x402 + ERC-7710

Use this skill when a user wants a payment or subscription demo where an agent pays for HTTP resources through x402 and spends only within a bounded delegated permission.

Core Model

• x402 is the per-request payment rail. A protected resource can respond with HTTP 402 Payment Required, payment requirements, and a retry path where the client submits a signed payment payload. A facilitator can verify and settle the payment before the server returns the resource.
• ERC-7710 is the capability redemption interface. It standardizes how a delegation manager validates permission context and executes delegated actions on behalf of a delegator.
• ERC-7715 is the wallet permission request layer that can be used to obtain scoped permissions for ERC-7710-style delegation.

Use x402 for "pay now for this HTTP request." Use ERC-7710/7715 for "this agent may keep paying under these constraints."

Discovery-First Boundary

When the user has only asked to use or inspect a paid HTTP service, stay in discovery mode:
