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:

1. Identify the relevant endpoint or resource.
2. Confirm whether it returns 402 Payment Required.
3. Summarize the advertised x402 requirements: network, token, amount, payee, route, and extra.assetTransferMethod when present.
4. State that no paid request has been made.
5. Ask whether the user wants to set up bounded payment authority.

Do not draft a subscription, mandate, cadence, schedule, spend cap, expiration, or wallet permission until the user asks for setup or confirms they want to continue. Do not infer "daily", "weekly", or "recurring" authority from a product objective alone; wait for the user to approve delegation design.

Good discovery response shape:

I found the paid endpoint and its x402 requirements.

- Endpoint: GET /path
- Network: ...
- Token: ...
- Price: ...
- Payee: ...

I have not made a paid request. Do you want me to help set up bounded payment authority for this task?
