NVD API Client
=================
NVD API client is a community driven NVD API 2.0 client.
This client support `Vulnerabilities`_ API and `Products`_ API.

Getting Start
=============
Products / CPE API
---------------------
This API's simple example is bellow.
.. code-block:: python
from client import NvdApiClient
from pprint import pprint
client = NvdApiClient()
response = client.get_cpes(
cpe_name_id="87316812-5F2C-4286-94FE-CC98B9EAEF53",
results_per_page=1,
start_index=0
)
pprint(response)
`get_cpes` method check API's all constraints and limitations.
* cpeNameId and matchCriteriaId must be uuid format.
* cpeMatchString must be CPEv2.3 format.
* If filtering by keywordExactMatch, keywordSearch is REQUIRED.
* If filtering by the last modified date, both lastModStartDate and lastModEndDate are REQUIRED.
* resultsPerPage's maximum allowable limit is 10,000.
* The maximum allowable range when using any date range parameters is 120 consecutive days.
Products / Match Criteria API
-----------------------------
This API's simple example is bellow.
.. code-block:: python
from nvd_api import NvdApiClient
from pprint import pprint
client = NvdApiClient()
response = client.get_cpe_match(
cve_id="CVE-2022-32223",
results_per_page=1,
start_index=0
)
pprint(response)
`get_cpe_match` method check API's all constraints and limitations.
* cveId is must be CVE ID format.
* If filtering by the last modified date, both lastModStartDate and lastModEndDate are REQUIRED.
* matchCriteriaId must be uuid format.
* resultsPerPage's maximum allowable limit is 5,000.
* The maximum allowable range when using any date range parameters is 120 consecutive days.
* cpeName must be CPEv2.3 format.
Vulnerabilities / CVE API
---------------------------
This API's simple example is bellow.
.. code-block:: python
from nvd_api import NvdApiClient
from pprint import pprint
client = NvdApiClient()
response = client.get_cves(
cpe_name="cpe:2.3:o:debian:debian_linux:3.0:*:*:*:*:*:*:*",
cvss_v2_metrics="AV:L/AC:L/Au:N/C:C/I:C/A:C",
cvss_v2_severity="HIGH",
results_per_page=1,
start_index=1
)
pprint(response)
* cpeName must be CPEv2.3 format.
* cveId is must be CVE ID format.
* cvssV2Severity, cvssV2Metrics is must be CVSS v2 format.
* cvssV3Severity, cvssV3Metrics is must be CVSS v3 format.
* cweId is must be CWE ID format.
* resultsPerPage's maximum allowable limit is 2,000.
* If filtering by keywordExactMatch, keywordSearch is REQUIRED.
* If filtering by the last modified date, both lastModStartDate and lastModEndDate are REQUIRED.
* If filtering by the last modified date, both pubStartDate and pubEndDate are REQUIRED.
* The maximum allowable range when using any date range parameters is 120 consecutive days.
* cvssV2Metrics cannot be used in requests that include cvssV3Metrics.
* cvssV3Metrics cannot be used in requests that include cvssV2Metrics.
* cvssV2Severity cannot be used in requests that include cvssV3Severity.
* cvssV3Severity cannot be used in requests that include cvssV2Severity.
Vulnerabilities / CVE Change History API
-------------------------------------------
This API's simple example is bellow.
.. code-block:: python
from nvd_api import NvdApiClient
from pprint import pprint
client = NvdApiClient()
response = client.get_cve_history(
change_start_date="2021-08-04T00:00:00.000",
change_end_date="2021-10-23T00:00:00.000",
event_name="CVE Rejected",
results_per_page=1,
start_index=1
)
pprint(response)
`get_cve_history` method check API's all constraints and limitations.
* If filtering by the change date, both changeStartDate and changeEndDate are REQUIRED.
* cveId is must be CVE ID format.
* resultsPerPage's maximum allowable limit is 5,000.
* The maximum allowable range when using any date range parameters is 120 consecutive days.
With API Key
---------------------
If you have the nvd api key, you can set key to client.
.. code-block:: python
from nvd_api import NvdApiClient
from pprint import pprint
client = NvdApiClient(wait_time=1 * 1000, api_key='THIS IS API KEY')
response = client.get_cves(
cpe_name="cpe:2.3:o:debian:debian_linux:3.0:*:*:*:*:*:*:*",
cvss_v2_metrics="AV:L/AC:L/Au:N/C:C/I:C/A:C",
cvss_v2_severity="HIGH",
results_per_page=1,
start_index=1
)
pprint(response)
* api_key : api key published by nvd.
* wait_time : interval time to execute api (with api key is 50 requests in a rolling 30s window, without api key is 5 requests in a rolling 30s window)
