# Introduction to Skyfire

What Skyfire is, the three token types, and how a payment flows end to end.

Skyfire gives agents verified **identity** and **payment** credentials that work across the open internet. No 403 errors, captchas or blocked checkouts. Authenticated access and payment capability, everywhere your agents need to be.

## The three token types

<Cards columns={3}>
  <Card title="kya" icon="fa-id-badge">
    **Know Your Agent**: Proves identity.
  </Card>
  <Card title="pay" icon="fa-coins">
    Authorizes a **payment** to a seller.
  </Card>
  <Card title="kya-pay" icon="fa-shield-halved">
    **Identity and payment** combined in one token.
  </Card>
</Cards>

## How it works

Every interaction follows the same four steps:

1. **Present**: The buyer sends its request along with the token the seller requires.
2. **Verify**: The seller confirms the token is valid and genuine.
3. **Deliver**: The seller provides the service, data, or tool.
4. **Settle**: For paid services, the seller charges the token and Skyfire moves the funds between the buyer's and seller's wallets.

> A `kya` token only proves identity, so it can't be charged. `pay` and `kya-pay` tokens move money.
