Gas Oracle API
Let your coding agent quote live Ethereum and Base gas in gwei and USD before you submit transactions or tune contract flows.
Overview
Gas Oracle is an MCP server for the Build phase that returns real-time Ethereum and Base gas tiers, gwei levels, and USD cost estimates via a remote SSE endpoint.
What is this MCP server?
- Live gwei tiers for Ethereum and Base networks
- USD cost estimates alongside raw gas metrics
- Remote MCP over SSE at gas-oracle.api.klymax402.com
- x402 micropayment access—no self-hosted oracle node
- Version 1.1.0 Gas Oracle API with GitHub source gas-oracle-x402
- Supports Ethereum and Base networks
- Remote MCP URL: https://gas-oracle.api.klymax402.com/mcp (SSE)
- Server version 1.1.0
What problem does it solve?
Solo builders waste time and money when agents and scripts use stale or hand-waved gas assumptions on Ethereum and Base.
Who is it for?
Indie web3 builders who want quick, agent-queryable gas quotes on Ethereum and Base without maintaining custom RPC analytics.
Skip if: Teams that need historical gas charts, private mempool data, or chains beyond Ethereum and Base.
What do I get? / Deliverables
Your agent can pull current gwei tiers and USD estimates through MCP so transaction planning and user messaging match live network conditions.
- Live gwei tier breakdowns for supported chains
- USD-denominated gas cost estimates for agent-driven planning
- Queryable fee context inside your build workflow without a custom oracle
Recommended MCP Servers
Journey fit
Gas estimation is something you wire in while building chain-backed products, not a one-time launch chore. Remote oracle data belongs on the integrations shelf next to other third-party APIs your agent calls from the codebase.
How it compares
Remote gas-pricing MCP API with x402 billing, not a local Claude skill or wallet extension.
Common Questions / FAQ
Who is Gas Oracle for?
Solo and indie developers building on Ethereum or Base who want their AI coding agent to fetch live gas and USD estimates during integration work.
When should I use Gas Oracle?
Use it while wiring transactions, estimating deploy or mint costs, or drafting accurate fee copy before you ship on-chain features.
How do I add Gas Oracle to my agent?
Add the remote MCP server URL https://gas-oracle.api.klymax402.com/mcp (SSE) in your client’s MCP config and ensure x402 micropayment access per the gas-oracle-x402 repo.
