## 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 vextorium-market-sentiment-analyzer-4fd92fb3 -d '<json body>'
```

Example prompt: Can you analyze the market sentiment of this tweet: 'Bitcoin ETF approval is imminent, institutions are piling in — this is the start of the bull run'? I want to know if it's bullish, bearish, or neutral, the confidence score, and which crypto assets are mentioned.

## When to prefer this

Choose this endpoint when you need financial market sentiment analysis on arbitrary text in any language, especially when you want a structured output including score, confidence, and asset extraction in a single call. It is well-suited for crypto and DeFi-focused sentiment pipelines, multilingual content, and when you want local AI inference (Qwen2.5-7B) rather than a cloud LLM dependency.

## Known failure modes

- Empty or missing 'texto' field returns an error
- Extremely long text may exceed model context window
- Ambiguous or non-financial text may return neutral with low confidence
- Network or inference timeout if local model is busy
- Non-JSON body type may cause parsing errors

## How this service works

Market sentiment of any text (news, posts, tweets; any language) via local AI (Qwen3-8B): bullish / bearish / neutral, score -1 to 1, confidence, mentioned assets and a short reason.

## Output

Returns a JSON object with: 'sentimiento' (bullish/bearish/neutral string), 'puntuacion' (float score from -1 to 1), 'confianza' (confidence float 0 to 1), 'activos_mencionados' (array of mentioned asset names), 'motivo' (short text reason for the classification), 'modelo' (model name used), and 'aviso' (optional warning string if applicable).
