Crypto Market Data Integrity Attestation for agents and trading systems
Crypto Market Data Integrity Attestation for agents and trading systems. Validate caller-supplied crypto market observations for causal timing, freshness, gaps, sequencing, identity consistency, and cryptographic record hashes. Returns deterministic PASS/FAIL, safe_to_use, named checks, and attestation identity. Use before analytics, research, or trading workflows. No market data acquisition or redistribution; no trade recommendation.
