● healthy

Multi-chain gas price API for AI agents. Compare gas prices across Ethereum, Base, Polygon, Arbitrum, and BSC in a single call. Find the cheapest chain for your transaction. Tools: crypto_estimate_gas. Use this when choosing between chains for deployment, bridging decisions, or cross-chain cost optimization. IMPORTANT: For Ethereum-only gas, use gas_get_current_price for more detail. Returns gas prices for all chains in one response. No API key required — x402 micropayment $0.002/call on Base L2.
