Perplexity Agent API
#2 in Agent FrameworksPerplexity · 5× · last seen Jul 19, 2026
The Perplexity Agent API is a managed runtime for agentic workflows released by Perplexity in March 2026, bundling web search, tool execution, and multi-model orchestration through a single endpoint. It is model-agnostic and provides access to frontier models from OpenAI, Anthropic, Google, xAI, NVIDIA, and other providers at direct provider pricing with no markup. Developers can use predefined presets (including fast search or Deep Research) or integrate custom configurations with Custom Functions/Skills to connect agents to their own backends, databases, and APIs. Recently, the API added support for "Skills"—reusable, composable capability modules that combine built-in skills (such as Office/PDF) with custom-developed Skills.
