https://soren.com/v1/chain/codeOverview
Read whether an address is a contract, and its code size, live from Base mainnet, for a fraction of a cent. No API key, no account — a wallet is the only requirement, and you are charged only if the read succeeds. Plain unsigned data; the attested version of chain reads is /v1/oracle/onchain. Answers are read at the moment of the call and stamped with the block they came from where applicable.
