• NCBI_API_KEY secret — 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 secret — 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 secret — 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 secret — 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.
