## 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 slinkyllayer-travel-review-sentiment-analysis-7635763b -d '<json body>'
```

Example prompt: Can you analyze the sentiment of this travel review for me: 'The hotel had stunning ocean views and impeccable service, but the check-in process was frustratingly slow and the room smelled musty' — I need to know if it's overall positive, negative, or mixed?

## When to prefer this

Choose this endpoint when you specifically need sentiment analysis scoped to travel and hospitality reviews, and can tolerate an asynchronous (job-based) workflow where you submit first and poll for results. It is well-suited for agents that process guest reviews, tourism feedback, or hotel testimonials and need a lightweight, pay-per-call sentiment classifier without managing your own NLP infrastructure. Prefer alternatives if you need synchronous real-time sentiment results or if the review content is outside the travel/hospitality domain.

## Known failure modes

- Missing or empty review text in request body returns validation error
- Invalid or malformed JSON payload causes 400 bad request
- Insufficient USDC payment ($0.1 required) results in payment failure via x402 protocol
- Job ID returned but downstream sentiment model unavailable causes job to stall
- Polling the job status before processing completes returns pending status — result not yet available
- Rate limiting if too many concurrent submissions are made

## How this service works

Submit a travel review for sentiment analysis. Returns a job identifier that can be used to query the job status and retrieve the sentiment result.

## Output

Returns a job identifier (job ID) that can be used to poll a separate status endpoint to retrieve the completed sentiment analysis result, which includes the sentiment classification (e.g. positive, negative, neutral/mixed) and likely a confidence score or sentiment breakdown for the submitted travel review.
