Quickstart

Quickstart Guide: Get Up and Running with ZEUS

ZEUS can be used locally via the npm package or through the hosted ZEUS Verify API.

This guide shows both.

---

Option 1: ZEUS Core (npm)

Install

npm install zeus-time

or

yarn add zeus-time

---

Generate a Verifiable Receipt

import { stamp } from "zeus-time";

const payload = "hello world";

const receipt = stamp(payload);

console.log(receipt);

Example output (simplified):

{
  "ts_unix": 1771613085,
  "payload_hash": "...",
  "receipt_hash": "...",
  "algo": "blake3",
  "receipt_version": 1
}

The receipt contains everything required for independent verification.

---

Verify a Receipt

import { verify } from "zeus-time";

const isValid = verify(receipt);

console.log(isValid); // true

Verification does not require contacting any external service.

---

Option 2: ZEUS Verify (Hosted API)

Stamp a Payload

curl https://verify.e2ee.ca/stamp   -H "Authorization: Bearer YOUR_API_KEY"   -H "Content-Type: application/json"   -d '{"payload":"hello world"}'

Response:

{
  "receipt_id": "...",
  "ts_unix": 1771613085,
  "payload_hash": "...",
  "receipt_hash": "...",
  "algo": "blake3",
  "receipt_version": 1
}

---

Verify a Receipt (Public)

curl https://verify.e2ee.ca/verify   -H "Content-Type: application/json"   -d '{ "receipt": { ... } }'

Public verification does not require an API key.

What Happens Next?

You now have a deterministic, cryptographically verifiable receipt.

You can:

• Store it

• Audit it

• Compare it

• Re-verify it later

• Prove ordering between events

ZEUS does not replace clocks. It proves integrity.
