Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

`get_cheapest_chain`	Get a direct recommendation for the cheapest EVM chain right now with savings %. Free, rate limited.
`get_gas_basic`	Find the cheapest EVM chain before sending a transaction. Compares live gas across Ethereum, Base, Arbitrum & Optimism and returns the cheapest chain with savings % (e.g. 'Use Base — saves 99.8% vs Ethereum'). Use before bridging, deploying a contract, or any tx where you can choose the chain. $0.001 USDC via x402 on Base, no API key.
`get_gas_demo`	Get free real-time gas prices for 4 major EVM chains (Ethereum, Base, Arbitrum, Optimism). Rate limited 10/hr.
`get_gas_premium`	Find the cheapest EVM chain across 9 networks before transacting. Covers Ethereum, Base, Arbitrum, Optimism, BNB, Polygon, Avalanche, zkSync & Hyperliquid; returns the cheapest chain with savings % for cross-chain routing decisions. Use when you need the widest chain coverage to route a tx to the lowest-fee network. $0.002 USDC via x402 on Base, no API key.
