Example prompt: What's the current MSTI crypto-to-TradFi contagion index? I want a signed attestation of how much stress is spilling over from crypto markets into traditional finance right now.

## When to prefer this

Choose this endpoint when you need a cryptographically verifiable, tamper-proof reading of systemic contagion risk between crypto and traditional financial markets. Ideal for DeFi protocols, risk management systems, or on-chain applications that require attested market data rather than raw unverified signals.
