详情介绍:
x402 Pay gates selected WordPress posts behind an x402 payment. 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.
- 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.
安装:
- Install and activate the plugin.
- Visit Settings → x402 Pay.
- Enter the wallet address that should receive payments.
- Pick a paywall mode and audience.
- Pick a facilitator. For Coinbase, paste your CDP API Key ID and secret.
- Save.

常见问题:
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.
更新日志:
0.1.3
- Use canonical coinbase.com legal URLs so the terms and privacy links pass Plugin Directory link validation.
- Public 402 page assets now use WordPress enqueue APIs for Plugin Directory review compliance.
- 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.
- 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.
