# YieldProbe Token Security Check

> YieldProbe Token Security Check is a paid API for AI agents from yieldprobe.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-10).

Returns a contract-level security risk summary for a DeFi token, including honeypot detection, tax rates, mintability, proxy status, owner powers, and holder concentration.

## 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 yieldprobe-token-security-check-a42beb3a
```

Example prompt: Can you run a security check on the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on chain 8453 and tell me if it's a honeypot, whether it has dangerous owner powers, and what the buy/sell taxes are?

## When to prefer this

Use this endpoint when you need fast, per-token security due diligence before executing a trade or adding a token to a watchlist — especially for newly deployed or lesser-known contracts. Prefer it over general DeFi pool endpoints when the question is about contract-level safety rather than yield or APY.

## Known failure modes

- Invalid chainId returns an error or empty response
- Contract address not found on the specified chain returns no data
- Unsupported chain returns an error
- Malformed address format returns a validation error
- Rate or payment failure (x402) returns a 402 response requiring USDC payment on Base

## How this service works

Pay-per-call DeFi intelligence API for AI agents over x402: yields, APY anomalies, stablecoin pegs, token risk. USDC on Base.

## Output

A structured risk summary for the specified token contract, covering: honeypot detection result, buy and sell tax percentages, whether the contract is mintable or uses a proxy pattern, extent of owner/admin privileges, and holder concentration metrics — enabling a go/no-go risk decision before interacting with the token.
