## 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 nojunk-moderate-sentiment-analysis-e01746ac -d '<json body>'
```

Example prompt: Check the sentiment of this customer review and give me a polarity score: 'The delivery was fast but the product quality was really disappointing — I expected much better for the price.'

## When to prefer this

Choose this endpoint when you need fast, scored sentiment classification with a continuous polarity value rather than just a label — especially useful when ranking or filtering content by sentiment strength. Ideal for batch processing up to 50 texts per call at low cost ($0.001 per call). Prefer over heavier LLM-based sentiment when throughput, cost, and structured numeric output matter more than nuanced explanation.

## Known failure modes

- Text exceeds 20,000 character limit — request rejected with validation error
- Batch exceeds 50 items — request rejected
- Empty string submitted — rejected due to minLength constraint
- Payment not attached or insufficient — 402 Payment Required response
- Network timeout on large batches

## How this service works

Text Moderation sentiment: Sentiment of one text or a batch of up to 50: positive/negative label, score and a signed polarity from -1 to 1.

## Output

Returns a sentiment label ('positive' or 'negative'), a confidence score between 0 and 1, and a signed polarity value between -1 (most negative) and +1 (most positive) for each input text. For batch requests, results are returned as an array corresponding to each submitted text.
