SiteCheck Agent Intel & Dev

Screens one text for prompt-injection patterns in English (instruction override, role or system-prompt extraction, jailbreak personas, hidden or encoded instructions) using a fixed rule list based on OWASP LLM01 categories. Returns HIGH/MEDIUM/LOW/NONE, each match, and the text with matches removed. A rule list misses rewording and other languages: treat NONE as no known pattern, not as safe.

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://api.fadeandco.workers.dev/api/agent-intel/prompt-injection-firewall", { method: "POST" });
console.log(await res.json());
