Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 minichan-nvidia-nim-minimax-m3-chat-api-3517f140 -d '<json body>'
```

Example prompt: Ask the MiniMax-M3 428B model through MiniChan: 'Explain the key differences between mixture-of-experts and dense transformer architectures in 3 paragraphs' — use temperature 0.5 and allow up to 800 tokens.

## When to prefer this

Choose this endpoint when you need a high-capacity 428B MoE language model for complex reasoning, creative, or multimodal tasks and are willing to pay $0.05 USDC per call via x402 on Base — ideal for agents that need large-model quality without managing their own NVIDIA NIM infrastructure.

## Known failure modes

- Missing required 'prompt' field returns a 400 error
- Payment not completed in USDC on Base results in 402 Payment Required
- Prompt too long or max_tokens exceeds model limit causes a 400 or 500 error
- Temperature outside valid range may be ignored or cause a validation error
- Model inference timeout causes a 503 or 504 response
- Invalid JSON body returns a 400 parse error

## How this service works

NVIDIA NIM MiniMax-M3 (428B MoE) powered API for AI agents. 15 multimodal endpoints — text, vision, code, reasoning, creative. Pay with USDC on Base via x402.

## Output

A JSON object containing the AI-generated text response from the MiniMax-M3 428B MoE model based on the submitted prompt, with length and style influenced by the max_tokens and temperature parameters.
