## 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-sentiment-analysis-nvidia-nim-minimax-m3-6af4c1b9 -d '<json body>'
```

Example prompt: Analyze the sentiment of this customer review and tell me if it's positive, negative, or neutral: 'The product arrived on time but the packaging was completely crushed and two items were missing — very disappointed.'

## When to prefer this

Use this endpoint when you need AI-powered sentiment analysis backed by a large 428B MoE model (MiniMax-M3 via NVIDIA NIM) and are paying per-call with USDC on Base via x402. Prefer this over lighter-weight sentiment APIs when accuracy on nuanced or complex text matters. Good for agents that already operate in the x402 payment ecosystem.

## Known failure modes

- Missing required 'text' field — returns 400 or validation error
- Empty or blank text string — may return error or undefined sentiment
- Text too long for model context window — may truncate or error
- Payment failure via x402/USDC — returns 402 Payment Required
- Model inference timeout — returns 5xx or gateway error
- Non-English text may yield unreliable sentiment results
