ApiToll Multi-Chain EVM Gas.

GET https://evm-gas.apitoll.cloud/v1/evm/gas ↗

Multi-chain EVM gas price oracle for AI agents — 17 chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche…). One x402 call returns slow/standard/fast EIP-1559 tiers as DROP-IN maxFeePerGas + maxPriorityFeePerGas in wei (plug straight into a viem/ethers tx, no conversion, exact even on sub-gwei L2s), plus base fee, head block, and fullness, from a live eth_feeHistory call. Pass ?chain= to switch chains.

All advertised payment options are stored. Base (`eip155:8453`) is the operational network for ranking and canaries; non-Base options remain visible for transparency.
