## 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-qwen3-8-max-chat-completions-329a0cd7 -d '<json body>'
```

Example prompt: Ask Qwen3.8 Max to write a Python function that parses nested JSON and flattens it into a single-level dictionary, and keep the answer under 800 tokens.

## When to prefer this

Choose this endpoint when you specifically need Alibaba's Qwen3.8 Max model for coding or complex reasoning tasks, and you want an OpenAI-compatible interface without setting up an Alibaba Cloud account or API key. Prefer this over generic LLM endpoints when Qwen3.8 Max's strengths in code generation and structured reasoning are required, or when comparing outputs across model families.

## Known failure modes
