## How to call it through Zero

```sh
zero fetch --capability agent-trust-contract-safety-audit-b41dfd6f
```

Example prompt: Can you run a full safety audit on this Base token contract 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — I want to know if it's a honeypot, whether ownership is renounced, what the buy/sell taxes are, and if the liquidity is locked?

## When to prefer this

Choose this endpoint when you need a comprehensive on-chain security audit of a specific Base token or contract before trading, investing, or integrating it — especially when you need honeypot detection, tax analysis, and liquidity lock status in a single call. Prefer this over general blockchain explorers when you need pre-parsed risk signals rather than raw contract data.

## Known failure modes

- Invalid or non-existent contract address returns error
- Contract not deployed on Base network returns not found
- GoPlusLabs or Blockscout upstream unavailability causes timeout or partial data
- Rate limiting or payment failure (x402) blocks the request
- Unverified contracts may return incomplete audit data

## How this service works

Contract safety audit for any Base token/contract. Checks honeypot patterns, buy/sell taxes, ownership status (renounced?), hidden owner, mintability, proxy/upgrade risk, liquidity lock status, and LP concentration. Powered by GoPlusLabs + Blockscout.

## Output

Returns a structured safety report for the given contract address including: honeypot detection result, buy and sell tax percentages, whether contract ownership is renounced, hidden owner detection, mintability flag, proxy/upgrade risk indicator, liquidity lock status, and LP concentration metrics — all sourced from GoPlusLabs and Blockscout.
