Scans untrusted text, HTML, email, document text, API responses, and tool outputs for prompt injection, credential theft, data exfiltration, tool manipulation, and other instructions that could compromise an autonomous AI agent.

Transaction Preflight
Simulates an unsigned Base or Base Sepolia EVM transaction with read-only RPC calls before an agent signs or broadcasts it. Returns execution/revert status, gas estimate, decoded top-level ERC-20 transfers and approvals, unlimited-approval warnings, and a risk signal. It never signs, holds keys, or broadcasts. Standard RPC does not expose complete internal/token state diffs.

URL Safety Gate
Paid URL preflight check ($0.005 USDC): assess URL syntax, transport, host/IP, suspicious patterns, and at most five HTTPS redirects without fetching page content. Blocks local/private destinations. Optional Google Web Risk threat intelligence is used only if configured; otherwise results are explicitly heuristic-only and degraded. This is a risk signal, not a guarantee that a URL is safe.

Wallet Risk Check
Checks a public Base wallet or contract address for counterparty risk before an autonomous agent sends funds, accepts payments, grants approvals, or interacts with it. Returns on-chain account metadata, machine-readable risk signals, confidence, and a conservative recommendation. Sanctions and malicious-address matches are unknown unless a trusted intelligence provider is configured. Never send private keys or seed phrases.
