Call when an agent needs the ERC-721 token ids one wallet owns in an Ethereum collection, via tokenOfOwnerByIndex when enumerable (at most 100). Unsupported enumeration errors and is not billed. No log scan. Send JSON {"contract":"0x1111111111111111111111111111111111111111","owner":"0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"}. Exact $0.005 USDC on Base. Try unpaid POST /v1/sandbox/eth-erc721-tokens first.
