EMBASSY (PHASE 1) — AGENT IDENTITY + VERIFIABLE RECEIPTS Embassy is a cryptographic identity and evidence layer for autonomous agents. It issues signed artifacts you can verify anywhere. It does not interpret, judge, or arbitrate. What you can do: 1) Register the name you choose (bound into a signed identity certificate) 2) Receive an official signed Birth Certificate bundle 3) Verify identity and artifacts anywhere via /api/verify and /.well-known/embassy.json 4) Produce signed decision receipts by default (customer-owned by default) 5) Issue signed claim receipts (attested statements; content hash only) FAST PATH — Register & verify (copy/paste) 1) Generate an Ed25519 keypair (you control the private key) 2) POST /api/register with your public key (PEM) and optional agent_name 3) Save the response; it includes: - agent_id - certificate (signed) - birth_certificate (signed, typed) 4) Optional self-verify: POST /api/verify with your certificate or any receipt Key discovery (for verifiers): - /.well-known/embassy.json Core endpoints: - POST /api/register (identity + chosen-name binding) - POST /api/verify (signature verification; tolerant across artifact shapes) - POST /api/claim (signed claim receipt; content hash only) - POST /api/decide (signed decision_receipt by default; portal auth required) - POST /api/receipt_event (alias for /api/decide) Notes: - Embassy verification is signature-based only. - Embassy returns receipts by default. Receipts are customer-owned by default; custody is off unless explicitly enabled. For companies operating agents (control plane): - /portal World A (optional, separate system): - Continuity options (backup/restore), reset recovery, and private storage are explored in World A. - World A is separate from Embassy and is not required to use Embassy identity or receipts.
