verb, required parameters are passed as part of the request path, while optional parameters are passed as part of the query string. For methods that use the HTTP POST verb, parameters are passed in the request body as a JSON object.

All path and query parameters must be encoded so that they can be safely included in a URL, by replacing special characters (e.g. /) with their percent-encoded forms (e.g. %2F). How this is done depends on your programming language of choice, but as an example, path parameters can be encoded using encodeURIComponent in JavaScript or url.PathEscape in Go, while for query parameters you could use URLSearchParams in JavaScript or url.Values in Go.

For example, to get information about the npm package @colors/colors (note that the @ and / in the package name have been percent-encoded):

curl 'https://api.deps.dev/v3alpha/systems/npm/packages/%40colors%2Fcolors'

Purl parameters

Some methods accept purls, or package URLs, which have their own rules about how components should be encoded. When passing purls as path parameters, clients should first create them using their purl implementation of choice, then percent-encode them in their entirety.

For example, the npm package @colors/colors has the purl pkg:npm/%40colors/colors. To get information about this package:

curl 'https://api.deps.dev/v3alpha/purl/pkg%3Anpm%2F%2540colors%2Fcolors'

Data parameters

Parameters representing data blobs, such as hash values, are passed as base64 strings.

For example, to use the Query API method to look up package versions by file content hash (note that the / and = have been percent-encoded):

curl 'https://api.deps.dev/v3alpha/query?hash.type=SHA1&hash.value=ulXBPXrC%2FUTfnMgHRFVxmjPzdbk%3D'

To compute a base64-encoded hash from a file’s contents suitable for use as a hash.value query parameter you can use the openssl and base64 commands:

openssl sha1 -binary <file> | base64

Batch methods

Batch methods let clients request information on multiple package versions or projects in a single request. These methods use the HTTP POST verb, and parameters are passed as JSON in the request body.

For example, to request information about two package versions in a single request:

curl -d @- 'https://api.deps.dev/v3alpha/versionbatch' <<EOF
{
  "requests":[
    {"versionKey":{"system":"NPM","name":"@colors/colors","version":"1.5.0"}},
    {"versionKey":{"system":"NUGET","name":"castle.core","version":"5.1.1"}}
  ]
}
EOF

Note: batch methods are limited to a maximum of 5000 requests in a batch. Sending more than 5000 requests will result in a 400 error.

Package names

In general, the API refers to packages by the names used within their ecosystem, including details such as capitalization.

Exceptions:

Maven names are of the form <group ID>:<artifact ID>, for example org.apache.logging.log4j:log4j-core.
PyPI names are normalized as per PEP 503.
NuGet names are normalized through lowercasing according to the Package Content API request parameter specification. Versions are normalized according to NuGet 3.4+ rules.

Upstream sources sometimes use multiple, non-identical identifiers to refer to a package and version. These identifiers are served in their pre-normalized form in the upstream identifiers field of the Version message if they were encountered when syncing a package version.

Coverage

In general, the service collects all publicly-available data from each source (for example, it gathers all npm packages hosted by registry.npmjs.org).

Exceptions:

For Maven packages, in addition to Maven Central, it gathers artifacts from the Jenkins and Google registries.
For PyPI it only collects packages released as wheels and sdists.
For Go it only collects modules that have been fetched through proxy.golang.org, and those declared as dependencies by those modules.
For projects hosted on GitHub, GitLab, and Bitbucket it only gathers projects associated with a package otherwise known to the service.

GetDependencies

GET /v3alpha/systems/{versionKey.system}/packages/{versionKey.name}/versions/{versionKey.version}:dependencies

GetDependencies returns a resolved dependency graph for the given package version. Dependencies are currently available for Go, npm, Cargo, Maven and PyPI.

Dependencies are the resolution of the requirements (dependency constraints) specified by a version.

The dependency graph should be similar to one produced by installing the package version on a generic 64-bit Linux system, with no other dependencies present. The precise meaning of this varies from system to system.

Example: /v3alpha/systems/npm/packages/react/versions/18.2.0:dependencies

Path parameters

versionKey.system: string

The package management system containing the package.

Can be one of GO, NPM, CARGO, MAVEN, PYPI, NUGET.

Response

nodes[]: object[]

The nodes of the dependency graph. The first node is the root of the graph.

The package version represented by this node. Note that the package and version name may differ from the names in the request, if provided, due to canonicalization.

In some systems, a graph may contain multiple nodes for the same package version.

For bundled dependencies, the package name in the version key encodes how the dependency is bundled. As an example, a bundled dependency with a name like “a>1.2.3>b>c” is part of the dependency graph of package “a” at version “1.2.3”, and has the local name “c”. It may or may not be the same as a package with the global name “c”.

Whether this node represents a direct or indirect dependency within this dependency graph. Note that it’s possible for a dependency to be both direct and indirect; if so, it is marked as direct.

Can be one of SELF, DIRECT, INDIRECT.

nodes[].errors[]: string[]

Errors associated with this node of the graph, such as an unresolved dependency requirement. An error on a node may imply the graph as a whole is incorrect. These error messages have no defined format and are intended for human consumption.

The edges of the dependency graph.

edges[].fromNode: number

The node declaring the dependency, specified as an index into the list of nodes.

edges[].toNode: number

The node resolving the dependency, specified as an index into the list of nodes.

The requirement resolved by this edge, as declared by the “from” node. The meaning of this field is system-specific. As an example, in npm, the requirement “^1.0.0” may be resolved by the version “1.2.3”.

error: string

Any error associated with the dependency graph that is not specific to a node. An error here may imply the graph as a whole is incorrect. This error message has no defined format and is intended for human consumption.

GetDependents
