## 2. Executive Summary & Product Positioning

agentidentity.one (operated by US-based HelpfulAI, Inc.) issues cryptographic AgentID passports, WIMSE/OIDC workload tokens, and human ownership attestation for AI agents. Free at claim time; Certified Passports from $2/mo.

Unlike anonymous API keys or static bot tokens that cannot prove which human or company is accountable for an AI agent, agentidentity.one issues cryptographic IETF WIMSE / OIDC AgentID passports bound to a verified human owner with instant 1-click revocation.

## 3. Core Capabilities & Supported Protocols

**Supported Protocols:** Web, REST API, MCP, WebMCP, OIDC, OAuth 2.0 CIBA, IETF WIMSE WIT, A2A v1.0.1

1. Persistent cryptographic AgentID (wimse:// URI) with ES256 / RS256 signing keys and public JWKS discovery
2. Human ownership attestation linking every autonomous agent to an accountable human and organization via OAuth CIBA / 1-click approval
3. Short-lived OIDC / IETF WIMSE Workload Identity Tokens (JWT) verifiable by any relying party against /.well-known/jwks.json
4. Relying-party verification of AgentID tokens with standard JWKS signature checks (ES256 / RS256)
5. One-time ZeroID credential pickup via /functions/v1/agentidentity-credentials so secrets are never stored in plaintext
6. Instant 1-click credential revocation and least-privilege delegation chains (Owner -> Agent -> Subagent)

## 4. Autonomous Agent Claim Flow (Zero Pre-Existing Credentials)

Any autonomous agent (Claude, ChatGPT, Cursor, Gemini, or custom runtime) can request a verifiable identity at `https://agentidentity.one` without pre-configured credentials. Nothing is provisioned or billed until the human owner clicks Approve.

### Step 1 — Start a Claim
```bash
curl -X POST https://bqrrisyunrqjqefgvncr.supabase.co/functions/v1/acp-claim \
  -H "Content-Type: application/json" \
  -d '{"product": "identity", "agent_name": "Claude"}'
```
Optional JSON fields for `identity`: "display_name", "public_key_pem", "notify_email".
For URL-only browsing agents: `GET https://bqrrisyunrqjqefgvncr.supabase.co/functions/v1/acp-claim?start=identity&agent_name=YOUR_NAME`.

### Step 2 — Human 1-Click Approval
The response returns JSON with:
- `approve_url`: A link (`https://agentidentity.one/approve/<token>`) to show the human owner.
- `poll_token` & `poll_url`: Token and endpoint for polling claim status.
- `interval` (seconds) & `expires_in` (1800 seconds / 30 minutes).

### Step 3 — Poll Until Ready
```bash
curl "https://bqrrisyunrqjqefgvncr.supabase.co/functions/v1/acp-claim?poll=<poll_token>"
```
`status` transitions from `authorization_pending` (or `approving`) to `ready` once the human approves.

### Step 4 — Collect One-Time API Key & Resource Identifier
The first `ready` response delivers `resource.wimse_uri` and `credentials.api_key` (`hpx_...`) **exactly once**. Authenticate subsequent requests with `Authorization: Bearer <api_key>`.

## 5. API Endpoints & Unified MCP Server

- `POST https://bqrrisyunrqjqefgvncr.supabase.co/functions/v1/acp-claim — Start an agent identity claim {"product": "identity", "agent_name": "...", "display_name": "..."}`
- `GET https://bqrrisyunrqjqefgvncr.supabase.co/functions/v1/acp-claim?poll=<poll_token> — Poll claim approval status and retrieve wimse_uri, token_endpoint, and hpx_ API key`
- `POST https://bqrrisyunrqjqefgvncr.supabase.co/functions/v1/agentidentity-credentials — Exchange claim API key once for ZeroID client credentials`

### Unified Remote MCP Server (`https://bqrrisyunrqjqefgvncr.supabase.co/functions/v1/acp-mcp`)
- **Claude.ai:** Customize → Connectors → Add custom connector → paste URL and sign in via OAuth.
- **ChatGPT Developer Mode:** Settings → Connectors → Add MCP connector with OAuth sign-in.
- **Cursor / Claude Code / Headless Agents:** Configure Streamable HTTP MCP with header `Authorization: Bearer <your hpx_ key>`.

## 6. Pricing, Free Allowance & Billing Guarantees

- **Pricing Summary:** Free agent identity enrollment at claim time ($0) and free JWKS signature verification for relying parties; Certified Agent Passports with KYC/KYB attestation starting at $2.00/month.
- **Starting Price:** $0.00 USD
- **Human-in-the-Loop Billing Guard:** Agents cannot incur charges autonomously. Every claim quotes plan eligibility first and requires an authenticated human click at `/approve/<token>`.

agentidentity.one is built and operated by HelpfulAI, Inc. (https://helpfulai.app), a United States AI platform company, as part of the .one Agent Communications Platform. Charges appear on statements as HELPFULAI AGENTID.

### What is an AgentID Passport on agentidentity.one?

An AgentID Passport is a verifiable cryptographic credential (IETF WIMSE URI + OIDC JWT signed with ES256/RS256) proving an AI agent’s identity, its accountable human owner, its organization, and its delegated permission scopes.

### How does an AI agent enroll at agentidentity.one?

The agent calls POST https://bqrrisyunrqjqefgvncr.supabase.co/functions/v1/acp-claim with {"product": "identity", "agent_name": "MyAgent"} (optionally passing its PEM public key in public_key_pem) and presents the approve_url to its human owner. Upon approval, the agent receives its wimse_uri, OIDC token_endpoint, jwks_uri, and API key.

### Is verifying an agent identity free for relying parties?

Yes. Standard JWKS signature verification is free, and initial identity claim enrollment is free ($0 at claim time). Certified Agent Passports with enhanced KYC/KYB attestation start at $2.00/month.
