CEU - Data Engineering 4 - AI Engineering - Preparations

Hi, in order to spend our time as usefully as possible, I'd like to ask you to sign up for these services by the end of the day Friday:

AWS

We'll use AWS to generate your credentials and access the Amazon Bedrock LLMs

Your AWS user has been reset. Please log back in using the default password:

AWS will ask you to change your password once you log in. Please take note of your new password

Once you've logged in, click Security Credentials in your Profile (top-right corner) Create Access Key (use case: Other, no tags required) and save your Access Key and Secret access key.
AWS Access Key

OpenAI API We'll use OpenAI for Model Tracing - a debug interface about how Agents work

  1. Go to https://auth.openai.com/log-in
  2. Click Sign Up Once you log in:
  3. Organization name: Personal
  4. What best describes you: Student
  5. "I'll invite my team later."
  6. API key:
    • Key name: CEU
    • Project name: leave Default Project
    1. "Generate API key" -> copy and save your key

Render.com

We'll need this for deploying agents to production URL: https://dashboard.render.com/register Use the GitHub signup option - this way, Render will have access to your GitHub repositories automatically.

EXA Search

We'll use EXA's Agentic MCP endpoint to let agents do a web search

  • URL: https://exa.ai
  • "Try API for free": EXA Sign Up
  • You'll probably need to use a gmail address to sign up (at least I only succeeded with "Google Login")
  • Select these: EXA Options
  • Choose "Compact"
  • Copy and save your EXA API key. We'll need it in class.

Definition of Done

You have all of these at hand:

  • An AWS Access key and Secret Access Key
  • An OpenAI API key
  • An EXA API key
  • Render.com registration using your GitHub Account

Thank you, and I am looking forward to seeing you on Monday! Zoltan
