# Connecting LLM Service

You can connect **Sigrex** to popular **LLM providers** using your own API keys. Once connected, you’ll be able to interact with and switch between supported models directly from your assistant logic or trading tools.

## 🧠 Supported Providers

Sigrex supports all major LLM providers shown below:

Each connection lets you choose and use any available model, including those with **vision capabilities** for chart analysis.

## 🔐 Security & Key Management

All API keys are **securely encrypted** and only decrypted at runtime.\
Even platform operators cannot access your plain-text API keys.

## ⚙️ Connection Rules

* During setup, Sigrex sends a **test request** to validate your API key:
  * If the key is invalid or your account lacks credits, the connection will fail.
* The **API key cannot be edited** after creation.
* The **model** can be changed freely within the same provider connection.

## 🪄 Steps to Connect

1. Choose your preferred **LLM provider** from the list.
2. Select the **model** you want to use under that provider.
3. Insert you API key.
4. Click **“Create Connection.”**
5. If the test succeeds, the connection is saved and available to activate.

Once connected, you can freely switch between **supported models** (including vision-enabled ones) across your Sigrex tools — such as **trading bots**, **assistants**, and **dashboards**.

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://docs.sigrex.io/llm/connecting-llm-service.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.
