API keys for invoice AI pipeline are stored in backend/.env:

LLAMAPARSE_API_KEY — LlamaCloud/LlamaParse, Cost Effective mode (gpt4o_mode), 3 credits/page, 3,333 free/month
OPENROUTER_API_KEY — OpenRouter, primary model: google/gemini-2.0-flash-001 ($0.10/$0.40 per M tokens)

How to apply: Django settings.py loads via python-dotenv. Never hardcode keys in source files. OpenRouter uses OpenAI-compatible API at https://openrouter.ai/api/v1/chat/completions.
