## 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 nojunk-safety-gate-token-safety-check-1fe0c787 -d '<json body>'
```

Example prompt: Before I buy any BRETT tokens, run a safety check on the token contract 0x532f27101965dd16442E59d40670FaF5eBB142E4 on Base and tell me if it's safe to proceed.

## When to prefer this

Use this endpoint specifically when an agent needs a fast, pre-transaction safety gate on a token contract address before executing a buy or swap. It is ideal for autonomous DeFi agents, trading bots, or wallet assistants that need a structured ALLOW/CAUTION/BLOCK verdict with a reason before committing funds — especially in x402 payment flows where the agent acts autonomously.

## Known failure modes

- Invalid or malformed token address returns an error
- Unsupported chain value causes rejection
- Token address not found on specified chain may return CAUTION or error
- Network timeout from third-party security database lookups
- New or very obscure tokens may have insufficient data for a confident verdict

## How this service works

Yes/no safety verdicts an agent runs before it acts: before sending funds (/wallet), buying a token (/token), opening a link (/site) or paying an x402 seller (/x402). Every answer has safe (true/false), verdict (ALLOW, CAUTION, BLOCK) and a one-line reason.

## Output

A JSON object with: safe (boolean), verdict (ALLOW, CAUTION, or BLOCK), a one-line human-readable reason, a list of flags (empty if clean), the token address and chain checked, the timestamp of the check, and a legal disclaimer clarifying the automated nature of the screen.
