List merchant discovery info

Changed on Oct 6, 2026

Gets x402 merchant discovery information for a given merchant payment address. This endpoint returns all active x402 resources associated with the specified payTo address, allowing clients to discover what payment-gated resources a merchant exposes and their corresponding payment requirements. If no active resources are found for the payTo address, the endpoint returns an empty resources list. The response is paginated, and by default, returns 20 items per page.
