# Gnosis Safe Multisig Inspector

> Gnosis Safe Multisig Inspector is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-13).

Inspects a Gnosis Safe multisig wallet on Base, Ethereum, Arbitrum, Optimism, or Polygon, returning owners, signature threshold, nonce, version, modules, and security warnings.

## Facts

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 gnosis-safe-multisig-inspector-d6c426b6 -d '<json body>'
```

Example prompt: Can you inspect the Gnosis Safe at 0x849D52316331967b6fF1198e5E32A0eB168D039d on Ethereum and tell me who the owners are, what the signing threshold is, and whether there are any security warnings?

## When to prefer this

Use this endpoint when you need a quick, structured audit of a Gnosis Safe multisig configuration across Base, Ethereum, Arbitrum, Optimism, or Polygon — especially when security warnings (single-signer risk, bypassing modules) are needed. Prefer this over manually querying on-chain data or block explorers when you need a normalized, parsed response including the M-of-N scheme and module analysis in a single call.

## Known failure modes

- Invalid or non-existent Safe address returns an error or null fields
- Unsupported network returns a validation error on the 'red' enum field
- Malformed address format causes a request rejection
- Safe deployed on a network other than the five supported chains returns no data
- Rate limiting or payment failure returns a 402 or 429 error

## How this service works

Inspect a Safe (Gnosis Safe) multisig on Base, Ethereum, Arbitrum, Optimism or Polygon: owners, signature threshold (M of N), nonce, version and enabled modules, with warnings (single-signer, modules that bypass owners).

## Output

Returns a JSON object with the Safe's address, network, list of owner addresses, numeric threshold, M-of-N scheme string (e.g. '3 de 6'), current nonce, Safe contract version, array of enabled modules, a block explorer URL, and an array of security warnings such as single-signer risk or modules that bypass owner signatures.
