The SERP API Buyer's Guide 2026: 6 Vendors Tested Across 10 Dimensions

Background

I've worked on SEO monitoring, AI agent RAG, and academic SERP scraping. Different scenarios need different APIs. I tested 6 major vendors (SerpBase, SerpApi, Serper.dev, DataForSEO, Bright Data, Oxylabs) across 10 dimensions.

10-Dimension Comparison

1. Price (per 1k calls)

Provider Entry Mid Enterprise
SerpBase $0.30 (Boost, 1 month) $0.40 (Growth) $0.30 (negotiated)
SerpApi $10 (5k) $8.3 (30k) $4-5 (negotiated)
Serper.dev $1 (50k) $0.75 (200k) $0.45 (1M)
DataForSEO $0.50 (100k) $0.25 (1M) quote
Bright Data $1-1.5 quote quote
Oxylabs $0.90-1 quote quote

2. Speed (us region, English SERP, P50)

Provider P50 Notes
Serper.dev 1.2s Fastest
SerpBase 1.4s Stable
SerpApi 1.5-2.0s Slower
DataForSEO 2-3s Live mode slow
Bright Data 2-4s Slow
