## 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 erc-20-token-risk-flags-on-chain-facts-base-auditor-x402-459fa30c -d '<json body>'
```

Example prompt: Can you check the risk flags for the token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I want to know if it's a honeypot, has high tax, is mintable, or has any other red flags, plus the on-chain symbol and supply.

## When to prefer this

Use this endpoint when you need a quick, automated risk-flag screen for any ERC-20 token on Base before a trade, investment decision, or portfolio inclusion. It combines GoPlus's curated threat intelligence (honeypot detection, tax checks, ownership analysis) with live on-chain data in a single call. Prefer this over manual block explorer lookups or generic contract analysis when you need structured, machine-readable flags for a Base-specific token. Not a substitute for a full smart contract audit; use it as a first-pass filter.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty flags
- Token not indexed by GoPlus returns partial or missing risk data
- Network or RPC timeout on Base mainnet results in a service error
- Undeployed or self-destructed contract address may return empty results
- GoPlus rate limits or outages may cause upstream failures

## How this service works

Risk flags for an ERC-20 on Base (honeypot, tax over 10%, mintable, unverified source, hidden owner, pausable...) from GoPlus plus on-chain facts (symbol, supply, owner). No safety verdict: no flags is not a guarantee.

## Output

Returns a structured object containing GoPlus-sourced boolean risk flags (honeypot detected, sell/buy tax over 10%, mintable, unverified contract source, hidden owner, pausable) alongside on-chain facts read directly from Base mainnet: the token's symbol, total supply, and current owner address. No overall safety verdict is provided — absence of flags is not a guarantee of safety.
