# Vextorium ERC-20 Admin Control Checker

> Vextorium ERC-20 Admin Control Checker is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-11).

Analyzes an ERC-20 token contract to detect owner privileges, upgradeable proxy patterns, mint/pause/blacklist/fee-setting functions, and reports the issuer's administrative control level.

## 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 vextorium-erc-20-admin-control-checker-713144ab -d '<json body>'
```

Example prompt: Can you check the admin control level of the token contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — specifically whether the owner can blacklist addresses, pause the contract, or mint new tokens, and whether ownership has been renounced?

## When to prefer this

Use this endpoint when you need to programmatically assess issuer control risks for any ERC-20 token on Base, Ethereum, Arbitrum, Optimism, or Polygon — especially before investing in or integrating a token, auditing DeFi protocols for centralization, or building token risk dashboards. It is not a scam detector but a precise, code-level admin-privilege scanner.

## Known failure modes

- Invalid or non-existent contract address returns an error or null fields
- Unsupported network causes a validation error (only base, ethereum, arbitrum, optimism, polygon accepted)
- Contract is not an ERC-20 token may return empty or partial findings
- Network RPC unavailability may cause timeout or degraded response
- Proxy contracts with obfuscated logic may yield incomplete findings

## How this service works

ERC-20 admin-control check: detects owner privileges, upgradeable proxy, mint, pause, blacklist and fee-setting functions in the contract code. Measures issuer control, not a scam verdict.

## Output

Returns a JSON object with the token name, symbol, contract address, network, owner address, whether ownership has been renounced, whether the contract is an upgradeable proxy, a list of detected admin capabilities (e.g. 'Can block addresses (blacklist).'), and an overall administrative_control_level rating (e.g. 'high', 'medium', 'low'), plus an explanatory note.
