Boolean pre-flight check for L2 transaction safety across all 12 chains (?chain= param, default: base). Returns safe=true/false with reason code. Revert ratio data available for Base and Arbitrum only (eth_getBlockReceipts); other chains use RTT-only analysis. Optimized for high-frequency agent calls.

  • GET/healthNo price listedReal-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 (Base and Arbitrum via eth_getBlockReceipts), gas pressure, and execution recommendation.
  • POST/classifyNo price listedSilicon DNA agent identity classification. Behavioral timing analysis: CPU jitter entropy (L0), Shannon entropy (L2), Spearman rank correlation (L3) to classify as HUMAN, LEGIT_AGENT, MALICIOUS_BOT, SYBIL, or UNKNOWN (no evidence either way). Per paper Section 5.1.
  • GET/health-proofNo price listedHMAC-SHA256 integrity commitment over node health assessment and eBPF XDP/LSM status. Provides tamper evidence (BLAKE3+Ed25519 per paper Section 6.3). Not a zero-knowledge proof.
  • GET/priceNo price listedCurrent x402 pricing with surge multiplier. Price increases 10x during sequencer stalls and MEV storms.
