What is the cheapest SERP API in 2026?

ScrapingDog is the cheapest at volume at $0.29/1K queries. ValueSERP sits at $0.50/1K with batch processing for up to 15K requests per call. DataForSEO's standard tier is $0.60/1K but bundles 50+ other SEO APIs in the same account. Serper.dev at $1/1K is more expensive than the rock-bottom options but is the budget standard most AI teams adopt because of its 1–2 second response times and large user base.

Is there a free SERP API?

Not in the long-running sense. SerpApi offers 100 free queries per month indefinitely. Serper.dev, SearchAPI.io, ValueSERP, HasData, ScrapingDog, ScrapeOps, and Zenserp all run credit-based free trials – usually 1,000–5,000 queries that you burn through during evaluation. Treat free tiers as integration sandboxes, not as a production path. If you genuinely need zero-cost search, you are looking at running Searxng yourself or using an AI search API's free quota.

What's the difference between SerpApi and Serper.dev?

SerpApi has been around since 2017 and supports 80+ search engines including Bing, DuckDuckGo, Yahoo, Baidu, and Yandex on top of Google. Serper.dev is Google-only, cheaper ($1/1K vs $1.50/1K), and faster on response times. SerpApi is the answer when you need engine breadth or have an existing integration. Serper.dev is the answer when you need cheap, fast Google results for an AI workload. SerpApi is also the named defendant in Google's December 2025 DMCA suit, which factors into vendor risk for some buyers.

Should I use a SERP API or scrape Google myself?

For almost every AI product team, a SERP API is the right call. Self-scraping Google means maintaining residential proxies, solving CAPTCHAs, parsing a constantly mutating SERP layout, and absorbing the legal posture Google is currently sharpening with the SerpApi DMCA suit. The math only flips at very high volume (tens of millions of queries per month) and even then, most teams find the engineering cost dominates the per-query savings.

Which SERP API is best for AI agents?

Serper.dev is the most common pick for agent builders because of its low cost, simple JSON output, and fast response times. For agent stacks that prefer LLM-ready content over raw SERP HTML, an AI search API like Tavily or Brave Search API is usually a better fit. See our guide on [choosing a search API for AI](/guides/choosing-search-api-for-ai) for the SERP-vs-AI-search decision.

Cheap and Free SERP APIs in 2026: What Each Tier Actually Buys You

A SERP API is the cheapest line item on most AI product invoices, but the price spread inside the category is wider than people expect. The same Google search costs $0.29 per thousand queries on one provider and $1.50 per thousand on another. The difference isn't quality – it's engine coverage, response time, legal posture, and what the vendor bundles on top.

This guide walks the pricing landscape from the rock-bottom options up to the premium tiers, where each one fits, and what the "free" tiers actually give you.

The pricing landscape, ordered by sticker price

The market roughly sorts into four bands.

Rock-bottom. ScrapingDog at $0.29/1K queries at volume. Lowest price point in the entire SERP API category. India-based, focused on cost efficiency. The trade-off is support and uptime that don't match premium providers – fine for non-critical batch workloads, less ideal for production paths where occasional failures are expensive.

Budget bulk. DataForSEO at $0.60/1K standard tier and ValueSERP at $0.50/1K. Both are oriented toward higher-volume buyers. DataForSEO bundles 50+ other endpoints (keyword research, backlinks, on-page audits) in the same account, which is what makes its sticker price misleading – you're paying for a data platform, not just SERP. ValueSERP focuses on batch processing up to 15K requests per call, useful for SEO agencies running bulk audits.

Budget standard. Serper.dev at $1/1K queries. The default for AI startups: 1–2 second response times, simple JSON output, large active user base. It is Google-only with limited customization, but for most agent and RAG use cases that's exactly the surface needed.

Premium. SerpApi at $1.50/1K. Pioneer of the category, 80+ search engines, the most mature API surface. The premium buys you engine breadth (Bing, Yahoo, DuckDuckGo, Baidu, Yandex, etc.) and operational maturity. It also buys you vendor risk: SerpApi is the named defendant in Google's December 2025 DMCA suit and Reddit's parallel suit. SearchAPI.io sits near this tier as the legally-conservative alternative, advertising $2M legal protection backing.

Pricing comparison

Tool	Standard rate	Free / trial	Notable
ScrapingDog	$0.29/1K at volume	Credit-based trial	Cheapest at scale; thinner support SLAs
ValueSERP	$0.50/1K	Credit-based trial	Batch up to 15K requests per call
DataForSEO	$0.60/1K	Credit-based trial	Bundles 50+ SEO endpoints in one account
Serper.dev	$1/1K	Credit-based trial	1–2 second responses, AI-startup default
SerpApi	$1.50/1K	100 queries/month free, ongoing	80+ engines; active DMCA litigation
SearchAPI.io	Tiered freemium	Credit-based trial	$2M legal protection guarantee
HasData	Freemium	Credit-based trial	Fastest claimed response times
ScrapeOps	Freemium	Credit-based trial	Bundled with proxy aggregation + monitoring
Zenserp	Freemium	Credit-based trial	Image and reverse image SERP support

Numbers above reflect the public list price each vendor advertises at the time of writing. Negotiated enterprise rates run lower at every tier.

