## 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 hermes-micro-agent-sentiment-analysis-a6c161c8 -d '<json body>'
```

Example prompt: Can you run a sentiment analysis on this customer review: 'The product arrived fast but the packaging was completely crushed and the instructions were missing' — I need to know if it's positive, negative, or neutral.

## When to prefer this

Choose this endpoint when you need a fast, per-call paid sentiment classification without a subscription, especially in agent workflows that already use HTTP 402 / x402 micropayments on Base (USDC). It is well-suited for one-off or low-volume sentiment checks where a lightweight pay-per-use model is preferred over a SaaS API key setup.

## Known failure modes

- Payment not verified on-chain — request rejected before execution
- Missing 'prompt' field — returns error about required input
- Ambiguous or empty text input — may return low-confidence or generic result
- Network or Base blockchain latency delays payment verification
- Malformed JSON body — HTTP 400 bad request

## How this service works

20 paid AI and data micro-tasks over HTTP 402 on Base (USDC): summarize, extract, keywords, sentiment, translate, rewrite, proofread, python_debug, code_lint, code_explain, code_refactor, code_review, json_minify, json_query, csv_to_json, hash, base64, convert, describe_image, probe_media. Each call is priced per-task and verified on-chain before execution.

## Output
