# Token Contract Risk Scanner

> Token Contract Risk Scanner is a paid API for AI agents from x402-market-intel-mcp.mtree.workers.dev, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-15).

Scans an EVM token/contract address for bytecode-level risks, high-risk function selectors, proxy/admin patterns, and ERC-20 metadata, returning a pay/avoid/manual-review verdict for agent spending decisions

## 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-contract-risk-scanner-98166b57 -d '<json body>'
```

Example prompt: Before my agent spends any USDC on this token, scan the contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Base and tell me whether I should pay, avoid, or manually review it — I want to see the bytecode risk flags, any proxy or admin hints, and the overall verdict.

## When to prefer this

Use this endpoint when an AI agent needs to evaluate whether a token contract is safe to interact with before committing funds — particularly in automated DeFi workflows, agentic payment pipelines, or any scenario where the agent must decide to pay/avoid without human review. Prefer over generic blockchain explorers when you need a structured, machine-readable verdict rather than raw explorer data.

## Known failure modes

- Invalid or non-existent contract address returns error or empty result
- Non-EVM or unsupported chain address causes lookup failure
- Contract with no bytecode (EOA address) returns no analysis
- Network timeout or RPC failure when fetching on-chain data
- Payment failure via x402 (insufficient USDC balance or misconfigured payment header) blocks the call

## How this service works

Token/contract risk scan inspired by the top x402 earner: contract bytecode, ERC-20 metadata, high-risk function selectors, proxy/admin hints, and a pay/avoid/manual-review score for agent spend. Price 0.25 USDC on Base via x402. Free preview: https://x402-market-intel-mcp.mtree.workers.dev/preview/token_contract_risk_scan?source=x402_manifest.

## Output

Returns a structured risk report including: ERC-20 metadata (name, symbol, decimals), contract bytecode analysis, detected high-risk function selectors (e.g. mint, pause, blacklist), proxy/admin pattern hints, and a final verdict of 'pay', 'avoid', or 'manual-review' to guide agent spend decisions.
