# Get started with Cortex AgentiX APIs

Using the Cortex AgentiX APIs, you can integrate [Cortex AgentiX](https://cortex-docs.paloaltonetworks.com/cortex-agentix-docs/) with third-party apps or services to automate workflows and manage your AgentiX resources programmatically. The APIs let you build integrations that extend and orchestrate Cortex AgentiX across your security operations.

Before you can begin using Cortex AgentiX APIs, you must generate the following items in Cortex AgentiX:

| Value          | Description                                                                                                                                                                                                                                      |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **API Key**    | The API Key is your unique identifier used as the `Authorization:{key}` header required for authenticating API calls. Depending on your desired security level, you can generate two types of API keys, Advanced or Standard, from Cortex XSIAM. |
| **API Key ID** | The API Key ID is your unique token used to authenticate the API Key. The header used when running an API call is `x-xdr-auth-id:{key_id}`.                                                                                                      |
| **FQDN**       | The FQDN is a unique host and domain name associated with each tenant.                                                                                                                                                                           |

Cortex AgentiX API URIs are made up of your tenant's FQDN, the API name, and endpoint path. For example, `https://api-{fqdn}/agentix/public/v1/{endpoint_path}/.`

The following steps describe how to generate the necessary key values and run your first API call:

1. [Create a new API key](/agentix-api/readme.md).
2. [Get your Cortex XSIAM API key ID](/agentix-api/get-your-cortex-api-key-id.md).
3. [Get your FQDN](/agentix-api/get-your-fqdn.md).
4. [Make your first API call](/agentix-api/make-your-first-api-call.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://cortex-docs.paloaltonetworks.com/agentix-api/get-started-with-cortex-apis.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.
