Possible values: `"Fraud"`, `"Not Fraud"`, `"Investable"`, `"Not Investable"`, `"Safe"`. | | probabilityFraud | number | `0.5488` | Rug pull probability score ranging from `0.0` to `1.0`. | | contractCreationTime | string (ISO 8601) | `"2021-11-10T12:00:00.000Z"` | Exact timestamp when the smart contract was deployed. | | lastChecked | string (ISO 8601) | `"2026-03-25T18:42:00.000Z"` | Timestamp of the most recent security and fraud analysis. | | chain | string | `"ETH"` | The network/blockchain name (e.g., `"ETH"`). | | forensic\_details | object | *See sub-fields below* | Deep analysis of the contract's security properties. Core flags are binary: `0` (clean) or `1` (flagged). | | ↳ `.contract_name` | string | `"PFToken"` | The registered name of the smart contract. | | ↳ `.is_open_source` | number (0/1) | `1` | Indicates if the source code is verified on the network explorer. | | ↳ `.is_proxy` | number (0/1) | `0` | Indicates if the contract uses a proxy pattern (allowing the underlying logic to be replaced). | | ↳ `.selfdestruct` | number (0/1) | `0` | Indicates if the contract contains a `selfdestruct` function capability. | | ↳ `.privilege_withdraw` | number (0/1) | `0` | Indicates if the owner has excessive privileges to arbitrarily withdraw user assets. | | ↳ `.withdraw_missing` | number (0/1) | `0` | Indicates if critical withdrawal mechanisms are missing, preventing users from recovering funds. | | ↳ `.blacklist` | number (0/1) | `0` | Indicates if the contract owner has the power to blacklist specific wallet addresses. | | ↳ `.approval_abuse` | number (0/1) | `0` | Indicates if the owner can potentially abuse token allowances/approvals given by users. | | ↳ \`.owner\*\* | object | *See sub-fields below* | Details regarding the administrative ownership of the smart contract. | | ↳ `.owner_type` | string | `"contract"` | The type of owner account. Possible values: `"contract"` (Multi-sig/DAO/Other contract) or `"eoa"` (Externally Owned Account/Regular wallet). | | ↳ `.owner_address` | string (nullable) | `null` | The public address of the owner. Returns `null` if the contract ownership has been renounced. | ## Error Handling | Status | Description | | ------ | --------------------------------- | | 400 | Invalid network or missing fields | | 401 | Missing or invalid auth | | 402 | Insufficient balance | | 502 | Provider error | --- # Agent Instructions This documentation is published with GitBook.
