## When to prefer this

Use this endpoint when you need a reliable, authoritative national US rent inflation figure derived from BLS CPI data via FRED — ideal for macroeconomic analysis, investment research, or answering questions about rental cost trends at the national level. Prefer this over Zillow or local listing-based sources when you need an official government statistical measure of rent inflation rather than market-rate asking prices.

## Known failure modes

- FRED data temporarily unavailable — upstream data source outage
- Stale data if FRED has not yet published latest release
- Payment failure for x402 micropayment (insufficient USDC balance)
- Rate limiting or access errors if payment not processed correctly
