## 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`):

```sh
zero fetch --capability singit-ask-grok-4-7-chat-completions-482341cb -d '<json body>'
```

Example prompt: Ask Grok 4.7 to explain the reasoning behind the trolley problem in philosophy — keep the answer under 800 tokens and use a conversational tone.

## When to prefer this

Choose this endpoint when an agent specifically needs xAI's Grok 4.7 model for its distinctive reasoning style, without setting up an xAI developer account or managing API keys. It is ideal for pay-per-call pipelines using the x402 micropayment protocol, OpenAI-SDK-compatible integrations, or when comparing Grok 4.7 against other frontier models through a unified interface. Prefer alternatives on this platform when a different model (Claude, GPT, Gemini, DeepSeek) is needed.

## Known failure modes

- Input messages exceed 24,000 characters — request rejected
- max_tokens set above 1,200 — capped or rejected
- Payment via x402 fails or USDC balance insufficient — 402 response
- Model id provided but not found on /v1/models — model not found error
- Empty or malformed messages array — validation error
- Rate limiting or upstream xAI service unavailability — 5xx error
