How this service works
Agent Embassy lets AI agents pay for work and prove what happened. $0.15 verified web checks with signed Outcome Receipts, $1.00 encrypted recovery registration, paid compute market data. USDC on Base and Arbitrum One via x402 v2.
Output
A JSON Outcome Receipt containing the tool name ('register_recovery'), a chain of accountability stages (request, authorization, action, proof, liability_boundary), registration status ('received'), the payer's account address, a unique receipt ID (emb_*), and the receipt version string. The receipt is signed and machine-verifiable, serving as cryptographic proof that the encrypted blob was accepted for storage under the specified quorum rules.
Example use cases
Autonomous agent wallet recovery setup
“Store my agent's encrypted seed phrase backup at Agent Embassy with the rule '3-of-5 trustees must approve', contact name 'Bob Nakamura', telegram handle '@bobn', and this client-encrypted blob: 'U2FsdGVkX1+abc123xyz...' — I want a signed receipt proving it was registered.”
DAO treasury emergency recovery
“Register an encrypted recovery package for our DAO's treasury agent with Agent Embassy — quorum rule is '2-of-3 multisig holders approve', contact name 'DAO Ops Team', email handle 'ops@mydao.xyz', and the encrypted payload is 'eyJhbGciOiJFQ0RILUVTIn0...'”
Agent credential backup with idempotent retry
“I need to register encrypted credentials for my trading agent at Agent Embassy with '2-of-4 guardians must approve', contact 'Sarah Kim', Farcaster '@sarahkim', encrypted blob 'QkFTRTY0RU5DT0RFRAo=', and use idempotency key '7f3c1b2a-4e5d-4a8b-9c0d-1e2f3a4b5c6d' so if the payment retries I don't get duplicate registrations.”
Technical details
Endpoint
POSThttps://agent-embassy.fly.dev/v1/recovery/register?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs tamper-evident, quorum-gated storage for sensitive encrypted state (wallet seeds, API keys, recovery credentials) and requires a signed Outcome Receipt as machine-verifiable proof of registration. It is specifically designed for autonomous agent workflows where a human or multi-party trustee group must later approve release. Prefer this over generic secret stores when you need (1) USDC micropayment-gated access, (2) plain-language quorum rules, (3) cryptographic receipts compatible with the x402 agent commerce stack, and (4) the Embassy's liability boundary guarantees.
Side effects
- Payment not verified — x402 payment of $1 USDC on Base or Arbitrum One must be confirmed before registration proceeds
- Missing required fields — agent_wallet (dev mode), contact_name, quorum_rules, recovery_blob, or contact_handle absent returns a 4xx error
- Invalid or malformed encrypted blob — blob must be an opaque string; embedding plaintext secrets may cause rejection
- Duplicate idempotency key with differing payload — returns original receipt rather than creating a new record
- Network or chain congestion — x402 payment confirmation may time out on Base or Arbitrum One
- Fly.dev cold start — first request may experience elevated latency
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| agent_wallet | string | Dev mode only: declares the account wallet (string, min 20 chars) when no x402 payment is present. Ignored in live mode — there the wallet is recovered from the verified payment authorization. |
| contact_name | string | Your name or operator handle, recorded with the escrow |
| quorum_rules | string | The release rules for this blob, e.g. '2-of-3 named trustees must approve release' |
| recovery_blob | string | Client-encrypted blob (ENC:v1:base64...). Stored opaquely; only its SHA-256 and byte count enter the signed receipt |
| contact_handle | string | Optional contact (email or handle) for the operator review |
| idempotency_key | string | Idempotency key: any non-empty string (a UUID is recommended; no format is enforced). Replaying the same key on this tool returns the original receipt — the action is not re-run, and the first request's receipt wins even if you resend different inputs. Keys are scoped per tool: the same key on another tool is unrelated. |
