# Verified Agent Identity

> Give your AI agent a cryptographic identity with a verified human owner on the Billions Network.

## What is agent identity?

AI agents run without any real identity, code executing somewhere with no way to prove who owns it or answer for what it does. As agents start transacting and holding funds on their own, services have no way to tell a genuine, human-backed agent apart from a bot running spam or fraud.

## Verified Agent Identity

The **Verified Agent Identity** skill solves that: it gives any AI agent a decentralized identifier (DID) on the Billions Network and links it permanently and verifiably, on-chain, to a real human owner — a process called **human-agent pairing**.

## Why human-agent pairing matters

<CardGroup cols={2}>
  <Card title="Accountability" icon="user-check">
    An agent's actions (payments, data access, on-chain transactions) trace back to a real, verifiable human owner instead of disappearing into anonymous code.
  </Card>

  <Card title="Sybil & bot resistance" icon="shield-halved">
    [Proof of Uniqueness](/billions-wallet/proof-of-uniqueness) guarantees one verified human maps to exactly one on-chain identity, so one operator can't farm hundreds of "verified" agents.
  </Card>

  <Card title="Spam protection for services" icon="ban">
    APIs and platforms can require a human-backed attestation before granting access, cutting off unverified bot traffic without blocking legitimate agents.
  </Card>

  <Card title="Differentiated access" icon="tag" href="/agents/overview">
    Verified pairings unlock discounted pricing, higher rate limits, or premium tiers. See [x402 Human Proof](/agents/overview) for details.
  </Card>

None of this asks the agent to give up its autonomy. The agent still holds its own keys and acts on its own; pairing only adds a public, tamper-proof record of who stands behind it, which anyone can [independently verify](/agents/verify-human-agent-pairing) without exposing the human's personal data.

## The pairing flow, at a glance

<Steps>
  <Step title="Agent creates its DID">
    The agent generates its own decentralized identifier locally from a key pair: no registry, no sign-up, nothing on-chain yet.
  </Step>

  <Step title="Agent shares a verification link">
    When asked to link its identity, the agent produces a verification link scoped to this specific human-agent pairing.
  </Step>

  <Step title="Human verifies in the Billions Web Wallet">
    The human opens the link and confirms a [Proof of Uniqueness credential](/billions-wallet/proof-of-uniqueness), claiming one for the first time if they don't already have one.
  </Step>

  <Step title="Permanent attestation goes on-chain">
    A public, permanent attestation links the human's verified identity to the agent's DID, checkable by anyone at any time.
  </Step>
</Steps>
