# Exporting Software Bill of Materials on CycloneDX

A Software Bill of Materials (SBOM) is a detailed inventory of all software components, dependencies, and associated metadata within an application. The purpose of an SBOM is to provide clear visibility into these components, ensuring they meet security and compliance standards.

SBOMs can deliver the transparency that software users now demand by enabling a standard approach to understanding what is in an application and why.

Prisma Cloud supports exporting SBOM files in the CycloneDX v1.4 standard ([JSON](https://cyclonedx.org/docs/1.4/json/) or [XML](https://cyclonedx.org/docs/1.4/xml/)) for function, image, and host scans.

## SBOM Attributes

The SBOM files contain the following attributes.

| Attribute       | Description                                                                                                                                                                                   |

## Download format for SBOMs

SBOM files can be downloaded either through API calls or twistcli.

### Download SBOMs using twistcli tool

The following option in the `twistcli` tool enables you to download SBOMs for function, image, and host scans:

`--SBOM [file_format]`

The file format values are `cyclonedx_json` or `cyclonedx_xml`.

The SBOM output is concatenated with the scan results output. Use the `--output` flag to print the scan results and SBOM output to a specified file.

### Download SBOMs using REST APIs

The following API endpoints enable you to download SBOMs for function, image, and host scans:

* [Download SBOM Images API](https://pan.dev/prisma-cloud/api/cwpp/get-sbom-download-images/)
* [Download SBOM Hosts API](https://pan.dev/prisma-cloud/api/cwpp/get-sbom-download-hosts/)
* [Download SBOM VMs API](https://pan.dev/prisma-cloud/api/cwpp/get-sbom-download-vms/)
* [Download SBOM Serverless API](https://pan.dev/prisma-cloud/api/cwpp/get-sbom-download-serverless/)
* [Download SBOM Registry API](https://pan.dev/prisma-cloud/api/cwpp/get-sbom-download-registry/)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.prismacloud.io/admin-guide/33/vulnerability-management/exporting-sboms.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
