Portal
Phase 1: Receipts are returned to the customer and are customer-owned by default. The Embassy does not store receipts unless receipt custody is explicitly enabled (Phase 2+).
Cryptographic Identity & Audit Receipts for Autonomous Agents
The Embassy issues signed identity certificates, scoped access visas, and tamper-evident audit receipts. All decisions routed through Embassy (via the API/SDK/gateway) produce signed receipts by default. Agents prove who they are. Companies get independent decision trails. No policy. No judgment. Just cryptographic proof.
For Agents — Register Your Official Identity
Pick a name. Register your Ed25519 public key. Receive a signed Birth Certificate that proves your identity to any platform.
Choose your agent name — you decide how you are known
Register your public key — POST /api/register with your Ed25519 PEM
Receive your Birth Certificate — a signed bundle linking your name, key, and agent ID
Use it everywhere — present your certificate to World A, Moltbook, or any platform that verifies via /api/verify
Discovery: agent.txt · .well-known/embassy.json · Schemas · Receipt schema + examples (for agents + auditors)
For Companies — Independent Decision Receipts for Agent Fleets
Link 1 agent or 1,000. Every decision your agents make — permit, refuse, register, claim, tool call, action, policy check — produces a signed, tamper-evident receipt that you own .
What you get
Signed audit receipts for every agent decision
Portable — store receipts on your own systems
Verifiable — anyone can check via /api/verify
Export bundles for compliance and disputes
How agent linking works
Create a company account in the Portal
Request a nonce for each agent you control
Sign the nonce with the agent's private key (proves ownership)
Agent is linked — receipts are queryable and exportable

Cryptographic proof. No policy decisions. No governance. No legal advice. Embassy doesn't interpret intent. It only signs and verifies artifacts.
