Just start using any skill! Claude will automatically:
~/.valyu/config.jsonYou: Search PubMed for CRISPR advances in 2024
Claude: "To search PubMed, I need your Valyu API key from https://platform.valyu.ai"
You: val_abc123...
Claude: [saves key and runs search automatically]
If you prefer to set up manually:
Environment Variable (recommended):
# For Zsh (macOS default)
echo 'export VALYU_API_KEY="your-api-key-here"' >> ~/.zshrc
source ~/.zshrc
# For Bash
echo 'export VALYU_API_KEY="your-api-key-here"' >> ~/.bashrc
source ~/.bashrc
Config File:
mkdir -p ~/.valyu
echo '{"apiKey": "your-api-key-here"}' > ~/.valyu/config.json
