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:

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. Required parameters are passed as part of the request path, while optional parameters are passed as part of the query string.

All 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). This can be done using functions such as encodeURIComponent in JavaScript, url.PathEscape and url.QueryEscape in Go, or the equivalent in your programming language of choice.

For example, to get information about the npm package @colors/colors:

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

Note that the @ and / in the package name have been percent-encoded.

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:

curl -G \
  --data-urlencode 'hash.type=SHA1' \
  --data-urlencode 'hash.value=ulXBPXrC/UTfnMgHRFVxmjPzdbk=' \
  'https://api.deps.dev/v3alpha/query'

Note that we use the --data-urlencode flag as a convenient way to construct a query string with percent-encoded values.

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

Package names

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

Exceptions:

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:

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

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

nodes[].versionKey.name: string
