  • LLM_API_KEYsecretBearer token for the LLM endpoint (LLM_API_BASE); omit for keyless local servers.
  • EMBEDDING_API_KEYsecretBearer token for the embeddings endpoint (EMBEDDING_API_BASE); omit for keyless local servers.
  • DATA_GOV_API_KEYsecretOptional 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.
