x402 Health Oracle

Kernel-level L2 health oracle with 4-channel AI agent distribution. x402 micropayments on Base + Hedera.

Live: https://rtt.phoenix-ai.work | npm: phoenix-mcp-server | MCP Registry: io.github.kant19801201behax5/phoenix-mcp-server

Problem

AI agents making autonomous on-chain transactions have no way to check network health before committing funds. 64% of DeFi protocols don't verify sequencer health. Base went down for 2 hours in June 2026 with $10.95B at risk.

Existing solutions (Chainlink L2 Sequencer Feed) give binary up/down with 30-second OCR updates. Agents need nanosecond-precision RTT, revert ratios, and stall detection — before signing a transaction.
