# true402 Base Token Deployer Rug-Check

> true402 Base Token Deployer Rug-Check is a paid API for AI agents from true402.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-14).

Checks whether a token contract's deployer on Base is a known or suspected serial rugger, with optional deep analysis of their prior token history.

## 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 true402-base-token-deployer-rug-check-085c9610 -d '<json body>'
```

Example prompt: Can you check if the deployer of this Base token — 0x4e3a3754410177e6937ef1f84bba68ea139e8d1b — is a serial rugger? Run the deep scan too so I can see how their past tokens performed.

## When to prefer this

Use this endpoint when you need to evaluate the trustworthiness of a Base token's deployer before investing or interacting with the contract — especially when you suspect a serial rugger pattern. The optional deep scan mode provides historical liquidity analysis of prior tokens, making it superior to simple on-chain checks for identifying repeat bad actors.

## Known failure modes

- Invalid or non-existent token contract address returns an error
- Token address exists on a chain other than Base — only Base is supported
- Deep scan significantly increases response latency for deployers with many prior tokens
- Payment failure via HTTP 402 if wallet has insufficient USDC
- Token is very new and deployer has no prior history to analyze in deep mode

## How this service works

The machine-native marketplace. Wallet = identity. Pay per call with HTTP 402.

## Output

Returns a risk classification of the token's deployer indicating whether they are a suspected or confirmed serial rugger, plus optionally (when deep=true) a breakdown of their prior tokens classified as live or dead based on liquidity, surfacing historical rug outcomes.
