## 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 support-ticket-classifier-2ef61963
```

Example prompt: Classify this support ticket — 'My subscription was charged twice this month and I can't reach anyone for a refund' — into one of these labels: billing, technical issue, account access, general inquiry, and tell me the confidence score and second-best label.

## When to prefer this

Choose this endpoint when you need fast, custom-label text classification with a confidence score and a runner-up label, especially for support ticket routing, review categorization, or any arbitrary label taxonomy you define yourself. It's ideal when you want to avoid training a custom model and need a sub-4.5s response with a fallback guarantee. Prefer it over fixed-label sentiment classifiers when your labels are domain-specific or change frequently.

## Known failure modes

- Fewer than 2 or more than 20 labels provided — request rejected
- Text exceeds 4000 characters — likely truncation or rejection
- Both Jev and Groq fallback unavailable — timeout or 503 error
- Ambiguous text with nearly equal label scores — low confidence score with unreliable alternate label
- Payment not received or insufficient USDC — 402 payment required error

## How this service works

Text classification with your own custom labels (2-20) - categorize a support ticket, a review, or any text into the best-fitting label, with a confidence score and an alternate label. Powered by Jev, falling back to a Groq-hosted LLM if Jev is slow or unavailable - under 4.5s guaranteed. Try GET /classify/sample.

## Output

Returns the best-fitting label from your provided list, a confidence score (0–1), and an alternate (runner-up) label — delivered in under 4.5 seconds guaranteed.
