Cons	- No free ongoing tier — free trial is 14 days only, paid plans start at $49/mo with limited credits - Raw data may require preprocessing (duplicates, HTML artifacts, inconsistent formatting from web-scraped sources)	- Free tier is only 100 requests/month — very limited for production agent workloads, paid dataset subscriptions start at $6k/year - No official SDK — agents must use raw HTTP requests with dual-header auth (api_key + api_token)
