## When to prefer this

Choose this endpoint when you need Irish residential property sale price benchmarks by county with quarterly granularity. It is the right choice for budgeting, valuation comparison, or market trend analysis in Ireland. Prefer it over generic real estate APIs when you specifically need Irish CSO-style property register data with optional new vs second-hand segmentation and no API key requirement.

## Known failure modes

- Missing required 'county' query parameter returns an error
- Invalid or misspelled county name may return no results or an error
- Quarters value outside 1–12 range may be rejected or clamped
- Service unavailability due to Railway.app hosting downtime
- Payment failure via x402 protocol blocks access
