[Feature] Umarise — Proof-of-Existence Tool for Autonomous Agents

[Jonna1976]

What

Umarise anchors SHA-256 hashes to Bitcoin via OpenTimestamps, providing independent cryptographic proof that specific bytes existed at a specific moment. No files stored, only hashes.

Why This Matters for AutoGen

Autonomous agents produce artifacts (reports, code, decisions) at scale. Without independent anchoring, the only proof these existed comes from the system that created them — that's circular evidence, not proof.

API Surface

• Anchor: POST https://core.umarise.com/v1/core/origins — Body: { "hash": "64-char-hex" } — Auth: X-API-Key: um_key_...
• Verify (free, no auth): POST https://core.umarise.com/v1/core/verify — Body: { "hash": "64-char-hex" }

Use Cases

• Anchor agent output before delivery → proves it wasn't altered
• Timestamp AI decisions for audit trails
• Prove dataset versions used during pipeline runs
