x402serps
Pay-per-call web search from $0.004, cited answers, crawl, research, SEO and leads via x402.
What it does
x402serps is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
From the publisher's description, Electra Index matched it to one capability: web research. That makes it a candidate for tasks such as find leads or fact-check a document.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.
