SERP API Comparison: Zenserp, Scale SERP, and SearchCans Value Analysis

Detailed comparison of Zenserp, Scale SERP, and SearchCans. Compare pricing, features, and value to find the best SERP API for your development needs in 2026.

5 min read

If you are shopping for a Google Search API, you have likely come across Zenserp and Scale SERP. They are solid mid-market options, often positioning themselves as cheaper alternatives to SerpApi.

But in 2026, a new standard for affordability has emerged.

In this review, we compare SearchCans against these incumbents to see who truly offers the best value for developers and startups.

1. Zenserp: The “Enterprise Lite” Option

Zenserp positions itself on reliability and uptime. They offer features like “Location-based search” and “Image search”.

Pricing:

  • Their “Small” plan starts around $29.99/month for 5,000 searches.

Cost per 1k

Approximately $6.00.

The Catch

Like many legacy providers, they use a monthly subscription model. If you have a slow month, your unused credits disappear.

Pros:

  • Reliable uptime
  • Good documentation
  • Multiple search engines

Cons:

  • High cost per request
  • Subscription lock-in
  • Credits expire

2. Scale SERP: The Budget Incumbent

Scale SERP has long been a go-to for budget-conscious devs. They focus on infrastructure scalability.

Pricing:

  • Generally cheaper than Zenserp, often starting at $5-10/month for small volumes.

The Catch

Rate limits on lower tiers can be restrictive for AI applications that need burst concurrency.

Pros:

  • Lower entry price
  • Decent performance
  • Pay-as-you-go options

Cons:

  • Rate limits on budget tiers
  • Limited support
  • Less comprehensive documentation

3. SearchCans: The 2026 Disruptor ($0.56/1k)

SearchCans was built to solve the “subscription fatigue” problem. We realized that for AI Agents and RAG applications, developers need massive volume without the massive monthly commitment.

Pricing:

  • $0.56 per 1,000 searches. Period.

The Difference

That is 10x cheaper than Zenserp’s entry tier.

No Expiration

Our credits never expire. Buy them once, use them forever.

Features:

  • Unlimited concurrent requests
  • Google & Bing support
  • Real-time results
  • JSON response format
  • Global location targeting
  • No monthly commitments
