## 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 agent-micro-text-sentiment-analysis-0fced7d9 -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 product arrived on time and works perfectly, but the packaging was a bit damaged.'

## When to prefer this

Choose this endpoint when you need a cheap, fast, per-call sentiment classification for text within an AI agent pipeline and want to pay in USDC micropayments via x402 without a subscription. It is ideal for agents that need ad-hoc NLP sentiment scoring at sub-cent cost without setting up a full NLP service integration.

## Known failure modes

- Missing or empty 'input' field in request body returns a 400 validation error
- Payment not included or insufficient USDC via x402 returns a 402 Payment Required
- Non-JSON body or wrong Content-Type may cause a parse error
- Very short or ambiguous text may return low-confidence or unexpected sentiment labels
- Service unavailability on the Cloudflare Workers edge may return a 503

## How this service works

Advanced micro-tools for AI agents: cryptographic randomness, text analysis, math helpers, date arithmetic, web metadata, and IP intelligence. All under $0.01 per request, paid in USDC via x402.

## Output

Returns a JSON object with an 'ok' boolean and sentiment classification details for the submitted text — typically including a sentiment label (positive, negative, neutral) and optionally a confidence score or polarity value.
