Example prompt: Find me small or emerging pharma and device manufacturers from CMS Open Payments that first appeared in 2021 or later, pay cardiologists, are active in Texas, and have a total spend under $100,000 — sort by first seen year ascending.

## When to prefer this

Use this endpoint when you need to discover pharmaceutical or medical device manufacturers in CMS Open Payments by name, spend size, or recency of entry — especially to identify small, emerging, or niche brands engaging physicians in a specific specialty or geography. Prefer this over the sibling 'which manufacturers pay a given physician specialty' endpoint when the primary question is about the manufacturer dimension itself (who are the companies?) rather than spend aggregates by specialty. Best for compliance research, competitive landscape mapping, and territory analysis involving new market entrants.

## Known failure modes

- No manufacturers match the combined filters — returns empty result set
- Specialty string doesn't match Open Payments leaf taxonomy exactly — returns empty or unexpected results
- State code not recognized — may return error or empty results
- max_total_spend set too low — filters out all records
- first_seen_year_min/max range excludes all data — empty response
- Offset exceeds total results — returns empty page
- Invalid sort field value — may return error

## How this service works

Discover pharma & device MANUFACTURERS from CMS Open Payments by name, total-spend band, or year of first appearance — the emerging/small-brand filter (low total_spend and/or recent first_seen_year) plus optional specialty/state activity. Answers: which small or new manufacturers pay physicians in my category and territory? Entity-resolved company dimension (DBA/subsidiary variants merged). Filter: name, max_total_spend, first_seen_year_min/max, specialty, state.

## Output

Returns a paginated list of entity-resolved manufacturer records from CMS Open Payments, each including the canonical display name (with DBA/subsidiary variants merged), total all-time reported spend, year first seen in the program, count of physician engagements, and number of distinct specialties paid. Results can be sorted by spend, first seen year, engagements, or specialties.
