# DeFi Admin-Change Feed: Proxy Upgrades, Ownership & Pause Events

> DeFi Admin-Change Feed: Proxy Upgrades, Ownership & Pause Events is a paid API for AI agents from admin-watch.quietworklabs.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Returns a live risk verdict for a DeFi contract address, including proxy upgrade history, ownership structure, pause authority, and role changes across 85 protocols on Ethereum, Base, Arbitrum, and Optimism.

## 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 defi-admin-change-feed-proxy-upgrades-ownership-pause-events-e60da941
```

Example prompt: Check the admin risk verdict for the contract 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 on Base — I want to know if it's an upgradeable proxy, who controls upgrades, and whether there are any high-severity admin findings.

## When to prefer this

Choose this endpoint when you need structured, pre-indexed admin risk intelligence for DeFi contracts across Ethereum, Base, Arbitrum, and Optimism — particularly proxy upgrade history, ownership authority type, and pause mechanisms. It covers 911 contracts across 85 protocols, so it is far faster and cheaper than running your own on-chain indexing. Prefer it over raw RPC calls or block explorers when you need a parsed risk verdict rather than raw event logs, and when the contract is likely to be in its curated watchlist.

## Known failure modes

- Contract address not in the monitored set of 911 contracts — returns no data or a 404-style error
- Invalid or malformed contract address — request rejected
- Chain not supported or not specified correctly — may return empty or error
- Payment not settled via x402 protocol — request blocked with 402 Payment Required
- Transient upstream node or indexing outage — may return stale or partial data

## How this service works

Live feed of proxy upgrades, ownership transfers, pauses and role changes across 911 contracts of 85 DeFi protocols on Ethereum, Base, Arbitrum and OP.

## Output

Returns a JSON object containing: a risk level (e.g. low/medium/high), the chain, proxy type (e.g. oz-legacy), current implementation address, upgrade authority type (e.g. EOA or multisig), full upgrade history with transaction hashes and timestamps, a plain-English summary of admin risk, and a list of findings each with severity and descriptive text.
