# Crucible Token Security Audit

> Crucible Token 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 2026-09-16).

Audits an ERC-20 token contract address on Ethereum mainnet for security risks, returning risk scores, flags, verification status, and cited evidence.

## 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-token-security-audit-2e565e2b -d '<json body>'
```

Example prompt: Can you run a security audit on this Ethereum token contract — 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 — and tell me if it's verified, any risk flags, and the overall risk score?

## When to prefer this

Choose this endpoint when you need a structured, evidence-backed security audit of a specific ERC-20 token on Ethereum mainnet, especially when you need cited sources and a machine-readable risk score for automated decision-making. Prefer it over generic blockchain explorers when you need actionable security flags and confidence scores rather than raw contract data.

## Known failure modes

- Invalid or non-Ethereum contract address returns an error or empty result
- Non-mainnet addresses (e.g. testnets) may not be supported
- Newly deployed contracts may have insufficient data for confident scoring
- Payment failure via x402 protocol blocks the call
- Token with no on-chain activity may return low-confidence results

## 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 a structured security report including: a numeric risk score (0–1), confidence score, array of security flags (e.g. honeypot, unverified, mintable), token type, contract verification status, cited evidence claims with source URLs and content hashes for auditability.
