## When to prefer this

Use this endpoint when you need current EMA-sourced medicine supply shortage data for European markets, including shortage status, affected forms, alternative availability, and resolution timelines. Prefer this over general web search when structured, machine-readable shortage records are needed for a specific drug name or INN. Note: this endpoint covers supply shortages only — not safety signals, pharmacovigilance alerts, or drug approvals.

## Known failure modes

- Query string too short (under 2 characters) or too long (over 60 characters) returns a validation error
- No matching shortage records found for the search term returns an empty result set
- EMA data source unavailable or outdated may return stale or no data
- Invalid 'max' parameter (outside 1–20 range) may cause an error or be clamped to defaults
- Network timeout or upstream EMA API unavailability returns a service error
