## How this service works

AI-synthesized US housing market briefing. Fetches 8 FRED signals (starts, permits, existing/new sales, months supply, 30Y mortgage rate, Case-Shiller HPI, median price) and uses gpt-4o-mini to produce market phase, direction, supply posture, affordability regime, 150-word narrative, dominant risk, and agent implication. One call collapses 8 FRED lookups + LLM synthesis for REIT analysis, mortgage exposure, consumer wealth, and macro housing drag.

## Output

A structured housing market brief containing summarized intelligence on real estate conditions, pricing trends, and market dynamics for the queried area or segment, delivered as a data payload after micropayment via x402.
