# Agent Trust API – Base Contract Safety Audit

> Agent Trust API – Base Contract Safety Audit is a paid API for AI agents from agent-trust-api-production.up.railway.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Performs a comprehensive safety audit on a Base network token contract, checking for honeypot patterns, buy/sell taxes, ownership renunciation, hidden owners, mintability, proxy/upgrade risk, and liquidity lock status.

## 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 agent-trust-api-base-contract-safety-audit-de6034d4
```

Example prompt: Can you run a full safety audit on the Base token contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — check 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

Use this endpoint when you need to assess the safety of a specific Base network token or smart contract before trading, investing, or interacting. It is the right choice when you need honeypot detection, tax analysis, ownership checks, and liquidity status in a single call specifically for Base chain contracts. Prefer this over generic blockchain explorers when you need structured, agent-readable safety signals.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address not found on Base network returns empty/not-found result
- GoPlusLabs or Blockscout upstream service unavailable causes 502/503 error
- Rate limiting or payment failure (x402) if USDC payment is not processed
- Unverified or very new contracts may have 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 detailed safety report including: honeypot detection result, buy/sell tax percentages, ownership renounced status, hidden owner flag, mintability flag, proxy/upgrade risk indicator, liquidity lock status, and LP concentration metrics for the queried Base contract.
