Challenge

Voice-Enabled Affordability Stress-Test Agent

Design an autonomous 'Market Advisor' agent using the OpenAI Agents SDK that performs affordability stress tests for different metros. The agent will analyze Zillow Observed Rent Index (ZORI), Zillow Home Value Index (ZHVI), and Redfin market temperature data (like inventory and price drops). You will integrate ElevenLabs to provide a high-quality, conversational voice interface that allows users to ask questions like 'How much would a 2% interest rate hike impact affordability in Austin?' The agent must identify rental-market anomalies where rent growth exceeds income growth or price drops are spiking unusually. By combining OpenAI's function-calling capabilities with real-world real estate metrics, the agent will simulate 'stress scenarios' (e.g., rising mortgage rates or unemployment) and communicate the impact via natural, synthesized speech. You will focus on building robust tools that fetch CSV data from Zillow and Redfin and calculate the housing cost burden for local residents.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

ElevenLabs Integration

Verifies that the agent successfully sends text to ElevenLabs and receives an audio response.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

Anomaly Detection Precision

Precision of the agent in identifying rental markets with >2 standard deviation growth. • target: 0.9 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

What you should walk away with

  • Master the OpenAI Agents SDK for defining autonomous agents with specialized tool-calling logic

  • Implement ElevenLabs 'Conversational AI' or 'Text-to-Speech' endpoints to create an interactive voice UI

  • Design data pipelines to parse and aggregate large Redfin 'Data Center' CSV files containing inventory and price drop metrics

  • Apply statistical anomaly detection (e.g., Z-score or Isolation Forest) to Zillow rental data across different geographies

  • Build a mortgage payment calculator function that the agent can use to simulate affordability scenarios

  • Optimize agent prompts for 'expert advisor' persona while ensuring data-driven accuracy

How this agent runs

Evaluation is based on the agent's ability to accurately calculate housing cost burdens and the successful integration of the voice interface.
