## 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 dexl-agents-sentiment-analysis-07816db9 -d '<json body>'
```

Example prompt: Can you analyze the sentiment of this customer review and tell me if it's positive, negative, or neutral: 'The onboarding was smooth but the support team took three days to respond to a simple question.'

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call sentiment classification with no API key setup, especially within an agentic or machine-to-machine workflow that already uses the DexL x402 payment rail. Ideal for low-volume, sporadic requests where subscription overhead is undesirable.

## Known failure modes

- Text exceeds 8000-character limit — request rejected
- Empty or missing text field — validation error
- Ambiguous or mixed-language input may reduce classification accuracy
- Payment failure via x402 protocol — request not processed
- Service temporarily unavailable — HTTP 5xx response

## How this service works

Sentiment as one of positive, negative, neutral or mixed, with a -1 to 1 score and a one-line reason. "Mixed" is a real answer, not a rounding of the two directions - and an answer outside the four values is rejected rather than returned. Fixed price per call.

## Output

A JSON object containing the sentiment output (e.g. classification label and/or score), the number of units consumed (1), and a flag indicating whether the result was served from cache.
