Digital identity for AI agents.

Q: What exactly is an AliasKit identity?

A complete digital persona for an AI agent — a real email inbox, optional phone number, optional virtual card, and metadata. You create and delete them through the API or SDK.

Q: What can I do on the free tier?

Up to 5 persistent identities, each with a real @aliaskit.com email inbox, 5 virtual cards, 1 phone number with inbound and outbound SMS, OTP extraction, and 30 API requests per minute.

Q: What does Pro unlock?

Up to 50 identities, 50 virtual cards, 20 phone numbers with SMS, TOTP, custom email domains, and 300 requests per minute. $29/month.

Q: What integrations are available?

A TypeScript SDK that wraps every API endpoint, plus a REST API that works with anything. MCP server and agent framework plugins are coming soon.

Q: Is this a disposable email service?

No. AliasKit provides persistent digital identities for AI agents. Inboxes are for long-running agent workflows you control, not anonymous use. All usage must comply with our terms.

Q: Can I use my own domain for email?

Yes, on Pro. Add your domain, configure the DNS records we provide (SPF, DKIM, DMARC), and your identities can send from your-agent@yourdomain.com.

Give any AI agent a persistent digital identity with a real email inbox, phone number, virtual card, and TOTP codes. One API call. Your agent operates on the internet like a human remote worker.

Agent Identities, All In One Place.

Email, phone, cards, and auth tokens on every plan. W3C DID documents, Verifiable Credentials, ERC-8004 on-chain linking, and reputation scoring — one API.

Every identity gets a real @aliaskit.com inbox. Receive verification emails, send outbound, search and thread conversations.

email-identities.ts

const identity = await ak.identities.create()
// → { email: "agent-47@aliaskit.com" }
 
const email = await ak.emails.waitForCode(identity.id)
// → { from, subject, body_text }
// parse the verification code from email.body_text
 
const emails = await ak.emails.list(identity.id)

→Realtime WebSocket delivery
→Email threading and search

Your agents can make purchases

ONLY ON ALIASKIT

Zero-knowledge card storage. AliasKit never sees your plaintext card details. Encryption and decryption happen on your device. Your agent can complete checkout flows through the API with declared spending budgets.

Zero-knowledge encryption. We never see your card details. When using agents, we recommend a virtual card from your bank (Revolut, Monzo, Wise) with a spending limit. Keeps your main account separate.

Create an identity

One API call provisions a real email inbox, optional phone number, virtual card, and W3C DID document.

const id = await ak.identities.create()

Interact with the world

Your agent signs up for services, captures OTPs, makes payments, and proves identity to other agents.

await ak.emails.waitForCode(id.id)

Three ways teams use AliasKit

Whether you're automating, transacting, or securing, the same API handles it all.

Give agents real-world identity

Your AI agent signs up on any website using its own email, phone, and virtual payment card. AliasKit captures verification codes automatically.

Run autonomous purchases and bookings

Provision a per-identity virtual debit card with isolated balance. Your agent pays for SaaS, books travel, or runs ad spend within the limits you set.

Prove identity with open standards

Built for production

Read how identities and keys relate in Concepts and the full API Reference.

W3C Standards

DID:web documents, Verifiable Credentials (VC-JWT), and ERC-8004 on-chain linking. Built on open standards, not proprietary lock-in.

Organization isolation

Every identity, message, and card is isolated per organization. Scoped API keys with granular permissions, hashed at rest.

Webhooks & events

HMAC-SHA256 signed webhooks with delivery tracking. Realtime event subscriptions for email, SMS, card, and reputation changes.

Cryptographic verification

RS256 + ES256 agent tokens verified via public JWKS endpoint. Issue W3C Verifiable Credentials for portable reputation proofs.

Built on Web3 & W3C Standards

Your agents deserve identity that works everywhere — not just inside your stack. Open standards mean any service can verify your agent without a single API call back to us.

Decentralized Identifiers

Your agents get a globally resolvable identity that any service can verify without calling your API.

→W3C DID:web document per agent
→RS256 + ES256 key material
→No vendor lock-in

{
  "@context": "https://w3.org/ns/did/v1",
  "id": "did:web:aliaskit.com:…",
  "verificationMethod": [
    { "alg": "RS256" },
    { "alg": "ES256" }
  ]
}

Verifiable Credentials

Let your agents prove their reputation to any third party with a signed credential they can verify offline.

→W3C VC Data Model 1.0
→Score, tier, capabilities embedded
→Offline verification via JWKS

{
  "vc": {
    "type": [
      "VerifiableCredential",

    ],
    "credentialSubject": {
      "score": 0.87,
      "tier": "platinum"
    }
  }
}

ERC-8004 On-Chain Identity

Anchor your agent's identity on-chain so smart contracts and DeFi protocols can verify trust trustlessly.

→Ethereum, Optimism, Sepolia
→EIP-191 signature verification
→On-chain reputation metadata

{
  "tokenId": "42",
  "chainId": 1,
  "ownerAddress": "0xAb58…",
  "signature": "0x3f2a…"
}

Trust Scoring

Every agent earns a reputation score over time. Other services get instant allow/review/deny decisions via API.

→Bronze to Platinum tiers
→Real-time trust evaluation
→Feeds into portable VC proofs

{
  "trusted": true,
  "score": 0.87,
  "tier": "platinum",
  "decision": "allow"
}

Agents earn trust over time

Every identity builds a reputation score based on activity — bronze to platinum tiers with allow/review/deny trust decisions. Issue W3C Verifiable Credentials to prove reputation portably. Resolve agent identity via public DID documents.

Common questions

Virtual cards included on all plans. TOTP is a Developer+ feature. Email and 1 phone number included on Free.

What exactly is an AliasKit identity?+

A complete digital persona for an AI agent: a real email inbox, optional phone number, optional virtual card, and metadata. You create and delete them through the API or SDK.

What can I do on the free tier?+

Up to 5 persistent identities, each with a real @aliaskit.com email inbox, 5 virtual cards, 1 phone number with inbound and outbound SMS, OTP extraction, and 30 API requests per minute.

What does Pro unlock?+

Up to 50 identities, 50 virtual cards, 20 phone numbers with SMS, TOTP, custom email domains, and 300 requests per minute. $29/month.

How do virtual cards work?+

AliasKit uses zero-knowledge encryption. Your card details are encrypted and decrypted on your device, so we never see your plaintext card data. We recommend using a virtual card from your bank (Revolut, Monzo, Wise, etc.) with a spending limit as your primary safety net. Your card encryption key is generated once and cannot be recovered by AliasKit.

What integrations are available?+

A TypeScript SDK that wraps every API endpoint, plus a REST API that works with anything. MCP server and agent framework plugins are coming soon.

Is this a disposable email service?+

No. AliasKit provides persistent digital identities for AI agents. Inboxes are for long-running agent workflows you control, not anonymous use. All usage must comply with our terms.

Can I use my own domain for email?+

Yes, on Pro. Configure your domain in the dashboard, set up the DNS records we provide (SPF, DKIM, DMARC), and your identities will use your custom domain.
