Evm Rpc

by Multi-chain EVM RPC (read-only) in Onchain & crypto

x402 APIPassing, checked 52 min ago

Read-only JSON-RPC against Ethereum, Base, Polygon, Arbitrum, or Optimism with built-in multi-endpoint failover - one paid call, no node or API key of your own. Prefer the named reads (block-number, chain-info, block-info, event-logs, erc721-owner, contract-code) for common tasks - they validate inputs and cost less; use this when you need a whitelisted method they do not wrap.
