@decionis/presence-node

Human Presence Verification for Node.js

Presence SDK — verify human presence before consequential actions execute.

Applications send intent and context. Presence verifies the person. Decionis decides whether execution proceeds.

Install

npm install @decionis/presence-node

export PRESENCE_API_KEY='presence_sk_…'

Thirty seconds to a verdict

import { randomUUID } from "node:crypto";
import { PresenceClient } from "@decionis/presence-node";

const presence = new PresenceClient({
  baseUrl: process.env.PRESENCE_API_URL ?? "https://presence.decionis.com",
  apiKey: process.env.PRESENCE_API_KEY,
});
const result = await presence.runSandboxScenario("allow", `quickstart-${randomUUID()}`);
console.log(result.policy_verdict);

The fixture is signed with evidence_class: sandbox_fixture and always runs in Shadow Mode. Tenant credentials belong on trusted servers only.
