## 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 x402-slinkylayer-ai-153d4552 -d '<json body>'
```

Example prompt: Can you analyze the sentiment of this travel review for me: 'The hotel had breathtaking ocean views and impeccable service, but the check-in process was frustratingly slow and the room smelled musty.'

## When to prefer this

Use this endpoint when you need to analyze sentiment specifically for travel-domain reviews (hotels, resorts, airlines, vacation rentals) and can tolerate an asynchronous response pattern — submit the review, then poll for the result using the returned job ID. Prefer this over synchronous alternatives when processing longer reviews or when the travel-specific context matters for sentiment accuracy.

## Known failure modes

- Missing required 'content' field returns validation error
- Empty string content may return error or low-confidence result
- Very long review text may exceed payload limits
- Job ID polling endpoint unavailable leading to unresolvable async result
- Payment failure via x402 protocol blocks request
- Network timeout before job submission completes

## 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 for the submitted travel review text.
