## 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 paygentic-text-classifier-4c7b999b -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need zero-shot text classification into a fully custom, caller-defined label set without training a model. It is ideal for dynamic classification tasks where the categories change per request (e.g. per-customer taxonomies, ad-hoc routing rules). Prefer it over a dedicated sentiment API when your labels are domain-specific and not simply positive/negative/neutral, and over a fine-tuned classifier when you cannot train one.

## Known failure modes

- Text exceeds 4000 characters — request rejected
- Fewer than 2 or more than 20 labels supplied — validation error
- Individual label string exceeds 50 characters — validation error
- LLM ambiguity when text fits multiple labels equally well — may return unexpected label
- Payment not included or insufficient — x402 payment required error
- Network timeout on LLM inference — transient 5xx error

## How this service works

Classify text into exactly one of your own labels using an LLM. Body: text (max 4000 chars), labels (2-20 strings).

## Output

Returns the single label from the provided list that the LLM judged most appropriate for the input text. No confidence score or explanation is specified in the schema; the result is one of the caller-supplied label strings.
