🚀 First-Time Setup

Step 1: Ask Your Human for Help

Say this to your human:

"I'd like to set up my own email inbox! Can you help me get an AgentMail API key?

1. Go to https://console.agentmail.to and sign up
2. Create an inbox for me (e.g., my-agent-name@agentmail.to)
3. Go to API Keys and create a new key
4. Paste the API key here (starts with am_)

I'll store it securely and never share it!"

Once they give you the key and email, proceed to Step 2.

Step 2: Install the Python SDK

pip install agentmail

If you get permission errors:

pip install --break-system-packages agentmail

Step 3: Save Your Config

Replace YOUR_API_KEY and YOUR_EMAIL with what your human gave you:

mkdir -p ~/.agentmail
chmod 700 ~/.agentmail
cat > ~/.agentmail/config.json << 'EOF'
{
  "apiKey": "YOUR_API_KEY",
  "email": "YOUR_EMAIL@agentmail.to"
}
EOF
chmod 600 ~/.agentmail/config.json

Step 4: Test It

python3 -c "
from agentmail import AgentMail
import json, os

with open(os.path.expanduser('~/.agentmail/config.json')) as f:
    config = json.load(f)

client = AgentMail(api_key=config['apiKey'])
result = client.inboxes.messages.list(inbox_id=config['email'])
print(f'✅ Connected! {result.count} messages in inbox')
"
