When a paywalled URL is requested without a valid `Payment-Signature` header, the plugin responds with HTTP 402 and a `PAYMENT-REQUIRED` payload describing how to pay. Bots, API clients, and browser-wallet users can sign a USDC transfer, retry the request, and get the response. Use it to: * Charge automated agents per article view. * Offer pay-per-request access to a small set of premium posts. * Test the x402 payment flow on Base Sepolia without setting up your own facilitator. The plugin is inert until you pick a paywall mode in **Settings x402 Pay**. The default mode is «No posts,» so installing the plugin alone does not gate anything or contact any external service. #### Audience and modes * **Audience** decides who gets paywalled. «Only bots» (default) uses crawler detection so human readers still see your content. «Everyone» gates both humans and bots. * **Mode** decides which posts qualify. Choose «No posts» (off), «All posts,» or restrict the paywall to a chosen category. #### Built-in facilitators * **x402.org (Test network)** — routes verify and settle calls through the public x402.org facilitator on Base Sepolia. Default for new installs. No real funds move. * **Coinbase CDP** — routes through Coinbase Developer Platform on Base mainnet( real USDC). Requires a CDP API key. ### External services This plugin connects to external x402 facilitators to verify and settle payments. A facilitator is **only contacted when a request hits a paywalled URL** carrying a `Payment-Signature` header, or when an admin clicks **Test connection** on the settings page. Installing the plugin without selecting a paywall mode triggers no outbound calls. #### x402.org (Test network) Used by the default `x402.org (Test network)` connector. * Endpoint: `https://x402.org/facilitator/` * What is sent: x402 PaymentRequirements (your receiving wallet address, amount, asset, network, resource URL) and the paying client’s PaymentPayload (a signed USDC `transferWithAuthorization` authorization). * Why: to verify and settle the USDC payment on Base Sepolia. * Site: https://www.x402.org/ * Terms of use: https://lfprojects.org/policies/terms-of-use/ * Privacy policy: https://lfprojects.org/policies/privacy-policy/ * This is a public testnet facilitator; do not use it for production paywalls. #### Coinbase Developer Platform Used only when an admin selects the **Coinbase CDP** connector and saves an API key. * Endpoint: `https://api.cdp.coinbase.com/platform/v2/x402/` * What is sent: the same x402 PaymentRequirements and PaymentPayload, plus a CDP- signed JWT proving the API key. * Why: to verify and settle the USDC payment on Base mainnet. * Terms of service: https://coinbase.com/legal/developer-platform/terms-of-service/ * Privacy policy: https://coinbase.com/legal/privacy ### Development Source, build instructions, and issue tracker: https://github.com/Automattic/x402- pay The admin UI is built from `assets/src/index.jsx` via `npm run build`; the bundled` assets/build/index.js` is the compiled output. ## ئېكران كەسمىسى [⌊Choose paywall scope, audience, and price from a single Settings page.⌉⌊Choose paywall scope, audience, and price from a single Settings page.⌉[ Choose paywall scope, audience, and price from a single Settings page.

Install and activate the plugin. 2. Visit **Settings x402 Pay**. 3. Enter the wallet address that should receive payments. 4. Pick a paywall mode and audience. 5. Pick a facilitator. For Coinbase, paste your CDP API Key ID and secret. 6. Save. ## FAQ ### What does a paywalled request look like? If the request does not carry a valid `Payment-Signature` header, the plugin returns HTTP 402 with a `PAYMENT-REQUIRED` response header containing the encoded x402 PaymentRequirements. Clients sign the requirements and retry the request. ### Does this charge human readers? Only if you set Audience to «Everyone.» The default is «Only bots/crawlers» so humans see posts as normal and only detected bot/agent traffic gets a 402. ### Do I need ETH to receive payments? No. x402 uses EIP-3009 `transferWithAuthorization`; the facilitator pays gas. You only need USDC inbound. ### Where are API keys stored? Coinbase CDP secrets are stored in their own `wp_options` row, or can be supplied via a `wp-config.php` constant or environment variable so they stay out of the database entirely. ## باھالاشلار بۇ قىستۇرمىغا تېخى باھا يېزىلمىدى. ## تۆھپىكار ۋە ئىجادكار «x402 Pay» كودى ئوچۇق يۇمشاق دېتال. تۆۋەندىكى كىشىلەر بۇ قىستۇرمىغا تۆھپە قوشقان. تۆھپىكار * [ Steve Dufresne ](https://profiles.wordpress.org/dufresnesteven/) * [ Tellyworth ](https://profiles.wordpress.org/tellyworth/) [«x402 Pay» نى تىلىڭىزغا تەرجىمە قىلىڭ](https://translate.wordpress.org/projects/wp-plugins/x402-pay) ### ئىجادىيەتكە قىزىقامسىز؟ [كودقا كۆز يۈگۈرتۈپ](https://plugins.trac.wordpress.org/browser/x402-pay/)، [SVN خەزىنە](https://plugins.svn.wordpress.org/x402-pay/) تەكشۈرۈپ ياكى [RSS](https://plugins.trac.wordpress.org/log/x402-pay/?limit=100&mode=stop_on_copy&format=rss) ئارقىلىق [ئىجادىيەت خاتىرىسى](https://plugins.trac.wordpress.org/log/x402-pay/)گە مۇشتەرى بولغىلى بولىدۇ. ## ئۆزگىرىش خاتىرىسى #### 0.1.3 * Use canonical coinbase.com legal URLs so the terms and privacy links pass Plugin Directory link validation. #### 0.1.2 * Public 402 page assets now use WordPress enqueue APIs for Plugin Directory review compliance. #### 0.1.1 * Paywall page now swaps the wallet buttons for a single live status message while a payment is in progress, and surfaces wallet rejections or settlement failures in a dismissible modal so visitors can retry. #### 0.1.0 * Initial release: paywall posts by category or all posts; gate humans, bots, or both; verify and settle USDC payments via x402.org on Base Sepolia or Coinbase CDP on Base mainnet. ## Meta * Version **0.1.3** * ئاخىرقى يېڭىلانغان ۋاقىت **3 ھەپتە بۇرۇن** * ئاكتىپ ئورنىتىش سانى **10 دىن ئاز** * WordPress نەشرى ** 7.0 ياكى يۇقىرى ** * **7.0.2** دا سىنالغان * PHP نەشرى ** 8.1 ياكى يۇقىرى ** * تىل * [English (US)](https://wordpress.org/plugins/x402-pay/) * بەلگە * [micropayments](https://ug.wordpress.org/plugins/tags/micropayments/)[paywall](https://ug.wordpress.org/plugins/tags/paywall/) [usdc](https://ug.wordpress.org/plugins/tags/usdc/)[x402](https://ug.wordpress.org/plugins/tags/x402/) * [ئالىي كۆرۈنۈش](https://ug.wordpress.org/plugins/x402-pay/advanced/) ## دەرىجە No reviews have been submitted yet.
