ZEUS Verify API Reference

Sandbox time!

ZEUS Verify is a minimal, deterministic receipt issuance API.

It provides cryptographic temporal integrity over submitted payloads.

Base URL:

https://verify.e2ee.ca

All endpoints return structured JSON.

---

Authentication

Authenticated endpoints require a Bearer token.

Header format:

Authorization: Bearer zv_live_your_key_here

Keys are validated server-side and rate limited by tier.

Creates a deterministic ZEUS receipt from payload input.

Determinism guarantee:

Identical payload + identical timestamp input produces identical canonical structure.

Verifies integrity of a receipt.

No authentication required.

Verification checks:

• Canonical structure

• Hash recomputation

• Structural consistency

It does not validate civil time correctness.

ZEUS Verify is infrastructure, not analytics.

Design Principles

• Deterministic structure

• Explicit canonicalization

• Algorithm labeling

• Versioned receipts

• Minimal attack surface

ZEUS Verify does not sell time.

It sells defensible temporal integrity.
