# Serpex review (2026): is it worth paying for? > Pay-as-you-go web search and page extraction API for AI agents Checked Oct 23, 2026 ยท graded Oct 23, 2026 by ToolGPA. Serpex is a web search API built for AI agents and LLM apps. A search returns ranked results with titles, URLs and snippets, and can also fetch the pages behind the top five or ten as clean markdown in the same call; a separate Extract endpoint pulls content from any URL.

Serpex is a pay-as-you-go web search API for AI agents that can return the pages behind the top results as markdown, from a $5 top-up that never expires. Each query goes to whichever source is up, and you can't pick the engine, country or device, so it can't tell you what ranks on Google anywhere. - **Value for money: A.** $5 is the smallest top-up, under 60% of this category's cheaper quarter, and buys 6,250 credits at $0.80 per 1,000; $50 gets $0.65. Credits never expire. - **Free plan and trial: C.** No free plan: 200 credits for new accounts with no card. - **Features: D.** Web search with site and date operators, the top 5 or 10 pages returned as markdown, and an Extract endpoint. For SEO it misses the core: you can't choose the engine, country or device, so it reports no Google rankings for any place. - **Ease of use: C.** Judged on how fast a developer gets a first result: TypeScript and Python SDKs, a playground and usage analytics in the dashboard. No rating on record. - **Platforms and integrations: B.** Web, with an API, TypeScript and Python SDKs, an MCP server and LangChain examples. No desktop or phone app, so B is the top.

The category's chart of price against score: https://toolgpa.com/charts/seo-data-apis ## Keep it, or make your own? **Keep it.** To replace Serpex you would be making search results fetched at scale from many countries without being blocked. That is not a weekend's work, with an AI app builder or without one. - You could not: Search results fetched at scale from many countries without being blocked. - You could not: It plugs into other products, LangChain and MCP among them, and has an API. - You could not: AI features, unless you pay a model provider for each request yourself.
