Use for SRE/ops math agents buy from broad utility catalogs: SLA, error budget, success rate, and health scores with zero upstream cost. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.",
