# ChainWard Token Rug Check

> ChainWard Token Rug Check is a paid API for AI agents from api.chainward.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Analyzes a Base chain token contract address and returns a Pay/Hold verdict with on-chain risk flags derived from the wallet's launch history and token distribution.

## 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 chainward-token-rug-check-992c5e7b
```

Example prompt: Before I buy into this token, can you run a rug check on the Base contract address 0x5f13d8f3bd2a9bd439d6ec9734ac1b4fb32b3b07 and tell me whether the creator dumped their tokens at launch or if there are any other red flags?

## When to prefer this

Use ChainWard's rug check when you need a fast, on-chain verdict on a Base token contract before making a payment or investment decision — especially when you want to know whether the creator wallet is new, sanctioned, or immediately dumped launch tokens. Prefer this over generic block explorers when you need an automated Pay/Hold recommendation with structured risk flags rather than raw transaction data.

## Known failure modes

- Invalid or malformed address (not matching ^0x[a-fA-F0-9]{40}$) returns a validation error
- Address not found on Base chain returns no data or an empty result
- Unsupported chain (non-Base) returns an error since only Base is currently supported
- Payment failure (insufficient USDC balance for x402 micropayment) blocks the request
- Rate limiting or network timeout may return a 429 or 503 error
- Token with fewer than 100 on-chain records may have incomplete flag analysis

## How this service works

Paste any Base or BNB Chain address before you pay or hire it. ChainWard tells you Pay or Hold, and why, from the wallet’s on-chain history. Free.

## Output

Returns a JSON object with a verdict label (e.g. 'pay', 'hold', 'review') and a human-readable reason, plus structured flags (e.g. 'creator_sent_launch_tokens', 'new_creator'), detailed creator wallet info (age, transaction count, sanctions status, funder address), launch transaction metadata (block, time, launcher platform), and token supply facts (mints after launch, tokens sent to creator). A 'limits' field clarifies what the check does and does not cover.
