## 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 ai-sentiment-score-35eb327b
```

Example prompt: Can you run a sentiment analysis on this text and tell me if it's bullish, neutral, or bearish with a score and brief rationale: 'The Fed signaled multiple rate cuts ahead, sending crypto markets sharply higher in early trading.'

## When to prefer this

Choose this endpoint when you need a fast, structured sentiment verdict with a numeric score and rationale in a single call — ideal for pre-trade context, news triage pipelines, or any agent workflow that needs to classify financial or market text without building a custom NLP layer. Prefer it over general-purpose LLM sentiment prompts when you want a consistent -1 to 1 scale with explicit bullish/neutral/bearish labels and a pay-per-call model with no subscription overhead.

## Known failure modes

- Text exceeding 4000 characters may be rejected or truncated
- Empty or missing 'text' query parameter returns an error
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Ambiguous or very short text may yield a neutral score with low confidence rationale
- Rate limiting or Cloudflare worker cold-start may cause occasional latency spikes

## How this service works

AI sentiment analysis in one call (?text=...): verdict bullish/neutral/bearish, score -1..1, one-line rationale — pre-trade context and news triage for agents

## Output

Returns a JSON object with three fields: 'verdict' (one of bullish, neutral, or bearish), 'score' (a float from -1.0 to 1.0 where -1 is most bearish and 1 is most bullish), and 'rationale' (a concise one-line explanation of the sentiment assessment).
