# AgentForge Contract Admin Activity Monitor

> AgentForge Contract Admin Activity Monitor is a paid API for AI agents from agentforge-taupe.vercel.app, paid per call via x402, $0.025/call, status unknown (last checked 2026-10-01).

Scans a smart contract's recent history for admin-level events — ownership transfers, implementation upgrades, and pause/unpause state changes — and flags them for security review.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentforge-contract-admin-activity-monitor-3d9f36d1
```

Example prompt: Can you check if there have been any ownership transfers, upgrades, or pause-state changes on the contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum over the last 48 hours?

## When to prefer this

Choose this endpoint when you need to specifically audit admin-level control changes (ownership, upgrades, pause states) on a known contract address rather than performing a full vulnerability scan or broad token due diligence. It is ideal for security teams, governance monitors, and DeFi risk agents that need to detect unauthorized or unexpected administrative actions on a contract in near-real-time across major EVM chains.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Chain not supported returns a validation error (only ethereum, base, polygon, arbitrum, optimism, avalanche allowed)
- lookbackHours exceeding 168 (7 days) returns a validation error
- Contract with no admin events in the window returns an empty flags list
- RPC or indexing delays may cause recent events to be missing
- Non-upgradeable or non-pausable contracts may return no relevant events even if active

## How this service works

Admin activity monitor for contract owners and security teams: flags ownership transfers, implementation upgrades, and pause-state changes in a contract's recent history. Category: data.

## Output

Returns a structured list of detected admin-level events within the specified lookback window, including ownership transfer events (with old and new owners), proxy implementation upgrades (with old and new implementation addresses), and pause/unpause state changes — each timestamped and flagged for security review.
