industry.industry
The industry.industry filter expects akta.pro taxonomy industry codes, not free-text sector names like "warehouse automation" or "fintech". Resolve the topic first with the Industry Search API:
location.hq.country, location.market_served.markets, and location.offices.country all expect 3-letter ISO alpha-3 codes (USA, IND, GBR), not full country names ("United States"). Passing a name instead of a code will not match. location.hq.city by contrast, take free text. location.hq.region takes M49 region codes.
total_count after each addition to confirm you haven’t over-narrowed the list.
Check total_count before paginating
total_count tells you how many companies match your filters in total, capped at 500. Use it to decide whether to paginate with offset, or to tighten your filters if the match is too broad to be useful.
