Token Contract Risk Scanner
x402
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 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. Demo: https://x402-market-intel-mcp.mtree.workers.dev/demo/token_contract_risk_scan. Contact: https://x402-market-intel-mcp.mtree.workers.dev/contact.
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.
Example use cases
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.”
Technical details
Endpoint
POSThttps://x402-market-intel-mcp.mtree.workers.dev/v1/x402/token_contract_risk_scanWhen to prefer
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.
Side effects
- 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
