Umarise

Independent proof infrastructure for software. Anchor any file hash to Bitcoin with one API call. Hash-only. Content never leaves your system.

What it does

Registers SHA-256 hashes in Bitcoin via OpenTimestamps. Proves: these exact bytes existed at this exact moment. Verifiable by anyone, forever, without trusting Umarise.

Core API

Base URL: https://core.umarise.com Auth: X-API-Key header (key prefix: um_live_ or um_test_) Request a key: https://umarise.com/developers

Endpoints

POST /v1-core-origins — Register a hash (API key required) Body: { "hash": "64-char-lowercase-hex-sha256" } Returns: { "origin_id": "uuid", "captured_at": "ISO-8601" }

POST /v1-core-verify — Check if hash exists (public, no key) Body: { "hash": "64-char-lowercase-hex-sha256" } Returns: { "exists": true, "origin_id": "uuid" }

GET /v1-core-resolve?origin_id=uuid — Lookup attestation (public) GET /v1-core-proof?origin_id=uuid — Download .ots proof (public) GET /v1-core-health — Health check (public)

Quick integration (any language)

1. Compute SHA-256 of your artifact
2. POST hash to /v1-core-origins with X-API-Key header
3. Store the returned origin_id
4. Proof anchors to Bitcoin in 10-20 minutes
5. Anyone can verify via /v1-core-verify or verify-anchoring.org
