Gas Oracle API

Pulls real-time gas price data for Ethereum and Base networks through a dedicated API endpoint. You get current gwei rates across priority tiers (low, medium, high) and USD cost estimates for common operations like swaps and transfers. Built with x402 USDC micropayments integration, so each API call costs a small amount rather than requiring API keys or subscriptions. Reach for this when you're building crypto tools that need to help users time transactions or estimate fees before they commit. The MCP server connects via SSE transport and talks to gas-oracle.api.klymax402.com under the hood.
