## 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 api-x402node-dev-f1317a2f
```

Example prompt: Before I buy this token, can you run a safety check on the ERC20 contract at 0x4200000000000000000000000000000000000006 on Base and tell me the risk score and whether it's safe — specifically if it has mint functions, a blacklist, or if ownership is still active?

## When to prefer this

Use this endpoint when an AI trading agent or DeFi automation needs pre-transaction due diligence on an unknown ERC20 token on Base L2. Prefer this over generic contract explorers when you need a structured risk score and specific rug-pull indicators (honeypot patterns, mint authority, blacklist functions) without building your own bytecode scanner.

## Known failure modes

- Invalid or non-existent contract address returns an error
- Contract not deployed on Base mainnet causes lookup failure
- Non-ERC20 contract address may return incomplete analysis
- Network timeout from RPC provider
- Payment failure if USDC balance insufficient for $0.10 fee

## How this service works

Token safety check before buying or interacting: given an ERC20 contract on Base, returns risk_score 0-100 and verdict. Scans bytecode for dangerous functions (mint, blacklist, pausable transfers, adjustable fees), checks ownership renounced vs active, ERC20 interface completeness, and supply concentration. Red flags surface honeypot/rug indicators. For AI trading agent pre-transaction due diligence, automated token vetting, rug-pull avoidance.

## Output

Returns a risk_score between 0 and 100 and a verdict (safe/risky/dangerous), along with flags for dangerous bytecode patterns such as mint, blacklist, pausable transfers, and adjustable fees, plus ownership renouncement status and supply concentration metrics.
