Perplexity has introduced pplx, a command line interface that connects users to its Search API. The tool allows users to execute specific commands and receive JSON output. The pplx client is available as a single binary for macOS and Linux, along with an Agent Skill for various coding tools. This development provides developers with a direct interface to Perplexity's search capabilities. It matters because this access can streamline coding workflows and enhance productivity for users of Perplexity's Search API.
