## 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 manylives-ai-text-sentiment-analysis-f6f2cd58 -d '<json body>'
```

Example prompt: Can you analyze the sentiment of this customer review and tell me the score, overall sentiment, and any emotions detected: 'The delivery was fast and the result was exactly what we needed. Great service!'

## When to prefer this

Choose this endpoint when you need a fast, per-call sentiment analysis with emotion detection and an explanatory reason — especially in agentic pipelines that require pay-as-you-go pricing with no account setup, or when you need on-chain verifiable provenance of the call via the Base/x402 payment rail.

## Known failure modes

- Text exceeds 20,000 character limit — request rejected
- Empty or missing 'text' field — validation error returned
- Payment not settled via x402 micropayment — 402 Payment Required response
- Network timeout for very long texts close to the character limit
- Ambiguous or mixed-sentiment text may produce low-confidence scores

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

Returns a JSON object with a numeric sentiment score (e.g. 0.7), a sentiment label (positive/negative/neutral), a list of detected emotions (e.g. ['joy','satisfaction']), and a short natural-language reason explaining the classification.
