SIWE Signature Verifier: Verify a Sign-In-With-Ethereum (EIP-4361) signature. Stateless oracle: checks the signature against the message and returns the wallet address + chainId. Never mints sessions or consumes nonces. Get a checksummed address first via wallet_checksum. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/wallet_verify_siwe.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
