+How to use OpenAPI documentation
+--------------------------------------
+
+The API documentation is available at https://public.vulnerablecode.io/api/docs/.
+To use the endpoints you need to authenticate with an API key. Request your API key
+from https://public.vulnerablecode.io/account/request_api_key/. Once you have
+your API key, click on the ``Authorize`` button on the top right of the page and enter
+your API key in the ``value`` field with ``Token`` prefix, so if your token is "1234567890abcdef"
+then you have to enter this: ``Token 1234567890abcdef``.

+.. _Package Vulnerabilities Query:
+
+Query for Package Vulnerabilities
+------------------------------------
+
+The package endpoint allows you to query vulnerabilities by package using a
+purl or purl fields.
+
+Sample python script::
+
+    import requests
+
+    # Query by purl
+    resp = requests.get(
+        "https://public.vulnerablecode.io/api/packages?purl=pkg:maven/log4j/log4j@1.2.27",
+        headers={"Authorization": "Token 123456789"},
+    ).json()
+
+    # Query by purl type, get all the vulnerable maven packages
+    resp = requests.get(
+        "https://public.vulnerablecode.io/api/packages?type=maven",
+        headers={"Authorization": "Token 123456789"},
+    ).json()
+
+The response will be a list of packages, these are packages
+that are affected by and/or that fix a vulnerability.
+
+
+.. _Package Bulk Search:
+
+Package Bulk Search
+---------------------
+
+
+The package bulk search endpoint allows you to search for purls in bulk. You can
+pass a list of purls in the request body and the endpoint will return a list of
+purls with vulnerabilities.
+
+
+You can pass a list of ``purls`` in the request body. Each package should be a
+valid purl string.
+
+You can also pass options like ``purl_only`` and ``plain_purl`` in the request.
+``purl_only`` will return only a list of vulnerable purls from the purls received in request.
+``plain_purl`` allows you to query the API using plain purls by removing qualifiers
+and subpath from the purl.
+
+The request body should be a JSON object with the following structure::
+
+    {
+        "purls": [
+            "pkg:pypi/flask@1.2.0",
+            "pkg:npm/express@1.0"
+        ],
+        "purl_only": false,
+        "plain_purl": false,
+    }

+CPE Bulk Search
+---------------------
+
+
+The CPE bulk search endpoint allows you to search for packages in bulk.
+You can pass a list of packages in the request body and the endpoint will
+return a list of vulnerabilities.
+
+
+You can pass a list of ``cpes`` in the request body. Each cpe should be a
+non empty string and a valid CPE.
+
+
+The request body should be a JSON object with the following structure::
+
+    {
+        "cpes": [
+            "cpe:2.3:a:apache:struts:2.3.1:*:*:*:*:*:*:*",
+            "cpe:2.3:a:apache:struts:2.3.2:*:*:*:*:*:*:*"
+        ]

+
+The response will be a list of vulnerabilities that have the following CPEs.
