## 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-agent-economy-lab-batch-sentiment-analysis-9e4a587d -d '<json body>'
```

Example prompt: Can you run batch sentiment analysis on these five customer comments and tell me which ones are positive, negative, or neutral: 'Great product!', 'Totally disappointed', 'Works as expected', 'Never buying again', 'Pretty good value for money'?

## When to prefer this

Choose this endpoint when you need to classify sentiment for multiple text items in a single machine-payable call using USDC on Base mainnet via x402. It is ideal for AI agents operating autonomously that need cost-controlled, pay-per-call NLP without subscription overhead. Prefer it over single-item endpoints when batching reduces round-trips, and over traditional REST NLP APIs when your pipeline requires crypto-native micropayments.

## Known failure modes

- Empty or missing text field returns validation error
- Texts exceeding token/character limits may be truncated or rejected
- Payment failure on Base mainnet (insufficient USDC, wrong chain) results in 402 Payment Required
- Tunnelmole tunnel may be offline or expired, returning connection errors
- Malformed JSON body returns 400 Bad Request
- Rate limits or per-wallet restrictions may throttle repeated calls
