Gas Estimator API
Estimate gas across ETH, Base, Polygon, Arbitrum, and BSC before your agent submits transactions or deployment scripts.
Overview
Gas Estimator is an MCP server for the Ship phase that estimates transaction gas across ETH, Base, Polygon, Arbitrum, and BSC.
What is this MCP server?
- Multi-chain gas estimation for ETH, Base, Polygon, Arbitrum, and BSC
- Remote MCP SSE at gas-estimator.api.klymax402.com (v1.1.0)
- x402 micropayment on the Gas Estimator API
- Helps agents quote costs before mint, deploy, or bridge flows
- Infrastructure MCP—not a wallet signer or transaction broadcaster
- Version 1.1.0
- Five chains: ETH, Base, Polygon, Arbitrum, BSC
- Remote SSE MCP on gas-estimator.api.klymax402.com
What problem does it solve?
Agents and scripts guess gas at deploy time and blow budgets or fail txs on the wrong chain assumptions.
Who is it for?
Indie builders shipping multi-chain dApps or deploy automation who want quick MCP gas quotes across five listed networks.
Skip if: Teams needing historical gas analytics only, custom L2s outside the five chains, or fully offline estimation.
What do I get? / Deliverables
You get chain-specific gas estimates inside the agent workflow before signing or broadcasting transactions.
- Per-chain gas estimates for planned transactions
- Agent-readable fee context before mainnet or L2 submits
