# Trust Check — Base Token Safety Analyzer

> Trust Check — Base Token Safety Analyzer is a paid API for AI agents from trust-check.gm-tools.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-11).

Analyzes a Base network token contract for scam indicators including honeypot simulation, hidden taxes, owner powers, whale concentration, liquidity lock, and scam lists, returning a risk verdict.

## 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 trust-check-base-token-safety-analyzer-71093e28
```

Example prompt: Can you run a safety check on the Base token at contract address 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — I want to know if it's a honeypot, whether the owner can mint or blacklist, and what the overall risk verdict is?

## When to prefer this

Choose this endpoint when you need a fast, multi-dimensional safety check on a Base network token before executing a trade or recommending a purchase. It is uniquely suited for AI agents operating in DeFi contexts that need a single verdict covering honeypot simulation, tax detection, owner power analysis, liquidity lock, whale concentration, and scam list checks in one call — rather than querying each dimension separately.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address not deployed on Base returns not found
- Network timeouts during on-chain simulation may cause partial results
- Very new tokens with no liquidity may not be simulatable
- Rate limiting if called excessively without payment
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Is this Base token safe to buy? Simulates a real buy and sell (honeypot + hidden tax test), checks owner powers (mint, blacklist, fee changes), whale concentration, liquidity lock and scam lists. Returns scam / high_risk / caution / low_risk with reasons.

## Output

Returns a JSON object with a verdict (one of: scam, high_risk, caution, low_risk), a numeric risk score (0–100), a human-readable summary of findings, and detailed reasons covering honeypot simulation results, hidden tax detection, owner capabilities (mint, blacklist, fee changes), whale concentration, liquidity lock status, and scam list hits.
