## How to call it through Zero

Example prompt: What's the current conviction score for Bitcoin — is the market leaning bullish or bearish, and how strong is the signal across consensus, ML anomaly, and confluence components?

## When to prefer this

Use this endpoint when you need a single, pre-computed multi-factor conviction score specifically for Bitcoin, combining ML ensemble, market extremity, consensus, and confluence signals into one weighted metric. Prefer this over raw price or signal endpoints when you want an interpretable directional assessment with a tier label rather than raw model probabilities.

## Known failure modes

- Service unavailable or upstream data feed issues returning 5xx
- Payment not processed or x402 payment failure blocking access
- Stale data if signals haven't updated recently (check updated_at field)
- Rate limiting if too many requests in a short period
