Serpex

Affordable real-time search API that returns structured JSON plus page content in a single call.

Search API returning structured JSON

Send a query and receive live web results as clean, structured JSON that is ready for parsing, ranking or feeding into a model.

Built-in content extraction

Convert any URL into clean, readable markdown in the same API key, removing boilerplate so retrieved text is directly usable for RAG and summarization.

Automatic source fallback

Requests are routed across multiple underlying search sources with health monitoring and automatic retries, so a single empty source does not break your pipeline.

Developer SDKs and integrations

Official libraries and snippets for Python, JavaScript, MCP and LangChain make it a few lines of code to add live search to an agent or app.
