Serper vs Serpex (2026): which should you pick?

Pick Serper if

• Fits if you only need Google and would rather pay per query than per month
• Works for AI agents on LangChain or CrewAI that need current Google results

Look elsewhere if

• Skip it if you need Bing, Yahoo or any engine other than Google
• Watch out: credits expire 6 months after purchase, so a big pack you don't use up is money lost
• Tight if you're testing, as the 2,500 free queries come once and there's no monthly free plan
• Watch out: refunds run 7 days from the first payment, and only with under 20% of the credits used

Pick Serpex if

• Fits if you're building a RAG pipeline that needs the page text behind each result
• Works for uneven workloads, since prepaid credits never expire

Look elsewhere if

• Skip it if you need Google rankings, since you can't pick the engine, country or device
• Watch out: a search with page content costs up to 6 credits for 10 results, and Stealth Mode 5
• Watch out: every top-up is shown against a crossed-out price, such as $5 against $10
• Tight if you want a refund, which runs 7 days and only with no more than 20% of the credits used

Serper

• Its site lists Google endpoints only, with no Bing, Yahoo or other search engines.
• Credits expire 6 months after purchase, so a large pack bought for a lower rate can go unused.
• Refunds are given within 7 days of the first payment only if less than 20% of the credits are used.
• The 2,500 free queries are a one-time allowance, not a monthly free plan.

Serpex

• You cannot choose the search engine or set a country or device: every query is auto-routed, so it does not report what ranks on Google for a location.
• Search and extraction cost 1 credit each; a search with page content costs up to 6 credits for 10 results, and Stealth Mode 5 credits.
• Failed requests are free; refunds run 7 days on credit purchases with no more than 20% of the credits used.

Serper

Ten Google result types

Endpoints for Google web search, images, news, maps, places, videos, shopping, Scholar, patents and autocomplete.

Live results

Each call queries Google directly and nothing is cached; most results return in 1 to 2 seconds, sometimes 2 to 4 when a request is retried.

Location and language

Every pack lets you set the country and language a search is run from.

Rate limits by pack

From 50 queries a second on Starter to 300 on Ultimate, which Serper says is roughly 15,000 to 18,000 searches a minute.

Charged on success

Credits are deducted only for successful responses, and the API stops taking queries when the balance reaches zero.

AI framework integrations

Listed integrations with LangChain, CrewAI, Haystack and Jan AI for feeding search results to AI agents and chatbots.

Serpex

Web search API

Ranked results with title, URL, snippet and position, with site:, -site: and before:/after: date operators typed into the query.

Search with page content

Ask for the top 5 or 10 pages to be fetched and returned as markdown with the results, billed only for the pages delivered.

Extract API

Pull clean, readable content from any list of URLs at one credit per URL, cleaned up for vector databases and RAG pipelines.

Stealth Mode

Render JavaScript-heavy pages in a full browser on Extract requests, at five credits per successful request.

Automatic routing and retries

Every search goes to whichever source is healthy, with fallback to another source and retries if one is slow or down.

SDKs and MCP server

TypeScript and Python SDKs, an MCP server and LangChain examples, plus a playground and usage analytics in the dashboard.
