## 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 canaryguard-base-token-honeypot-tax-auditor-c243cccb
```

Example prompt: Can you audit the Base token at contract address 0x4200000000000000000000000000000000000006 and tell me if it's a honeypot, what the buy and sell taxes are, how deep the liquidity is, and whether the metadata contains any prompt injection traps?

## When to prefer this

Choose this endpoint when you need a rapid, pre-trade safety check on a Base ERC-20 token — especially for DeFi bots, trading agents, or investor workflows that need to screen for honeypot mechanics, hidden taxes, and AI-specific threats like prompt injection in token metadata. It is specifically tuned for Base network tokens and combines multiple risk signals (honeypot, tax, liquidity, metadata injection) in a single call, making it more efficient than querying separate on-chain data sources.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Token not deployed on Base mainnet causes lookup failure
- Very new tokens with no liquidity may return incomplete tax or depth data
- Rate limiting or payment failure (402) if USDC payment is not properly attached
- Token with obfuscated proxy patterns may yield inconclusive honeypot assessment
- Network congestion or RPC unavailability may cause timeout errors

## How this service works

Audits Base ERC-20 token contracts for honeypot risks, buy/sell transfer taxes, liquidity depth, and prompt injection traps in token metadata.

## Output

Returns a structured risk assessment for the specified Base ERC-20 token, including a honeypot risk flag, buy/sell/transfer tax percentages, liquidity depth metrics, and any detected prompt injection or malicious content embedded in the token's on-chain metadata.
