Quick Start

Prerequisites

Before you begin, you'll need:

• An account with API access
• A workspace (created automatically on signup)
• cURL or any HTTP client

Create an API Key

Navigate to your workspace settings and create a new API key:

1. Go to Settings → API Keys
2. Click Create API Key
3. Give it a name (e.g., "Development")
4. Select the scopes you need (read, write, delete)
5. Copy the key — it won't be shown again!

Make Your First Request

Let's verify your API key by searching agent memories:

curl --request POST \
  --url 'https://api.lthn.ai/v1/brain/recall' \
  --header 'Authorization: Bearer hk_your_api_key' \
  --header 'Content-Type: application/json' \
  --data '{"query": "hello world"}'

You should receive a response like:

{
  "memories": [],
  "scores": {}
}

Store a Memory

Now let's store your first memory in the brain:

curl --request POST \
  --url 'https://api.lthn.ai/v1/brain/remember' \
  --header 'Authorization: Bearer hk_your_api_key' \
  --header 'Content-Type: application/json' \
  --data '{
    "content": "Go uses structural typing",
    "type": "fact",
    "tags": ["go", "typing"]
  }'

This stores a fact in the vector database. You can then recall it with a semantic query.
