## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Choose this endpoint when you need an OpenAI SDK-compatible chat completions interface backed by Gemma 4 12B, want to pay per-call via x402 micropayments rather than a subscription, or want to avoid hosting Ollama/Gemma infrastructure yourself. Prefer over other bittensorman.xyz endpoints when you need a general-purpose LLM completion rather than a specialized FX analysis or trading workflow.
