The Perplexity API platform is now a full-stack, model-agnostic API platform for building agents.

It replaces your model provider, search layer, and embeddings, built on the same infrastructure that powers Perplexity. Image
The Perplexity API platform consists of four APIs with one API key.

Agent API — orchestrate models for multi-step workflows
Search API — real-time web context
Embeddings API — retrieval at scale
Sandbox API — code execution for agents (coming soon)
Perplexity Agent API is a managed runtime for building agentic workflows with integrated search, tool execution, and multi-model orchestration.

Swap between the latest frontier models, configure curated presets, tool access, step limits, and token budgets, all from one endpoint. Image
Search API is SOTA on all industry benchmarks including SimpleQA and SEAL.

It gives developers direct access to the same index that powers Perplexity with 200B+ URLs, refreshed in real time.

Use it to call real-time information with citations inside your own apps and agents. Image
Two weeks ago, we released two new SOTA embedding models.

Our Embeddings API was specifically designed for large-scale, efficient retrieval.

pplx-embed-v1-4B leads MTEB retrieval, ConTEB, and our internal benchmarks against 30M+ documents. Read more:
Our Sandbox API will be available as a tool within Agent API, allowing the orchestration runtime to delegate to deterministic code execution.

Sandbox API makes the same execution environment we use internally available as a standalone service for developers. Image

Introducing Perplexity Computer.

Computer unifies every current AI capability into one system.

It can research, design, code, deploy, and manage any project end-to-end.
Perplexity Computer is massively multi-model.

Computer orchestrates models to run agents in parallel, leveraging Opus to match each task to the model best suited for it.

In total, Computer can route work across 19 different models.
Perplexity Computer is what a personal computer in 2026 should be.

It’s personal to you, remembers your past work, and is secure by default.

Hundreds of connectors, persistent memory, files, and web access, all built on top of Perplexity infrastructure.

Harvard and Perplexity researchers conducted the first large‑scale field study of how people use AI agents.

We analyzed hundreds of millions of anonymized user interactions in Comet to answer three questions: who’s using agents, how much, and what for.

perplexity.ai/hub/blog/how-p…
More than half of all agent activity focuses on cognitive work.

Agent use is dominated by Productivity & Workflow (36% of queries) and Learning & Research (21%).

Users rely on the assistant to think through something, synthesize findings, and take action on those learnings. Image
Most agent queries come from personal use (55%), followed by professional (30%) and educational (16%) contexts.

New users often start with low-stakes questions like travel or trivia. Over time, they shift to more complex topics like productivity, learning, and career advice. Image

Introducing Perplexity Search API

We've built a search index of billions of webpages to provide real-time, quality information from the web.

Now developers have access to the full power of our index, providing the most accurate results in milliseconds.

perplexity.ai/hub/blog/intro…Image
With Microsoft retiring the Bing Search APIs in August, legacy search engines have abandoned the developer community who need real-time access to information.

We're stepping in to provide a search API designed for the new retrieval paradigms introduced by frontier AI systems.
We built Perplexity Search API around three criteria:

1. Completeness + freshness + speed
2. Fine-grained content understanding
3. Hybrid retrieval and ranking.

The system processes ~200M daily queries using distributed crawling/indexing, multi-stage ranking, and dynamic parsing.
