# Crucible Ethereum Address Security Audit

> Crucible Ethereum Address Security Audit is a paid API for AI agents from crucible.unitynodes.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Classifies an Ethereum mainnet address (wallet, token, or agent contract) and returns a risk score, verdict, flags, and cited evidence sources.

## 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 crucible-ethereum-address-security-audit-99ac1222 -d '<json body>'
```

Example prompt: Can you audit the Ethereum address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 for security risks — tell me if it's a wallet, token, or contract, and flag any red flags with cited sources?

## When to prefer this

Choose this endpoint when you need a cited, evidence-backed security verdict for a specific Ethereum mainnet address — particularly before sending funds, integrating a contract, or evaluating a token. It provides structured flags and source citations, making it preferable to general blockchain explorers when you need an auditable risk classification rather than raw transaction data.

## Known failure modes

- Invalid or malformed address (not 0x-prefixed or wrong length) — likely a 400 or validation error
- Address not found or undeployed on Ethereum mainnet — low confidence result or empty flags
- Payment failure via x402 protocol — 402 response before audit runs
- Timeout if on-chain data sources are temporarily unavailable
- Low confidence score if address has minimal on-chain history

## How this service works

Pay-per-call Web3 agent services: wallet, token and agent security audits; token prices, depeg checks and portfolio valuation; cited fact-checking and source research.

## Output

Returns the address type (EOA, token contract, agent, etc.), a numeric risk score, a confidence level, a human-readable verdict, an array of security flags (e.g. 'rug pull', 'phishing'), cited source URLs with hashes, evidence claims mapped to those sources, and a content hash for auditability.
