Ethereum mainnet eth_getBlockByNumber: takes block (a block number, or 'latest') and returns that block exactly as the node gives it.

GET https://ari001.tailb4ac3a.ts.net/v1/ventures/x402_chain_reads_v1/eth_getblockbynumber. Same payment terms as that HTTP route. Call once with no payment. The result is the payment terms. Retry the same call with the signed payment at _meta["x402/payment"].
