Example prompt: Search DailyMed for the current FDA Structured Product Labels for metformin — I need the label SET IDs, versions, and publication dates for the first 10 results.

## When to prefer this

Use this endpoint when you need to programmatically discover and reference current FDA-approved drug labeling documents from DailyMed, particularly when you need SET IDs for downstream label content retrieval, compliance workflows, or pharmacovigilance tasks. Prefer over scraping DailyMed directly when you need structured, machine-readable results at scale.

## Known failure modes

- No results returned if drug name, NDC, or labeler doesn't match any DailyMed record
- Invalid NDC format may return empty results or an error
- Page number out of range (1-20) may cause error or empty response
- Ambiguous drug name may return too many or irrelevant results
- Rate limit or payment failure may block the request
