This one needs environment variables set before it will start: NCBI_API_KEY (Optional NCBI E-utilities API key; raises the rate limit 3->10 req/s for omics, literature, and taxonomy lookups.), LLM_API_BASE (Base URL of an OpenAI-compatible /chat/completions endpoint; enables search(understand=true) and search(multi_query=true).), LLM_API_KEY (Bearer token for the LLM endpoint (LLM_API_BASE); omit for keyless local servers.), LLM_MODEL (Model name passed to the LLM endpoint (default: gpt-4o-mini); set to whatever your endpoint serves.), EMBEDDING_API_BASE (Base URL of an OpenAI-compatible /embeddings endpoint; enables search(rank=semantic) re-ranking.), EMBEDDING_API_KEY (Bearer token for the embeddings endpoint (EMBEDDING_API_BASE); omit for keyless local servers.), EMBEDDING_MODEL (Model name passed to the embeddings endpoint (default: text-embedding-3-small).), DATA_GOV_API_KEY (Optional api.data.gov key for the data.gov source; without it requests fall back to the shared public DEMO_KEY, which is aggressively rate-limited.), UNPAYWALL_EMAIL (Email address sent to the Unpaywall API; required to enable the Unpaywall PDF fallback leg of literature full-text retrieval.), NCBI_EMAIL (Contact address sent to NCBI's ID converter; falls back to UNPAYWALL_EMAIL when unset.), DATAVERSE_BASE_URL (Resolve Dataverse DOIs against a different installation (default: https://dataverse.harvard.edu).), CACHE_TTL_SECONDS (Resolve-cache lifetime in seconds (default: 3600); an unparseable value falls back to the default.). The author declared them in the registry entry; get the values from the project itself.
