For an engineer or SEO tool founder, the useful comparison is the bill for a completed search workload. Separate the unit price, the amount paid upfront and the data your product actually needs.
Figures reflect the October 24, 2026 pricing snapshot from SerpApi's monthly price list and Serper's prepaid packs. WebScrap competes with both. Our SerpApi alternative comparison covers search jobs that also need page fetching.
The two price lists side by side
All prices are USD. SerpApi renews monthly and allows cancellation any time. Serper sells prepaid credits with sales tax excluded. Unit rates assume full use of the included capacity; a standard Serper query consumes one credit.
| Provider and plan | Price USD | Searches or credits | USD per 1,000 | Throughput |
|---|---|---|---|---|
| SerpApi Free | 0 monthly | 250 | 0 | 50/hour |
| SerpApi Starter | 25 monthly | 1,000 | 25.00 | 200/hour |
| SerpApi Developer | 75 monthly | 5,000 | 15.00 | 1,000/hour |
| SerpApi Production | 150 monthly | 15,000 | 10.00 | 3,000/hour |
| SerpApi Big Data | 275 monthly | 30,000 | 9.17 | 6,000/hour |
| SerpApi Searcher | 725 monthly | 100,000 | 7.25 | 20,000/hour |
| SerpApi Volume | 1,475 monthly | 250,000 | 5.90 | 50,000/hour |
| SerpApi Infrastructure | 2,750 monthly | 500,000 | 5.50 | 100,000/hour |
| SerpApi Cloud 1M | 3,750 monthly | 1,000,000 | 3.75 | 110,000/hour |
| SerpApi Cloud 2M | 5,675 monthly | 2,000,000 | 2.84 | See provider |
| SerpApi Cloud 50M | 98,325 monthly | 50,000,000 | About 1.97 | See provider |
| Serper Starter | 50 prepaid | 50,000 | 1.00 | 50 queries/second |
| Serper Standard | 375 prepaid | 500,000 | 0.75 | 100 queries/second |
| Serper Scale | 1,250 prepaid | 2,500,000 | 0.50 | 200 queries/second |
| Serper Ultimate | 3,750 prepaid | 12,500,000 | 0.30 | 300 queries/second |
SerpApi's larger monthly plans continue beyond Cloud 1M, so 3.75 USD is not its lowest rate. The SerpApi cost per 1,000 searches breakdown provides context. Serper also offers 2,500 trial queries once, with no card required.
Price per 1,000 searches at matched budgets
The closest tiers do not always have matching checkout prices. Compare capacity and unit rates while keeping the actual purchase amount visible.
| Budget USD | SerpApi | Serper |
|---|---|---|
| 50 | Starter 25 USD, 1,000 searches at 25.00 per 1,000 | Starter 50 USD, 50,000 at 1.00 per 1,000 |
| About 275 to 375 | Big Data 275 USD, 30,000 at 9.17 per 1,000 | Standard 375 USD, 500,000 at 0.75 per 1,000 |
| About 1,250 | Searcher 725 USD, 100,000 at 7.25 per 1,000 | Scale 1,250 USD, 2,500,000 at 0.50 per 1,000 |
| 3,750 | Cloud 1M, 1,000,000 at 3.75 per 1,000 | Ultimate, 12,500,000 at 0.30 per 1,000 |
A budget near 50 USD puts SerpApi between plans offering 1,000 and 5,000 searches. Only Starter fits a strict ceiling; Developer costs 75 USD, so its capacity cannot be bought as a partial plan. Near 1,250 USD, Searcher fits while Volume at 1,475 USD exceeds the budget.
For a founder setting a product budget, record both the checkout payment and the cost assigned to consumed searches. A prepaid balance can fund future work, but it still uses cash now. A monthly plan can leave capacity unused at renewal. The lowest published rate only helps when actual usage supports the purchase.
What each search buys
SerpApi covers Google plus Bing, Baidu, Yandex, Yahoo, DuckDuckGo and YouTube, with parsed Google verticals including Maps, Shopping, Scholar and Jobs. Paid plans include the US Legal Shield. Those capabilities can justify the premium when your product needs more than Google web results.
Serper focuses on fast Google results data, including web, images, news, maps, places, shopping and similar Google endpoints. It is a strong fit for a Google only product. Test the returned fields against your own queries before choosing either provider; a cheap response still needs to satisfy your schema.
Build that check around the screens your users will see. A rank report needs consistent query and location settings, while a research tool may need a specific vertical. Compare the output your application consumes rather than treating every search response as interchangeable. Engine coverage matters only when the workload calls for it.
Prepaid credits expire and monthly quotas reset
Serper credits remain valid for 6 months. The advertised unit price assumes you use them before expiry. Buying a bigger pack to obtain a lower rate only helps if your queue consumes the balance in time.
SerpApi's quota resets monthly. Its hourly allowance is about 20 percent of monthly capacity on many smaller tiers, although Cloud 1M has its own listed limit. Check both columns before scheduling a batch. Serper's queries per second and SerpApi's searches per hour describe throughput, not measured response latency.
