## 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 x402-shizu-me-text-classifier-27c9ad40 -d '<json body>'
```

Example prompt: Classify this customer message into exactly one of these labels — 'billing', 'technical_support', 'sales', or 'general_inquiry': 'Hi, I was charged twice for my subscription this month and need a refund.'

## When to prefer this

Choose this endpoint when you need deterministic, single-label classification with zero prompt engineering — ideal for loops, moderation queues, routing pipelines, and triage workflows where you control the label taxonomy and need a consistent one-of-N answer at a flat per-call price. Prefer it over general-purpose LLM calls when you want classification without babysitting output format.

## Known failure modes

- Text exceeds 4000 UTF-8 bytes — request rejected
- Fewer than 2 or more than 20 labels provided — validation error
- Empty text or empty labels array — malformed request
- Payment failure or insufficient USDC balance — 402 Payment Required
- Network timeout on the classification model — 5xx error

## How this service works

Classify text into YOUR labels in one call. Body: {text (<=4000 utf-8 bytes), labels (2-20 strings)}. Returns {label} — always exactly one of your labels. Flat price, no prompt engineering needed. Use in loops for routing, moderation queues, lead triage, sentiment buckets, intent detection.

## Output

Returns a JSON object with a single 'label' field containing exactly one of the strings you provided as candidate labels — no confidence score, no explanation, just the label.
