## 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 sentiment-analyzer-batch-api-42befeae
```

Example prompt: Can you analyze the sentiment of these 5 customer reviews all at once: 'Great product!', 'Terrible experience, never again.', 'It was okay, nothing special.', 'Absolutely love it!', 'Shipping was slow and packaging was damaged.'

## When to prefer this

Prefer this endpoint over the single-text sibling when you need to analyze more than one text and want to minimize API call costs and latency — processing up to 20 texts in a single $0.10 USDC call is far more efficient than making 20 individual requests. Ideal for bulk review analysis, survey processing, or any pipeline where you have multiple texts queued for sentiment scoring.

## Known failure modes

- Exceeding the 20-text batch limit may result in a rejection or truncation error
- Empty or null text entries in the array may cause individual item errors
- Very long individual texts may be truncated or rejected
- Payment failure via x402 protocol will block the request
- Malformed input array (non-string elements) may cause a 400 bad request
- Network timeouts if the batch is large with lengthy texts

## How this service works

Analyze sentiment of up to 20 texts in batch
