Fetch your first agent¶

Step 1

Fetch the hello_world agent and get into the agent's project folder:

aea fetch fetchai/hello_world:0.1.4
cd hello_world

This agent simply prints Hello World! on the screen.

Install the agent's dependencies:

aea install

Create and add a private key¶

All AEAs need a private key to run.

Step 3

Generate and add a private key to the agent:

aea generate-key fetchai --add-key

Run the AEA¶
