  • HELIUS_API_KEYsecretOptional Helius API key — enables exact supply + DAS data in pump_snapshot.
  • NVIDIA_API_KEYsecretNVIDIA NIM key (nvapi-…) — leads the speak tool's TTS provider chain with the free Magpie TTS lane.
  • OPENAI_API_KEYsecretOpenAI TTS — the speak tool's paid backstop when the free NVIDIA lane is unavailable.
  • REPLICATE_API_TOKENsecretRequired for the generate_avatar tool (Replicate text/image-to-3D).
  • SOLANA_SECRET_KEYsecretOptional default base58 Solana secret for wallet_send / pump_buy. Per-call secret args override this. Treat like cash.
