## 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 tollbooth-token-safety-checker-02be6bd5
```

Example prompt: Before I swap into this token, can you run a Tollbooth safety check on the Solana token address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU and tell me the verdict and risk score?

## When to prefer this

Use Tollbooth when you need a fast, pre-trade safety signal on a specific Solana or EVM token before executing a swap. It is especially valuable for screening new or unaudited tokens for honeypot mechanics, freeze/mint authority abuse, blacklists, and hidden ownership — risks that standard price feeds and DEX APIs do not surface. Pair it with the /v1/swap/build safeMode flag to automatically block swaps on critical-risk tokens in an automated trading pipeline.

## Known failure modes

- Unknown token address returns verdict 'unknown' with no findings
- Unsupported chain value returns an error
- Invalid or malformed token address causes request failure
- Token with no on-chain data may return unknown verdict
- Rate limiting or payment failure returns 402 or 429 error
- Network timeout for slow chain RPC responses

## How this service works

Is this token safe to buy? Check any Solana or EVM token for rug pull and honeypot risk before you swap. Solana: mint/freeze authority, Token-2022 transfer hooks, permanent delegates - read on-chain. EVM (Base, Ethereum, Arbitrum, Polygon, Optimism, BSC, Avalanche): honeypot, sell tax, blacklists, hidden owners, mintability. Verdict (ok/warn/critical/unknown), 0-100 risk score, itemized findings. Pair with POST /v1/swap/build safeMode to refuse critical-risk swaps.

## Output

Returns a JSON object with the chain, token address, a verdict enum (ok/warn/critical/unknown), an integer risk score from 0 to 100 (higher is riskier), and an array of itemized findings each with an id, severity (info/warn/critical), and detail string explaining the specific risk detected. Also includes a checkedAt timestamp and optional source field.
