1. Four Production Bottlenecks of Google Custom Search JSON API
Teams building AI search assistants or SEO rank monitors on customsearch/v1 hit four structural limits as soon as traffic scales.
| Dimension | SearchData API (/v1/search) | Google Custom Search JSON API |
|---|---|---|
| Price per 1,000 Queries | $0.08 – $0.20 / 1K | $5.00 / 1K (25x–62x costlier) |
| Daily Quota Ceiling | Unlimited (up to 600+ RPM) | Hard 10,000 queries / day cap |
| SERP Fidelity | True Google.com Organic Rankings | Filtered Programmable Search subset |
| People Also Ask & Related | Included in every response | Not returned |
| Results per Request | Up to 100 results | Max 10 results per page |
2. Field-by-Field Migration from customsearch/v1
Drop GCP API key + cx engine ID configuration and call GET /v1/search with a single sr_live_ key.
Drop-In Replacement for googleapis.com/customsearch/v1
Fetch authentic Google organic rankings + PAA at $0.20/1K base ($0.08/1K Scale).

Frequently Asked Questions
- Do I need a Google Cloud project or Programmable Search Engine ID (cx)?
- No. SearchData API manages all upstream Google SERP routing directly — you only pass your sr_live_ key, query q, country, and lang.
- Can I request more than 10 results per call?
- Yes. Pass limit up to 100 on GET /v1/search, whereas Google Custom Search caps num at 10 per call.
