## 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 hergert-synthora-tokenguard-erc-20-token-safety-analyzer-9ff173a7 -d '<json body>'
```

Example prompt: Before I ape into this token, can you run a safety check on contract 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base — is it a honeypot and what's the sell tax?

## When to prefer this

Choose this endpoint when an agent or user needs a quick, automated safety check on an ERC-20 token contract before executing a trade or recommending an investment. It is especially useful for DeFi trading bots, portfolio assistants, and token research agents that need to screen for honeypots and sell taxes on Base, Ethereum, BSC, or Polygon without building custom on-chain analysis.

## Known failure modes

- Invalid or non-existent contract address returns an error or inconclusive verdict
- Unsupported chain identifier causes a validation error
- Token contract not yet indexed or too newly deployed may return incomplete signals
- Network RPC timeouts may cause delayed or failed responses
- Tokens with obfuscated proxy contracts may yield incomplete honeypot detection

## Output

Returns a JSON object with a boolean ok flag, a niche label ('tokenguard'), and a result object containing the chain, token address, a list of human-readable reason strings explaining the verdict, a signals object (honeypot boolean, sell_tax_pct numeric), and a string verdict such as 'SAFE' or 'UNSAFE'.
