Frequently Asked Questions
Common questions about x402 Pay
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.
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.

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.
