## 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 fiatdock-token-safety-check-03fbb220
```

Example prompt: Before I ape into this token, can you run a full safety check on contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — I want to know if it's a honeypot, what the buy/sell taxes are, whether the owner has mint or blacklist powers, and an overall verdict?

## When to prefer this

Use this endpoint when you need a fast, structured, pay-per-call safety verdict on an EVM token before trading, recommending, or listing it. Prefer this over generic block explorers when you need a machine-readable safe/caution/danger verdict with specific risk signals (honeypot, taxes, owner powers, holder concentration) in a single call. If you also need price data bundled in, consider the sibling 'Token report' endpoint which combines price, liquidity, and safety in one call.

## Known failure modes

- Upstream GoPlus or DexScreener data unavailable — returns HTTP 4xx, no charge applied
- Invalid or malformed contract address — returns error without verdict
- Token not indexed by DexScreener — liquidity data may be missing or zero
- Very new token with no on-chain history — limited data may reduce verdict accuracy
- Network/chain not supported — endpoint may return error for non-EVM or unsupported chains

## How this service works

Token safety & rug check — on-chain honeypot/tax/owner-privilege/holder-concentration risk verdict for any EVM token (GoPlus + DexScreener). Pay-per-call via x402. An empty body is answered for USDC on Base (the x402 settlement asset); send {"token":"0x…"} for any other token.

## Output

A JSON object containing the token's name and symbol, an overall verdict of 'safe', 'caution', or 'danger', a human-readable verdictReason, a boolean isHoneypot flag, buyTaxPct and sellTaxPct, holderCount, topHolderPct (concentration of top holders), liquidityUsd, isOpenSource flag, and a risks array listing any specific detected risk factors. Returns HTTP 400+ without charging when upstream security data is unavailable.
