claude \
  -u https://your-domain.com/v1 \
  -k "$LLM_PROXY_API_KEY"

Shell environment setup

bash

export OPENAI_API_BASE="https://your-domain.com/v1"
export OPENAI_API_KEY="$LLM_PROXY_API_KEY"

Then run: `claude --model claude-sonnet-4-20250514`

Troubleshooting

bash

# Invalid key / auth errors
# - verify OPENAI_API_KEY starts with lp_
# - verify key is ACTIVE in /dashboard/api-keys

# Model not found
# - call GET /v1/models and pick an available id

# Rate limit exceeded
# - reduce request volume or increase plan/key limits