Free tier reality

Most "free SERP API" offers are credit-limited trials, not ongoing free quotas. Concretely:

SerpApi is the one provider with a genuinely ongoing free tier: 100 queries per month, indefinitely. Useful for prototypes and personal projects. Useless for anything user-facing at scale.
Serper.dev, SearchAPI.io, ValueSERP, HasData, ScrapingDog, ScrapeOps, Zenserp all ship credit-based free trials – usually 1,000 to 5,000 queries that you burn through during evaluation, then a card is required.
DataForSEO runs a small credit grant on signup; once it is consumed, the standard tier kicks in.

For genuinely free search at scale, you are looking at self-hosting Searxng (a metasearch aggregator with no usage fees but operational overhead) or piggybacking on an AI search API's free quota – both of which we cover in our getting started with AI search APIs guide. Treat the SERP API free tiers as integration sandboxes for evaluation, not as a production path.

When to pay more

Cheap is the right answer until it isn't. Three patterns push teams up a tier.

Engine coverage beyond Google. Serper.dev, ScrapingDog, ValueSERP, and HasData are Google-focused. If you need Bing, DuckDuckGo, Yahoo, Baidu, Yandex, or Naver in the same API, SerpApi's 80+ engines is the path of least resistance. Building this yourself across providers means juggling auth schemes, rate limits, and parsing differences – not impossible but rarely worth the saved dollars.

SERP feature parsing depth. Modern Google SERPs include AI Overviews, featured snippets, knowledge panels, People Also Ask, local packs, shopping results, and a long tail of other modules. Cheap APIs return the basic 10 organic results reliably; richer modules are where parsing quality varies meaningfully. SerpApi and DataForSEO are the most consistent on edge-case modules. Serper.dev handles the common cases well. ScrapingDog parses fewer modules at lower fidelity.

Bundled SEO data. If your product needs SERP results plus keyword volume, backlinks, or on-page audits, DataForSEO replaces a multi-vendor stack. Buying SERP from Serper, keyword data from Ahrefs, and backlinks from Moz costs more than DataForSEO's combined platform pricing, and the integration overhead is real.

Legal posture and indemnification. Google's December 2025 DMCA suit against SerpApi and Reddit's parallel suit shifted the category's legal landscape. SearchAPI.io advertises $2M legal protection backing. DataForSEO operates from Estonia, runs its own infrastructure, and was not named in the suit. Brave Search API – an AI search API, not a SERP scraper – serves Google-equivalent results from an independent index with no scraping legal exposure. For enterprise buyers with procurement review, this is sometimes the single deciding factor.

Reliability SLA. All providers in the category are functionally up most of the time. The difference shows up in the long tail: regional Google variants, low-volume languages, sustained high-QPS bursts. Premium providers handle these more gracefully. Cheap providers do fine on the happy path.

Cheapest viable stack for AI agents

For an AI product builder running an agent or RAG pipeline that hits Google, the calibration most teams converge on:

Default: Serper.dev at $1/1K. Fast, simple, reliable enough, and the AI-startup standard for a reason.
Cost-sensitive batch jobs: ScrapingDog at $0.29/1K when you have non-real-time work where occasional failures are acceptable.
Need keyword data too: DataForSEO at $0.60/1K, on the strength of the bundled endpoints rather than the SERP price alone.
Need engine breadth or feature parsing depth: SerpApi, with the legal-risk caveat priced in.
Need legal indemnification: SearchAPI.io's $2M protection guarantee.

A common production pattern: route by query class. Send the bulk of cheap, low-stakes queries to Serper.dev or ScrapingDog. Route queries where SERP feature parsing matters (rank tracking, competitive intelligence, structured-snippet extraction) to SerpApi or DataForSEO. Cache aggressively on the application side – a query for "what is RAG" doesn't need a fresh SERP every hour.

For agent-specific architectures where the model decides when to search, the cost calculus often shifts toward AI search APIs (Tavily, Brave Search API, Exa) rather than SERP scrapers, because they collapse the search-and-fetch loop into a single call. The decision tree for that branch lives in our choosing a search API for AI guide.

A buying rule

The shortest version of the buying decision: pick by what bites first.

If raw per-query cost dominates everything, ScrapingDog wins.
If response time and developer ergonomics dominate, Serper.dev wins.
If you are bundling SERP with broader SEO data, DataForSEO wins.
If engine breadth dominates, SerpApi wins despite the legal cloud.
If procurement requires indemnification, SearchAPI.io wins.

The category is competitive enough that the wrong choice is rarely catastrophic – integration is a few hours at most, switching costs are low. Pick on the constraint that matters most for your stack and revisit when something visibly breaks.