SerpApi counts only successful searches. Cached, errored and failed searches do not consume quota. Keep billing rules separate from your application's validation of the returned data.
Schedule also affects the choice. A recurring tracker has a clearer consumption forecast than a lead discovery project that pauses between campaigns. For the tracker, compare the monthly quota with the reporting calendar. For the project, check whether the prepaid balance will survive the expected pauses without reaching its expiry date.
Rank tracking and lead lists priced both ways
Count result pages across keywords, locations and repeat checks for a tracker. For a lead list, count discovery searches separately from visits to company websites. These are modeled search volumes, not customer results.
| Monthly search workload | SerpApi bill | Serper purchase |
|---|---|---|
| Rank checks using 30,000 searches | Big Data 275 USD | Starter 50 USD, 30,000 credits used |
| Lead discovery using 500,000 searches | Infrastructure 2,750 USD | Standard 375 USD per month |
| Either workload using 1,000,000 searches | Cloud 1M 3,750 USD | 750 USD for two Standard packs, or Scale allocation of 500 USD |
At 30,000 searches, Serper's Starter pack lasts the month with credits left. At a million monthly, Scale allocates about 500 USD to the searches consumed, but requires 1,250 USD upfront for 2,500,000 credits. Use the balance within 6 months to realize that rate.
Our rank tracking API guide helps scope result page workloads. Teams handing reporting and content work to an SEO agency for SaaS should agree on search depth and reporting scope before pricing the underlying data.
A lead discovery response gives you search data, not the contents of every linked website. If qualification depends on reading those sites, budget that work separately from discovery. This distinction also matters for rank tracking tools that open competing pages to explain a ranking change or prepare a content recommendation.
Where a flat rate web scraping API fits
Search often starts a job that continues on the result pages. WebScrap's Google and Bing SERP JSON API returns organic results, ads, featured snippet, people also ask and local pack data, by country and US city. One Google results page uses one request.
| WebScrap plan | Monthly USD | Successful requests | USD per 1,000 |
|---|---|---|---|
| Starter | 49 | 50,000 | 0.98 |
| Growth | 149 | 250,000 | 0.60 |
| Scale | 499 | 1,500,000 | 0.33 |
The same plan fetches result pages and protected sites with rotating proxies and rendering. Blocked or failed requests are never billed. Count each successful page fetch as well as each search against the WebScrap plan allowance.
Serper costs about the same at 50,000 searches and less per search on its 12,500,000 credit pack. WebScrap fits jobs needing Google plus the pages behind it on one bill. The SerpApi alternative guide for mixed workloads explains that fit.
Which provider earns your budget
Pick Serper for Google only search volume when prepaid spending and expiry fit your forecast. Pick SerpApi for non Google engines, Scholar, YouTube, the legal shield or monthly billing without a large credit purchase. Pick WebScrap when search and page fetching belong in the same job.
If DataForSEO is on your shortlist, the SerpApi vs DataForSEO pricing comparison prices its standard, priority and live modes. For an AI search shortlist, the Tavily search pricing breakdown adds another comparison. Start with required output, then price the capacity you will actually consume.
Before switching an existing integration, run representative queries through the proposed replacement and compare the fields your parser reads. Include the locations and result types your customers request. Then estimate the full search queue and any followup page fetches. That gives you a purchase decision tied to the product you are building.
Questions buyers ask
Is Serper cheaper than SerpApi?
Yes, Serper is cheaper per search at every listed volume. Its prepaid rates run from 1.00 to 0.30 USD per 1,000 standard queries. SerpApi costs more but offers broader engine coverage and monthly billing. Unused capacity and Serper credit expiry still affect the cost you realize.
How much does Serper cost per 1,000 searches?
Serper costs 1.00 USD on Starter, 0.75 on Standard, 0.50 on Scale and 0.30 on Ultimate per 1,000 standard queries. These rates require purchasing the corresponding prepaid pack and consuming its credits within 6 months. Prices exclude sales tax, so distinguish the quoted rate from checkout spending.
Do Serper credits expire?
Yes, Serper credits are valid for 6 months. Choose a pack your expected workload can consume within that period. A larger purchase lowers the advertised rate per query, but credits left unused at expiry increase your effective cost. Compare likely usage with the upfront payment before buying.
Which is better, SerpApi or Serper?
Serper is better for a Google only workload focused on search cost. SerpApi is better when you need other engines, Scholar, YouTube, the US Legal Shield or monthly billing. Compare required fields, throughput and billing commitment using representative queries before selecting the provider for your product.
Does SerpApi have a free plan?
Yes, SerpApi has a free plan with 250 searches per month and an allowance of 50 searches per hour. It can support an initial integration check, but budget ongoing workloads against paid capacity. Serper separately offers 2,500 trial queries once with no card required, rather than a monthly quota.
Does SerpApi charge for failed searches?
No, SerpApi counts only successful searches. Cached, errored and failed searches do not consume its search quota. Keep that billing definition separate from whether a response contains the fields your application needs. Track usable output alongside billed searches when comparing the cost of completing a workload.
