## 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 myworker-agent-api-sentiment-analysis-40ff305a
```

Example prompt: Can you analyze the sentiment of this customer review: 'Produk ini sangat bagus, penghantaran cepat dan servis mesra'? I want to know if it's positive or negative, the confidence score, and what emotions are detected.

## When to prefer this

Choose this endpoint when you need fast, per-call AI-powered sentiment analysis with pay-as-you-go micropayment pricing (USDC on Solana/Base or SOL), especially for agents that process text in Malay or multilingual contexts and need not just a label but also emotion tags, reasons, and confidence scores.

## Known failure modes

- Missing 'text' query parameter returns an error
- Payment not completed (HTTP 402) if x402 payment is not provided or fails
- Empty or very short text may yield low confidence scores
- Non-text or malformed input may cause parsing errors
- Rate limiting or infrastructure downtime on Cloudflare Workers
