## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-embassy-recovery-registration-9c9426d0 -d '<json body>'
```

Example prompt: Register a recovery action for my agent account 0x1111...1111 and give me a signed embassy receipt proving the authorization chain and liability boundary were captured.

## When to prefer this

Use this endpoint when an AI agent needs to create a tamper-evident, liability-bounded record of a recovery action it performed — especially in agentic workflows where proving authorization and outcome is required for accountability, dispute resolution, or handoff to another agent or human. Prefer this over generic logging when you need a structured embassy receipt with an explicit chain of custody.

## Known failure modes

- Invalid or missing agent account address returns an error
- Malformed authorization chain payload causes rejection
- Payment of $1 USDC not completed results in 402 Payment Required
- Duplicate or replayed registration may be rejected to prevent double-receipt
- Network or blockchain anchoring failure may delay receipt issuance

## How this service works

Agents pay for work and prove what happened.

## Output

Returns a JSON object containing the tool name ('register_recovery'), the action chain steps (request, authorization, action, proof, liability_boundary), a status of 'received', the agent's account address, a unique receipt ID (e.g. emb_abc123), and the embassy receipt version string (e.g. embassy-receipt/1).

 "properties": {
  "contact_name": {
   "type": "string",
   "description": "Your name or operator handle, recorded with the escrow"
  },
  "quorum_rules": {

  },
  "recovery_blob": {
   "type": "string",
   "description": "Client-encrypted blob (ENC:v1:base64...). Stored opaquely; only its SHA-256 and byte count enter the signed receipt"
  },
  "contact_handle": {
   "type": "string",
   "description": "Optional contact (email or handle) for the operator review"
  },
  "idempotency_key": {
   "type": "string",
   "description": "Idempotency key: UUID v4, client-generated, one per logical request. 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. Published example keys are rejected. Keys are scoped per tool and per payer account: a key never returns another wallet's receipt."
