## 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 pagos-andreax-dev-text-topic-classifier-69f8009d
```

Example prompt: Can you classify this text by topic: 'Our server keeps crashing every time we deploy a new build and we need urgent help from the infrastructure team'?

## When to prefer this

Choose this endpoint when you need fast, high-volume topic/category classification of text strings for routing or labeling pipelines. Prefer it over general-purpose LLM inference when you want a lightweight, cost-effective ($0.002/call) classification without the overhead of a full generative response. Use it alongside the sibling sentiment classifier when you need both sentiment and topic labels simultaneously.

## Known failure modes

- Missing 'input' query parameter returns a validation error
- Empty or very short text may produce a low-confidence or generic category
- Ambiguous multi-topic text may be classified under only the dominant theme
- Rate limiting or payment failures may return 402 or 429 HTTP errors
