- Returns only ranked SERP results — no coverage-first enumeration of events outside the top search positions
- Free tier of 250 searches/month is insufficient to validate a production pipeline before committing to a paid plan
Zenserp
+ 100 free searches/month without a credit card — accessible for solo developers evaluating a Google SERP API
+ Transparent, publicly-listed pricing — no sales engagement required to understand cost at any volume
+ Single HTTP GET request to integrate — lowest onboarding overhead of any SERP API reviewed
+ Real-time results with geolocation and language targeting at no additional parameter cost
- Google-only — no Bing, Yahoo, or e-commerce engine support
