## 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 kimi-moonshot-ai-llm-via-x402engine-3b9c1fd0 -d '<json body>'
```

Example prompt: Use Kimi — Moonshot AI's flagship model — to analyze this 50-page contract and summarize the key obligations and risk clauses for me.

## When to prefer this

Choose this endpoint when you need Moonshot AI's Kimi model specifically — valued for its strong reasoning capabilities and very long context window — and want to pay per call without a monthly subscription. Ideal for agents that need to process large documents or run complex multi-step reasoning tasks on-demand. Prefer this over OpenAI or Anthropic endpoints when Kimi's long-context strengths are a better fit for the task, or when cost-per-call micropayment billing via x402 is required.

## Known failure modes

- Insufficient USDC balance causes 402 payment failure
- Prompt exceeds model's context window limit
- Network timeout on long-running reasoning tasks
- Malformed request body returns 400 error
- Rate limiting if too many concurrent requests are made
- Model unavailability or provider-side outage returns 503
