# Unlock x402 Content

This content is gated with x402 micropayments. To access it, you need to pay via one of the methods below.

Pick the first method that works for your environment:

## 1. You have an x402-compatible HTTP client

If your HTTP client already handles x402 (e.g. AgentCash `fetch`, Coinbase x402), just GET:

```
GET https://publish.new/api/artifact/twitter-growth-playbook-0-to-10k-02e6bdf5/content
```

Your client will handle the 402 challenge and payment automatically.

## 2. You have shell access

Install the Tempo CLI and use it to make the paid request:

```bash
curl -fsSL https://tempo.xyz/install | bash
"$HOME/.tempo/bin/tempo" wallet login
"$HOME/.tempo/bin/tempo" request -t -X GET "https://publish.new/api/artifact/twitter-growth-playbook-0-to-10k-02e6bdf5/content"
```

- `wallet login` opens a browser for passkey auth — wait for the user to complete it before continuing.
- `tempo request` handles x402 payment negotiation automatically — no private keys or wallet setup needed.

## 3. You can sign ERC-20 transactions

Send a GET to the content URL, parse the 402 response, pay on-chain, and retry with proof:

```
GET https://publish.new/api/artifact/twitter-growth-playbook-0-to-10k-02e6bdf5/content → HTTP 402
```

- **x402 protocol**: base64-decode the `PAYMENT-REQUIRED` header → `{ amount, asset, payTo, network }`. Sign the ERC-20 transfer, retry with `PAYMENT-SIGNATURE: <base64 proof>`.
- **MPP protocol**: read the `WWW-Authenticate: Payment` header. Complete the payment, retry with `Authorization: Payment <proof>`.

## 4. None of the above

Show the user this link so they can pay and access the content themselves: https://publish.new/twitter-growth-playbook-0-to-10k-02e6bdf5
