# Set Up TypingMind with Alter API

> Connect TypingMind to Alter API Router using OpenAI Chat Completions format

Use this guide to add Alter as a custom provider in TypingMind.

## Open Custom Model Setup

In TypingMind, go to:

`Settings` -> `Models` -> `+ Add Custom Model`

## 1) Basic Configuration

Set the fields as follows:

* `Name`: `Alter`
* `API Type`: `OpenAI Chat Completions API`
* `Endpoint URL`: `https://alterhq.com/api/v1/chat/completions`
* `Model ID`: choose one from the supported IDs below
* `Context Length`: default value, or any value you prefer

## 2) Authentication

In the Authentication section:

* `Authentication Type`: `No authentication`

Note: We will pass the API key manually via Custom Headers in the next step.

## 3) Advanced Configuration (Required)

Expand `Advanced` at the bottom, then add a Custom Header pair:

* `Key` (left): `Authorization`
* `Value` (right): `Bearer <YOUR_API_KEY>`

Replace `<YOUR_API_KEY>` with your real Alter API key.
Make sure there is one space between `Bearer` and your key.
