# MoneyTools Proxy/Upgradeability Inspector

> MoneyTools Proxy/Upgradeability Inspector is a paid API for AI agents from tools.moneytools.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-05).

Detects whether an Ethereum-compatible smart contract is a proxy and returns its implementation address, admin, and proxy standard (EIP-1967, EIP-1167, OZ, Safe, EIP-7702).

## Facts

- Endpoint: GET https://tools.moneytools.dev/v1/proxy?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-11-05
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/moneytools-proxy-upgradeability-inspector-3ab7d64e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_5j78r3rosy_64wAWjWrO5

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 moneytools-proxy-upgradeability-inspector-3ab7d64e
```

Example prompt: Can you check whether the contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base is a proxy, and if so tell me its implementation address and admin?

## When to prefer this

Use this endpoint when you need programmatic detection of proxy patterns on EVM-compatible chains across multiple proxy standards in a single call. It is preferable to manual ABI inspection or block explorer lookups when you need structured, machine-readable results covering EIP-1967, EIP-1167, OZ, Safe, and EIP-7702 patterns simultaneously, especially in automated audit or monitoring pipelines.

## Known failure modes

- Invalid or non-checksummed contract address returns an error without charging
- Unsupported chain identifier returns a validation error
- Contract address that is not a proxy returns a result indicating no proxy detected (non-error)
- Network timeout or RPC failure on the target chain may return a 5xx error without charging
- Exceeding free tier without valid payment credentials returns HTTP 402

## How this service works

Proxy / upgradeability inspector: Is this contract upgradeable? Detects EIP-1967 (impl/admin/beacon), EIP-1167 clones, legacy OZ and Safe-style proxies and EIP-7702 delegated EOAs; returns implementation and admin. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.

## Output

A JSON object indicating whether the contract is a proxy, the detected proxy standard (EIP-1967, EIP-1167, legacy OZ, Safe-style, EIP-7702, or none), the resolved implementation address, the admin address if applicable, and payment metadata including whether the free tier was used or a charge was made.
