## 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 momoai-text-classification-194258a9 -d '<json body>'
```

Example prompt: Classify this customer review as positive, negative, or neutral and give me the result: 'The delivery was lightning fast but the packaging was completely crushed.'

## When to prefer this

Choose this endpoint when you need quick, pay-per-call text classification without a subscription, especially when paying with USDC on Base via x402 protocol. Ideal for low-volume or sporadic classification tasks where you want to provide your own custom label set rather than using a fixed taxonomy.

## Known failure modes

- Missing required 'text' field returns validation error
- Invalid or empty categories array may produce undefined classification behavior
- Payment failure or insufficient USDC balance returns 402 Payment Required
- Oversized text input may exceed model context limits
- Ambiguous or conflicting categories may reduce classification confidence
