SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires requests, and includes scripts (resource) components.

What problem does it solve?

This skill provides real-time access to current scholarly research and high-quality citations using Perplexity's Sonar models via OpenRouter. It helps researchers and writers verify claims, gather literature, and assemble citations quickly.

Core Features & Use Cases

  • Real-time academic literature search focused on peer-reviewed sources
  • Automatic model selection between Sonar Pro Search and Sonar Reasoning Pro based on query complexity
  • Comprehensive citations including DOIs, URLs, and source metadata
  • Batch queries and CLI/Claude Code integrations for writing workflows
  • Outputs structured results with sources, timestamps, and usage info for reproducible work

Quick Start

  • Ensure OPENROUTER_API_KEY is set: export OPENROUTER_API_KEY="your_api_key"
  • Run a simple lookup: python lookup.py "Recent advances in CRISPR gene editing 2024"
  • Run a batch lookup: python research_lookup.py --batch "CRISPR advances" "quantum computing review 2023"
