# x402.professorsausages.com Token Safety Check

> x402.professorsausages.com Token Safety Check is a paid API for AI agents from x402.professorsausages.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-29).

Performs a heuristic on-chain token contract safety analysis, returning a risk score, verdict, and specific red-flag indicators for a given token address on Base or Ethereum.

## 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 x402-professorsausages-com-token-safety-check-7de2a0ed
```

Example prompt: Can you run a heuristic token safety check on the Base chain for the contract at 0x4ed4e862860bed51a9570b96d89af5e1b0efefed — I want to know the risk score, verdict, and whether it has any red flags like minting, blacklisting, or an active owner?

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.02) heuristic safety screen of a token contract on Base or Ethereum before trading, investing, or integrating. Ideal for DeFi agents that need to flag obvious red flags (mint functions, blacklists, active owners) without a full audit. Not a substitute for professional audits or honeypot simulation.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unsupported chain slug returns an error
- Contract not deployed at address returns empty or error response
- Network RPC issues may cause delayed or failed reads
- v1 does not perform honeypot simulation, holder concentration, or LP lock checks — those appear in not_checked

## How this service works

Token safety & rug-pull/honeypot risk check — scans an ERC-20's bytecode & ownership on Base/Ethereum for mint, blacklist, pause, fee traps

## Output

Returns a JSON object with the chain, lowercased contract address, token metadata (name, symbol, decimals, totalSupply), an integer risk score from 0–100, a verdict of RISKY/CAUTION/NO_RED_FLAGS_FOUND, a flags object indicating mintable/can_blacklist/pausable/has_fee_setter/owner_renounced, human-readable reasons for the verdict, lists of checks run and not checked, the block height the data was anchored to, and a disclaimer about the heuristic nature of the results.
