multi_chain_gas
Read-onlyIdempotent
Which chain is cheapest to operate on right now — Reads the live gas price on each major EVM chain an agent uses (base, arbitrum, optimism, ethereum, polygon) and turns it into the USD cost of the actions that matter — a plain transfer and a DEX swap — using live native-token prices. Returns one ranked answer with the cheapest chain, so an agent deciding where to settle doesn't make five RPC calls. A chain it could not read is 'unknown' and excluded from the pick, never guessed. Gas units are typical estimates. Not financial advice. Priced $0.01 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
