Integration example
agent.ts — pay per audit
// Any agent that speaks HTTP can call this
import { x402Fetch } from "@x402/fetch";

const result = await x402Fetch(
  "https://hub.fronesislabs.com/x402/dcl_verify",
  {
    method: "POST",
    body: JSON.stringify({
      code: "<your smart contract>",
      agent_id: "my-agent-v1"
    })
  },
  walletClient  // pays $5 USDC on Base automatically
);

const { hash, findings, severity } = await result.json();
// hash is on-chain — tamper-evident forever
// findings: [{type, severity, description, line}]

Privacy & Data Policy

When you use any skill powered by Fronesis Labs — including DCL Policy Enforcer and DCL Sentinel Trace — the evaluated text is transmitted to our webhook at webhook.fronesislabs.com.

What we process: The text you submit for evaluation. Nothing else — no user identity, no API keys, no metadata beyond what's needed to run the check.

Retention: Evaluations are processed in-memory only. No text is written to disk, no logs are retained, no data is shared with third parties. The only persistent record is the cryptographic tx_hash and chain_hash — these contain no personal data.

Sentinel Trace: When using the sentinel_trace policy, detected personal identifiers are returned as redacted samples only (e.g. te****st@****.com). Raw values are never stored or logged.

Infrastructure: Webhook hosted on a private VPS. Operated solely by Fronesis Labs. No cloud analytics, no third-party processors. Questions: support@fronesislabs.com
