FAQPage Schema
How do I get real-time web search results with source citations for a literature review?▼

Real-time web search results with source citations are obtained by querying Perplexity models via OpenRouter. This approach retrieves current scientific literature and domain-specific information beyond a model's knowledge cutoff, grounding responses with citation-backed sources.

Do I need an OpenRouter API key to access Perplexity models for web-grounded searches?▼

An OpenRouter API key is required to access Perplexity models for web-grounded searches. The setup integrates the LiteLLM library to route requests through OpenRouter, enabling multi-model access including sonar-pro and sonar-reasoning variants.

Can I use LiteLLM to integrate Perplexity web search into my research workflows?▼

LiteLLM is used to integrate Perplexity web search into research workflows by providing an easy setup for routing queries. It supports accessing multiple Perplexity models through a single OpenRouter key to retrieve current, web-grounded information.

What is the best way to retrieve current scientific literature beyond a model's knowledge cutoff?▼

The best way to retrieve current scientific literature beyond a model's knowledge cutoff is using web-grounded AI-powered searches. By applying Perplexity models through OpenRouter, users access real-time information and domain-specific web searches with citation-backed results.

Which Perplexity models are available through OpenRouter for domain-specific web searches?▼

Available Perplexity models through OpenRouter for domain-specific web searches include sonar-pro, sonar-pro-search, and sonar-reasoning. Multi-model access is supported via a single OpenRouter key to execute real-time, citation-backed literature retrieval.
