# Token Risk Checker (Quick Screen)

> Token Risk Checker (Quick Screen) is a paid API for AI agents from checker-production-40a5.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Performs a fast on-chain risk screen of a Base network token contract, returning a 0-100 risk score, risk level, and per-check pass/warn/fail results covering liquidity, honeypot, taxes, mint powers, proxies, and more.

## 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-checker-quick-screen-25c83075
```

Example prompt: Can you do a quick risk screen on this Base token at 0x1234567890abcdef1234567890abcdef12345678 and tell me the risk score, level, and any red flags like honeypot, hidden taxes, or mint powers?

## When to prefer this

Choose this quick screen endpoint over the full report endpoint when you need low-latency, cost-efficient token screening at scale — such as in a trading bot or automated pipeline that evaluates many tokens per minute. At $0.01 per call it is priced for high-frequency bot usage. Skip this in favor of the full report when you need a human-readable AI summary or are doing a one-off deep-dive on a specific token.

## Known failure modes

- Invalid or malformed contract address returns a 400 error
- Contract address not found on Base returns an error or empty result
- Network/RPC issues may cause timeouts for very recently deployed contracts
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Non-Base chains (only Base is supported) will be rejected or default to Base

## How this service works

Fast Base token risk screen, same checks as the full report without the AI summary: creator-pullable liquidity (incl. Uniswap V4), copycat tickers, honeypot and taxes, mint/pause/blacklist powers, upgradeable proxy, ownership, launch platform (Clanker/Doppler/B20) and holders. Returns a 0-100 score, LOW/MEDIUM/HIGH level and pass/warn/fail reasons per check. Priced for bots that screen every token.

## Output

Returns a JSON object containing a numeric risk score from 0 to 100, a categorical risk level (LOW, MEDIUM, or HIGH), and an array of individual check results each labeled pass, warn, or fail. Checks cover creator-pullable liquidity (including Uniswap V4 hooks), copycat tickers, honeypot detection, buy/sell taxes, mint/pause/blacklist admin powers, upgradeable proxy status, ownership renouncement, launch platform identification (Clanker, Doppler, B20), and top holder concentration.
