# Creating a DeepSeek API key

Flow agent replies can run on DeepSeek. To use it, create your own **DeepSeek API key** in the DeepSeek Platform, then add it to Mampu AI. The whole process takes about 10 minutes.

> **Keep your API key private.** Treat it like a password — anyone with your key can spend your DeepSeek balance. The full key is shown **only once**, so save it somewhere safe such as a password manager. In the screenshots below the key value has been hidden for security.

## Before you start

* A computer with an internet browser.
* An email address you can access — DeepSeek sends a verification code to it.

## Quick summary

1. Open the DeepSeek Platform and sign up (or log in).
2. Go to **API keys** in the left sidebar.
3. Click **Create new API key**, give it a name, and click **Create API key**.
4. Copy and save the key immediately — it is shown only once.
5. Add credit under **Top up** so the key can be used.
6. Paste the key into the **DeepSeek** card in **Settings > Integrations > AI Providers**.

## 1. Open the DeepSeek Platform

Go to [platform.deepseek.com/sign\_in](https://platform.deepseek.com/sign_in). If you do not have a DeepSeek account yet, click **Sign up**. If you already have one, skip to step 3 and log in.

## 2. Create your account

Fill in the registration form:

1. Enter your email address.
2. Create a password, then type the same password again in **Confirm password**.
3. Click **Send code**. DeepSeek emails you a verification code — check your inbox and spam folder, then type the code into the **Code** box.
4. Click **Sign up** to finish.

## 3. Log in

Enter your email address and password, then click **Log in**. You can also use **Log in with Google** if you prefer.

## 4. Open the API keys page

After logging in you land on the **Usage** page. In the left sidebar, click **API keys**.

## 5. Create a new key

Click **Create new API key** on the right of the page.

## 6. Name your key

A window asks for a name. Enter a name you will recognise later, such as your business name, then click **Create API key**.

## 7. Copy and save your key

The full key is shown **only once**. Click **Copy** and paste it somewhere safe straight away, then click **Done**. The key starts with `sk-` followed by a long string of letters and numbers.

If you lose the key, DeepSeek cannot show it again — delete it from the list and create a new one by repeating steps 5 to 7.

## 8. Confirm the key was created

Your new key now appears on the **API keys** page with part of it hidden by asterisks. That is normal — only a masked version is shown here.

## 9. Add credit to your DeepSeek account

A new DeepSeek account starts with a balance of $0.00, and the API only works when there is credit in the account. Click **Top up** in the left sidebar and follow the payment steps. A small amount is enough to start.

## Add the key to Mampu AI

**1.** In Mampu AI, go to **Settings > Integrations > AI Providers**.
**2.** Find the **DeepSeek** card under **Flow agent replies**.
**3.** Paste the copied key and connect — the card shows **Connected** when the key is accepted.

Flow agents reply with the provider that has a key connected. If both Anthropic and DeepSeek are connected, DeepSeek is used; remove the DeepSeek key to switch back to Claude.

## Troubleshooting

* If replies stop working, check that your DeepSeek account still has credit.
* If the key is rejected, confirm you pasted the full value, starting with `sk-`.
* If your key is exposed or shared by mistake, delete it on the DeepSeek **API keys** page, create a new one, and update it in Mampu AI.
