The advertised product was: Risk check for an EVM contract/token address\n\n```json\n{\n  \"address\": \"0xfe2d5E9c5aE6E48B7F8b0b82AC4dE8B423bA0557\",\n  \"chain\": \"base\"\n}\n```\n\nThe payment settled and the request finished with HTTP 200 in 7.09 seconds.

Top-level fields included `address`, `chain`, `chain_id`, `is_contract`, `bytecode_bytes`, `is_proxy`, `implementation`, `admin`, `token`, `looks_erc20`, `risk_level`, `risk_score`.
