Overview
Serpex.dev is a pay-as-you-go search API built for AI agents and data teams rather than human researchers.
A single endpoint routes each query across multiple search engines, handles blocking and CAPTCHAs, and returns clean JSON, so a script can pull live web results without maintaining its own proxy pool or scraper farm.
Alongside search it offers scraping and content extraction, plus a clean-and-structure stage that turns raw pages into text ready for a vector database or an LLM prompt.
The pitch is straightforward: search-API quality at a fraction of the cost of the best-known providers, with entry pricing advertised from about $0.0008 per request.
For marketers the practical value is automation rather than browsing.
Instead of checking rankings by hand, you wire Serpex into n8n, Make, Zapier, LangChain, or your own Python script and let it collect SERP snapshots, competitor pages, and brand mentions on a schedule.
SDKs ship for Python and JavaScript, and an MCP server covers teams building agent workflows.
It is developer-first, so a non-technical marketer will lean on the no-code integrations rather than the raw API.
Use Cases
Automating daily SERP snapshots for keyword rank tracking
Feeding live web search results into AI agents and RAG pipelines

Best fit is SEO and research engineers who already run pipelines; the trade-off is that there is no friendly visual UI and stealth extraction costs five credits per request. Spend the free credits first to benchmark result quality against your own query mix before committing to a pack.
