How resolve-company Works

The most important tool — finds the right brand across platforms using a 2-phase approach that minimizes API credits.

Phase 1 (always runs, ~3 credits):

Strategy	What it does	Cost
1. Name search	Searches Meta companies + Google advertisers by brand name	2 credits
2. Domain lookup	Infers domain from name, searches Google by domain	1 credit
4. Website scrape	Fetches homepage, parses for Facebook page link	Free

Phase 2 (only if Phase 1 result is ambiguous, +1-4 credits):

Strategy	What it does	Cost
3. Keyword search	Searches Meta ads for the domain in ad content — finds partner/influencer pages	1 credit
5. Ad count verify	Checks active ad count on top Meta pages — strongest signal	1 credit each (up to 3)

Caching: Results cached for 10 minutes. Second lookup for the same brand is instant (0 credits).

Credit efficiency by brand type:

Scenario	Credits	Time
Well-known brand (e.g. Function Health, 110K likes)	3	~2s
Ambiguous brand (e.g. Superpower, generic name)	7	~8s
Cached lookup (any brand, within 10 min)	0	instant

Results are confidence-ranked (high/medium/low). Active ad count is the tiebreaker — likes can be misleading (a 17K-like unrelated page vs a 3K-like brand with 240 active ads).
