m2m_audit_contractInspect static bytecode capabilities (e.g. mint, pause, freeze, upgradeability slots), common proxy target resolution, and coverage index for a single Base contract address. Factual capability observation only, not a safety or exploitability guarantee. Distinguishable from m2m_g…
m2m_get_gas_metricsFetch current Base gas price in wei/gwei with RPC provenance for the upstream observation. Read-only telemetry; does not inspect contract code, return token/DEX pricing, or authorize or submit transactions.
m2m_get_token_priceFetch the median Base DEX spot price in USD across up to five deepest indexed pools, with contract address, decimals, and pool provenance for one allowlisted token symbol (e.g. USDC, WETH, AERO). Does not return historical price series; contrast with m2m_get_dex_liquidity, which…
m2m_get_dex_liquidityFetch aggregate pool reserve, depth, and volume metrics across tracked Base DEX liquidity pools. Reports tracked-pool metrics only and does not filter by individual trading pair; contrast with m2m_get_token_price, which observes token spot prices.
m2m_get_whale_signalsFetch up to 50 tracked recent high-value ERC-20 transfer signals on Base with transaction hashes, token/sender/receiver addresses, amounts, and valuation provenance. Observes large on-chain transfer events without query parameter limits; does not inspect contract bytecode or que…
m2m_get_service_statusFetch operational status, upstream Base RPC quorum status, and persistence availability for M2M Sentinel infrastructure. Does not return blockchain or market telemetry.
