Northline ChainKit x402 MCP
Live block height, gas price and fee estimates (transfer, ERC-20 transfer, contract call) for Base or Arc. On Arc fees are quoted directly in USDC.
226 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Live block height, gas price and fee estimates (transfer, ERC-20 transfer, contract call) for Base or Arc. On Arc fees are quoted directly in USDC.
Ethereum gas prices: rapid, fast, standard, and slow tiers in gwei plus ETH spot price. Use when an agent must time transactions or estimate fees before submitting on-chain operations.
