`evm_block`Use when you need a block header on Base, Ethereum, Arbitrum, Polygon or Optimism: latest or a given number, with hash, parent, timestamp, miner, gas used/limit. Returns the paid x402 request for your input (GET /evm/block, $0.001 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. Block header only; for one transaction use evm_transaction or evm_receipt. First call each day returns the data itself, free; later calls return the paid request.
