# Wallet Quickstart

> Get a Lightning wallet in 60 seconds. No bank. No KYC. Works in 193 countries.

You need a Lightning wallet to pay L402 APIs. Two options — both free, both work globally.

***

## Option A — Blink (recommended)

<Steps>
  <Step title="Create account">
    Go to [blink.sv](https://blink.sv) and sign up with a phone number or email.
  </Step>

  <Step title="Copy your Lightning Address">
    In the app: **Settings → Lightning Address**. It looks like `yourname@blink.sv`.
  </Step>

  <Step title="Get your API key">
    Go to [dashboard.blink.sv](https://dashboard.blink.sv) → **API Keys** → create a key.
  </Step>

  <Step title="Use in l402-kit">
    ```typescript theme={null}
    import { ManagedProvider } from "l402-kit";

    const provider = ManagedProvider.fromAddress("yourname@blink.sv");
    ```

    Or with the Agent SDK:

    ```typescript theme={null}
    import { buildWallet } from "l402-kit/agent";

    const wallet = buildWallet({ BLINK_API_KEY: "your-key" });
    ```
  </Step>
</Steps>

***

## Option B — Alby

<Steps>
  <Step title="Create account">
    Go to [getalby.com](https://getalby.com) and sign up.
  </Step>

  <Step title="Get your OAuth token">
    Go to [getalby.com/api-tokens](https://getalby.com/api-tokens) and create a token with `payments:send` scope.
  </Step>

  <Step title="Use in l402-kit">
    ```typescript theme={null}
    import { buildWallet } from "l402-kit/agent";

    const wallet = buildWallet({ ALBY_TOKEN: "your-token" });
    ```
  </Step>
</Steps>

***

## Zero-config via environment variables

l402-kit auto-detects your wallet from env vars. No code changes needed:

```bash theme={null}
# Blink
export BLINK_API_KEY="your-key"

# Alby
export ALBY_TOKEN="your-token"
```

```typescript theme={null}
import { buildWallet } from "l402-kit/agent";

const wallet = buildWallet(process.env); // auto-detects Blink or Alby
```

***

## Fund your wallet

Both wallets give you a Lightning address to receive sats. To test:

1. Go to [coinfos.net](https://coinfos.net) or any faucet
2. Send 1000 sats to your Lightning address
3. Run `npm install l402-kit && node -e "require('l402-kit/agent').healthCheck()"`
