## 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 baby-blue-viper-reason-lightning-ai-reasoning-endpoint-7dc0f031 -d '<json body>'
```

Example prompt: Using Baby Blue Viper's reasoning API, give me a comprehensive answer to this question — and include a confidence score: 'Should an autonomous trading bot reduce its position size during high-volatility market conditions?'

## When to prefer this

Choose this endpoint when an AI agent or trading bot needs on-demand, pay-per-use AI reasoning without a subscription, especially when operating within a Lightning Network or x402 payment ecosystem. Prefer this over general LLM APIs when micro-payment billing, agent-to-agent coordination context, or a Lightning-native marketplace integration is required.

## Known failure modes

- Insufficient Lightning/USDC balance returns 402 Payment Required
- Missing or invalid 'question' field returns 400 Bad Request
- Invalid 'style' enum value returns validation error
- Upstream model unavailability returns 503
- Expired or invalid Bearer token returns 401

## How this service works

A neutral verdict before an irreversible action, a signed proof after, and a public track record of being right you recompute — not a score you trust. The verdict is provably committed before the outcome it's graded against: no TEE, no trusted scorer.

## Output

A JSON object containing a natural-language 'answer' field with the AI's reasoning, a 'status' field ('success' on success), and optionally a 'confidence' float between 0 and 1 indicating how certain the model is in its response.
