<p>Primer Pay lets you put any post or page behind a micropayment wall using the x402 protocol. Visitors with the Primer Pay browser extension pay seamlessly and see your content instantly. No user accounts, no subscriptions, no payment forms.</p>
<p><strong>How it works:</strong></p>
<ol>
<li>You enter your wallet address in Settings > Primer Pay.</li>
<li>You check “Enable x402 Paywall” on any post and set a price (e.g., $0.01 USDC).</li>
<li>Visitors with the Primer Pay Chrome extension pay automatically and see your content.</li>
<li>Visitors without the extension see a teaser and a prompt to install Primer Pay.</li>
<li>Payments settle on Base (Ethereum L2) via USDC — low fees, instant finality.</li>
</ol>
<p><strong>Features:</strong></p>
<ul>
<li>Gutenberg Content Gate block — visual divider between free teaser and paid content with inline settings</li>
<li>Classic editor support — <code>[primer_pay_x402]</code> shortcode plus sidebar meta box</li>
<li>Per-post price override (defaults to your site-wide price)</li>
<li>Per-post wallet override — route payments to a different wallet per post (multi-author support)</li>
<li>Multi-network: accept payments on Base, SKALE Base, or both — with configurable priority</li>
<li>Theme-matching paywall banner — inherits your site’s fonts, colors, and border radius</li>
<li>Configurable access duration: 30 minutes to “never expires”</li>
<li><code>.well-known/x402</code> discovery endpoint — JSON index for AI agents and crawlers to find purchasable content</li>
<li>Works with any theme that renders the_content() normally</li>
<li>No user accounts or login required</li>
<li>Non-custodial — payments go directly to your wallet</li>
</ul>
<p><strong>Requirements:</strong></p>
<ul>
<li>A wallet address on Base or SKALE Base (e.g., from MetaMask, Coinbase Wallet, or Primer Pay itself — same address works on all supported networks)</li>
<li>HTTPS recommended (cookies are marked Secure on HTTPS; HTTP still works for local dev)</li>
</ul>
<h3>External services</h3>
<p>This plugin relies on the Primer x402 facilitator service to verify and settle payments. When a visitor attempts to pay for content, the plugin sends the signed payment authorization to the facilitator, which validates the signature and executes the on-chain USDC transfer on the Base network.</p>
<ul>
<li>Service: Primer x402 Facilitator</li>
<li>Endpoint: https://x402.primer.systems/settle</li>
<li>When: Whenever a visitor submits a valid X-PAYMENT header to the plugin’s unlock endpoint</li>
<li>Data sent: The base64-encoded signed payment authorization (EIP-712 typed data) from the visitor, plus the payment requirements (amount, asset address, recipient wallet address, network). No personally identifiable information about the visitor is sent — the only identifier is the wallet address they signed with.</li>
<li>Terms of service: https://primer.systems</li>
<li>Privacy policy: https://primer.systems</li>
</ul>
<p>This is the standard x402 protocol flow. If you prefer to run your own facilitator, you can configure a custom facilitator URL in the plugin settings.</p>
