CatchAll

- Lite mode is capped at 100 results and lacks the full coverage depth of Base mode
- Smaller ecosystem and community compared to established providers like SerpAPI or Bing Search API
Webz.io
+ Dark web and paste site coverage via Cyber API — unique in this category for threat intelligence and OSINT workflows

+ Entity-level pre-filtering reduces downstream NLP processing needed to extract structured signals from raw text
+ Government and intelligence agency clients — proven in high-security and regulated environments (per company website; independently unverifiable)
- Pricing not publicly disclosed — requires enterprise sales contact before technical evaluation
- Not a SERP API — does not return search engine result pages; unsuitable for SEO rank tracking or Google result retrieval
- Dark web data may trigger additional procurement and legal review before production use in some organisations
