Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 onchainpulse-evm-token-safety-scanner-a28c3247
```

Example prompt: Before I buy, can you run a full honeypot and rug-pull safety scan on this Base token at contract address 0x1234...abcd — I need to know the buy/sell tax, whether LP is locked, if there are any blacklist or mint risks, and what the final CLEAR/CAUTION/AVOID verdict is?

## When to prefer this

Use this endpoint when an EVM trading agent needs a fast, comprehensive pre-trade safety check on a token contract across Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, or Avalanche — especially when you need honeypot simulation, tax detection, and LP lock status fused into a single actionable verdict rather than querying multiple separate tools.

## Known failure modes

- Invalid or unrecognized contract address returns error
- Unsupported chain ID returns chain-not-supported error
- Token with no liquidity may return incomplete analysis
- Very new or unindexed token may lack holder/LP data
- Rate limit or payment failure returns 402 or 429 error

## How this service works

Honeypot, rug & token-safety scanner for Base & EVM tokens — instant pre-trade check: sell-simulation honeypot, buy/sell tax, mint, upgradeable proxy, pausable transfers, blacklist, owner privileges, LP lock/burn, holder concentration, fused with live liquidity & flow into one CLEAR / CAUTION / AVOID verdict. Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, Avalanche. For EVM trading agents.

## Output

Returns a structured safety report including: honeypot sell-simulation result, buy and sell tax percentages, mint authority flag, upgradeable proxy flag, pausable transfers flag, blacklist flag, owner privilege details, LP lock/burn status, holder concentration metrics, live liquidity data, token flow analysis, and a final aggregated verdict of CLEAR, CAUTION, or AVOID.
