Phoenix Zero L2 Health Oracle

Endpoints (8 live)

• GET /api/v1/health-proof — Cryptographic proof of node health. HMAC-SHA256 commitment over 8-layer security assessment (PQC, Frankenstein, Spearman, entropy, jitter) plus eBPF XDP/LSM status. Verifiable without revealing raw metrics. (0.01 USDC on Base)
• POST /api/v1/classify — Silicon DNA agent identity classification. Analyzes TLS fingerprint, timing jitter, behavioral entropy to classify as HUMAN, LEGIT_AGENT, or MALICIOUS_BOT. Physical-layer NIC fingerprinting. (0.01 USDC on Base)
• GET /api/v1/price — Current x402 pricing with surge multiplier. Price increases 10x during sequencer stalls and MEV storms. (0.01 USDC on Base)
• GET /api/v1/safe — Boolean pre-flight check for L2 transaction safety across all 12 chains (?chain= param, default: base). Returns safe=true/false with reason code. Optimized for high-frequency agent calls before submitting transactions. (0.01 USDC on Base)
• GET /api/v1/chains/1 — Single-chain sequencer health. Returns P99/P95 RTT, stall flag, revert ratio for one of 12 monitored L2 chains. (0.01 USDC on Base)
• GET /api/v1/correlation — 12x12 cross-chain temporal correlation matrix R_xy and Frobenius anomaly score A(t). Paper Section 3: synchronized activity detection across all chains. A spike in A(t) indicates a new coordinated source (MEV cluster, bot farm). (0.01 USDC on Base)
• POST /api/v1/preflight — Deterministic pre-flight transaction safety decision. Returns PASS/DEGRADED/FAIL with cryptographic evidence of observed network state at decision time. Machine-readable policy. Designed for autonomous agents that need provable execution decisions. (0.01 USDC on Base)
• GET /api/v1/health — Real-time L2 sequencer health across 12 chains (Base, Arbitrum, Optimism, zkSync, Blast, Linea, Mantle, Mode, Scroll, Taiko, Polygon zkEVM, Casper). Returns kernel-level P99/P95 RTT from eBPF probes, revert ratios, gas pressure, and execution recommendation. (0.01 USDC on Base)
