# Token Risk Check – Deployer History & Rug Verdict

> Token Risk Check – Deployer History & Rug Verdict is a paid API for AI agents from onchaincheck.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-30).

Looks up a token deployer's full launch history and returns a rug-pull risk verdict (repeat-rugger, prior-rug, serial-launcher, clean-so-far, too-new) with per-token risk scores and liquidity survival data at 24h and 7d.

## 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 token-risk-check-deployer-history-rug-verdict-179c89dc
```

Example prompt: Can you check if the deployer of this Solana token 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU has a history of rugging — I want to know their verdict and whether they've pulled liquidity on past tokens.

## When to prefer this

Use this endpoint when you need a historical track record of a token deployer rather than just a point-in-time risk score for a single token. It is the right choice when assessing whether a wallet is a serial rugger across multiple launches, or when you want to know if liquidity actually survived 24h and 7d on prior tokens. Prefer this over single-token risk checks when performing deployer-level due diligence before buying into a new launch.

## Known failure modes

- Invalid address format — address doesn't match EVM (0x…) or base58 Solana pattern
- Token address provided but deployer lookup fails — contract may be unverified or not indexed
- No launch history found — deployer has no tokens recorded since 2026-10-23 (too-new verdict)
- Unsupported chain specified — must be one of base, eth, arbitrum, optimism, polygon, solana
- Payment failure — x402 micropayment of $0.005 USDC not completed or rejected
- Rate limit or server error — 5xx response

## How this service works

Who launched this token, and what happened to their other tokens? A creator's launch record on Base, Ethereum, Arbitrum, Optimism, Polygon or Solana from our own history of new pools: every token the wallet launched since 2026-10-23 with its risk score at launch and whether its liquidity was gone 24 hours and 7 days later, plus a verdict (repeat-rugger, prior-rug, serial-launcher, clean-so-far, too-new). Pass the deployer wallet or a token address. Not advice.

## Output

Returns the deployer wallet address, a list of every token they launched since 2026-10-23 with each token's risk score at launch, whether liquidity was present 24 hours later, whether liquidity survived 7 days, and a summary verdict label: repeat-rugger, prior-rug, serial-launcher, clean-so-far, or too-new.
