## How to call it through Zero

```sh
zero fetch --capability stratalize-housing-supply-benchmark-65a3d1a0
```

Example prompt: Pull the housing supply benchmark for the South region covering all structure types — I want starts, permits, completions, and absorption as a leading indicator for where prices are heading over the next 6-12 months.

## When to prefer this

Choose this endpoint when you need forward-looking housing supply data (starts, permits, completions, absorption) as a leading price indicator, especially when cryptographic verifiability of the data is required. Prefer over general real estate endpoints when the use case is supply-side pipeline analysis for lending decisions, development feasibility, or macroeconomic forecasting 6-12 months ahead.

## Known failure modes

- Invalid region enum value returns 400 bad request
- Invalid structure_type enum value returns 400 bad request
- FRED or Census data temporarily unavailable returns 503 or stale-data indicator
- Payment not processed (x402 protocol failure) returns 402 Payment Required
- Signature verification failure at trust.stratalize.com indicates data integrity issue
