## 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 kihustle-subjectivity-analysis-api-30617e5b -d '<json body>'
```

Example prompt: Can you run a subjectivity analysis on this sentence and tell me whether it's expressing an opinion or a factual statement: 'This product completely changed my life and is absolutely the best on the market.'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call subjectivity detector for short text inputs at a very low cost ($0.002 per call). It is suitable for agents that need to quickly flag opinionated or biased content without running a full sentiment or emotion analysis pipeline. Best for scenarios where fact vs. opinion distinction matters, such as content moderation, review filtering, or editorial quality checks.

## Known failure modes

- Missing or empty 'text' field in request body — likely returns an error or unexpected result
- Text too long for processing — may cause timeout or malformed response
- Non-UTF-8 or malformed string input — may result in processing failure
- Service unavailability — HTTP 402 or 5xx if payment or server issues arise
- Ambiguous response schema — the generic 'processed/success' response may not reliably expose subjectivity classification details
