ETH Verdict Chainid Bundle
https://api.arysphere.com/v1/ventures/x402_chain_reads_v1/eth_verdict_chainid_bundleOverview
Ethereum mainnet bundle: several reads in one paid call. One paid call on Ethereum mainnet (query: token): eth_chainId plus the token verdict for one token contract, each part's own result keyed by its name. Returns: each named part service's own result, in one paid call, keyed by the part's name -- exactly what each part returns when bought alone; the call succeeds only when every part answers. It takes the union of the parts' query parameters.
