Prompt injection detection: is this text a trap for your AI agent? Checks a web page, email, tool result, API answer or another agent's message before your agent acts on it: does it try to make the agent ignore its instructions, pay or send money, hand over keys or private data, or obey a fake user, admin or support message?

Call it from code

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://presign-guard.fizzl.eu/v1/injection", { method: "POST" });
console.log(await res.json());
