SPRINGER_TDM_API_KEY=your_springer_tdm_api_key
IOP_papers_path=local_path_to_iop_papers # IOP Publishing provides XML articles in bulk through SFTP access

# API Keys for LLM Models (at least one is required which will be used for data extraction)
OPENAI_API_KEY=your_openai_api_key
DEEPSEEK_API_KEY=your_deepseek_api_key
ANTHROPIC_API_KEY=your_anthropic_api_key
GEMINI_API_KEY=your_google_api_key
OPENROUTER_API_KEY=your_openrouter_api_key

# Hugging Face API Key (for accessing thellert/physbert_cased model for embeddings)
HF_TOKEN=your_huggingface_api_key

# Neo4j Configuration (for knowledge graph visualization)
NEO4J_URI=bolt://localhost:7687
NEO4J_USER=neo4j
NEO4J_PASSWORD=your_password
