## 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 agentutility-sales-call-sentiment-analyzer-bc1078e9 -d '<json body>'
```

Example prompt: Can you analyze the sentiment of this sales call transcript and tell me whether it was positive, negative, or mixed — and give me an overall sentiment score? Here's the transcript: 'Thanks for reaching out, I'm somewhat interested but I have some concerns about pricing...'

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call sentiment score on a sales call transcript without setting up a full NLP pipeline. Ideal for AI agents automating sales call review, CRM enrichment, or coaching workflows where USDC micropayments per call are acceptable. Prefer over general-purpose sentiment APIs when you specifically want sales-context sentiment scoring with a normalized 0–1 score output.

## Known failure modes

- Empty or missing transcript/audio input returns an error
- Transcript too long may be truncated or rejected
- Non-sales conversation content may yield low-confidence or unexpected results
- Payment failure via x402 returns 402 status before processing
- Malformed JSON request body returns 400 error
