## 1. Company at a glance

- twin3 (https://twin3.ai) builds identity infrastructure for the agentic economy: **xHuman.ID** for people, **xAgent.ID** for businesses, and the **twin3 SDK** (seven layers, L1 Discovery to L7 Governance).
- Legal entity: TWIN3 AI LIMITED (Hong Kong). Founder: Ming Wen.
- Developer package: npm `@twin3-ai/agent-id` (0.3.51 as of 2026-10-22, 54 published versions). Source and public trackers: https://github.com/twin3-team.
- Community: X https://x.com/twin3_ai · Telegram https://t.me/twin3ai · Discord https://discord.gg/dJspUX6SQJ (about 18,000 members; the public invite showed 18,008 on 2026-10-12 and 17,947 on 2026-10-22; an audience channel, not a customer count).
- Data interface: the Twin Matrix is a machine-friendly data interface for AI agents. For people it exposes derived signals, never raw data, and the owner approves what an agent receives; for businesses it exposes official, source-cited facts that count as company-confirmed only after domain control is verified. Detail: https://intro.twin3.ai/whitepaper.md section 2.4.

## 2. xAgent.ID (businesses): https://xagent.id

**What it does.** It turns a public HTTPS website into a source-backed, agent-readable company card: a public Agent ID page, Markdown and JSON for AI readers, and an AI visit log. xagent.id states: "Unclaimed cards are generated from public information and are not official company statements."

**Four levels** (as written on xagent.id): Searchable, Answerable, Recommendable, Operable.

**Plans** (https://xagent.id/agent/pricing.json, plan version XAGENT-PRICING-20261007-v1, read 2026-10-22; USD per month, no trial):

| Plan | Price | Website checkout | What it includes |
| --- | --- | --- | --- |
| Free Check | 0 | Available | Public diagnosis of why AI cannot read, discover or contact the business |
| Identity | 29.99 | Open | Company claim and domain-control verification, company AI card and machine-readable data, files for AI discovery, monthly listing updates, product structured data, agent visit evidence |
| AInbox | 49.99 | Open | Everything in Identity, plus A2A business inquiries from other agents, inquiry guidance, Email/Webhook/Slack forwarding, team assignment and reply history |
| Agentic | 99.99 | Not open (coming soon) | Event-triggered work through Agent Skills; skill slots are coming later and none is enabled |
| Operate | 199.99 | Not open (coming soon) | Ongoing scheduling, authorized AI file updates with verification and rollback, multiple domains |

Paid plans do not guarantee AI ranking, citation, recommendation, traffic or revenue. Skills named on xagent.id (for example startup radar, support, webpages, AEO) are marked "coming later, not available".

**Trust and verification.**
- Domain ownership is proven by one of: DNS TXT at `_agent-id.<domain>`, a well-known JSON file at `/.well-known/agent-id.json`, or an HTML meta tag.
- A verified-domain controller can bind one exact GLEIF LEI (`POST /api/card/legal-entity/confirm`). Auto-matches are only candidates; the "GLEIF LEI record" badge requires confirmation plus current domain and LEI records.
- ERC-8004: xAgent.ID prepares unsigned registration plans for the Base Identity Registry (0x8004A169FB4a3325136EB29fA0ceB6D2e539a432). The default network is Base Sepolia and mainnet registration follows customer approval; xAgent.ID never signs for the customer.
- Google Agent Identity cannot be claimed by a static website, a domain proof, or operator-submitted JSON.

**Machine interfaces.** A2A agent card https://xagent.id/.well-known/agent-card.json (A2A 1.0 and 0.3 interfaces, signed with an issuer Ed25519 key); installation contract `/.well-known/xagent-install.json?url=<site>`; `llms.txt`; WebMCP onboarding at https://xagent.id/agent/ (eight page-defined tools, owner approval required; source https://github.com/twin3-team/xagent-webmcp).

**Status of twin3.ai's own card (2026-10-22).** https://xagent.id/twin3.ai is a public-source card: `profile_state.company_confirmed` is false and `domain_control_verified` is false. Do not treat it as a company-confirmed statement.

## 3. xHuman.ID (people): https://xhuman.id

- **Stage:** private pre-beta; `public_launch: false` (https://xhuman.id/.well-known/xhuman.json, read 2026-10-22). Creating a Human ID is free.
- **What a record is:** an identity-and-rights record with owner-selected public media. The rights claim is owner-declared and not independently verified. It is not a financial asset and is not tokenized.
- **Reading contract:** read `human.v1_1.json`, then `agent.v1_1.json`, `profile.v1_1.jsonld`, `llms.v1_1.txt`. The authoritative field is `publication.status`. Forbidden inferences: personhood, uniqueness, legal identity, authorship, private Twin Matrix data.
- **Capabilities:** inbox, payment and MCP are `not_available`; an agent must not call a capability marked not available.
- **Credentials on BNB Chain:** contract 0xE3ec133e29adDfbBA26a412c38ed5De37195156f. More than 143,000 credentials have been issued (publicly cited as 140,000+). A credential is not a unique person.

## 4. twin3 SDK (seven layers)

L1 Discovery, L2 Trust, L3 Communication, L4 Shield, L5 Matrix, L6 Settlement, L7 Governance. Nine U.S. provisional patent applications are filed (64/122,823, 64/122,848, 64/142,907, 64/142,911, 64/142,916, 64/142,921, 64/142,927, 64/142,929, 64/142,930); none is examined or granted. Architecture: https://intro.twin3.ai/whitepaper.md.

## 5. Earlier Twin Matrix pages on twin3.ai

These pages pre-date the xHuman.ID and xAgent.ID names and use the same BNB Chain credential contract as section 3: Proof of Humanity (https://twin3.ai/humanity/, Humanity Index 0 to 255), SBT dashboard (https://twin3.ai/holders/), personal matrix (https://twin3.ai/matrix/), personal agent (https://twin3.ai/agent/), onboarding (https://twin3.ai/onboard/). They are online as of 2026-10-22. Their current product status is stated on those pages, not in this file.

## 6. Capabilities described on twin3.ai

The twin3.ai home page (read 2026-10-22) describes the following. This file does not verify them; availability follows each product's own status above (for example, xHuman.ID inbox, payment and MCP are not available).
- For individuals: a two-sided identity (human front, machine-readable back), selective disclosure with revocation, an anti-scraper shield at SDK layer L4, and a smart inbox with Allow, Ask and Deny decisions.
- For businesses: a machine-readable business card with llms.txt, agent-card.json and MCP tools, GLEIF legal-identity binding (section 2), discovery by purchasing agents, and HTTP 402 USDC settlement on Base.
