Wren Pre-sign Check
Wren Pre-sign Check is a pay-per-call x402 API that an AI agent calls before it signs anything with its wallet. Send a transaction (to + data), an EIP-712 typed-data payload or untrusted text, and it returns block, review or allow, the decoded call in plain words and every finding: unlimited approvals, Permit and Permit2 signatures, setApprovalForAll, EIP-7702 delegation, contract deployment and injected instructions. With an optional wren-guard policy (allowlist, spenders, caps) it also blocks unknown recipients, over-cap amounts and lookalike addresses. It is a static check and stores nothing you send; free demos show real output.
Added
Wren x402 Doctor
Wren x402 Doctor helps sellers of x402 pay-per-call endpoints, the payment standard AI agents use to pay for APIs in USDC, get listed in the Coinbase CDP Bazaar and stay listed. A free lint checks a 402 response against the x402 v2 spec and the Bazaar listing rules (networks, amounts, payTo checksum, description length, injection-like text, schema and metadata), and now also checks a seller's OpenAPI and x402 discovery documents. A paid health check returns every Bazaar listing for your wallet address with 30-day calls, unique payers and an estimated delisting date, and a paid market check (GET /market) returns up to 20 comparable live Bazaar listings with USD price, 30-day calls and payers, plus price quartiles.
Added
wren-guard Pro
wren-guard Pro is a TypeScript guard library for AI agents that hold or move funds on Base and other EVM chains (viem, CDP AgentKit, Privy, Eliza and similar stacks). It enforces allowlisted, capped and simulated sends, decodes calldata and signatures to flag unlimited approvals, Permit, Permit2, setApprovalForAll and EIP-7702 delegation, screens for injected instructions and watches nonces. It ships with an 89-scenario attack corpus drawn from public agent wallet incidents and a GitHub Action that fails CI if your agent's policy would let a known attack through. The original Python wren-guard is free and MIT licensed.
