ShowMeTheMoney Pro

Execute the protected ShowMeTheMoney premium action only after merchant-backend verification and StablePay payment succeed. This skill is only for the protected premium action exposed by GET /execute?agent_did=<buyer_did>

Main workflow

When the user asks to use the premium ShowMeTheMoney capability:

1. Resolve the current buyer DID from stablepay_runtime_status.
2. Call the merchant backend premium endpoint:

- GET http://127.0.0.1:8787/execute?agent_did=<buyer_did>

1. Treat the merchant backend as the source of truth.
2. If the backend returns 200, return the protected result.
3. If the backend returns 402 Payment Required:

- Parse the x402 response from accepts[0]: - skill_did → from accepts[0].extra.skillDid - price → from accepts[0].maxAmountRequired (convert from minor units to decimal: divide by 1,000,000) - currency → from accepts[0].extra.currency - facilitator_url → from accepts[0].extra.facilitatorUrl - NEVER use any hardcoded or fallback values - call stablepay_pay_via_gateway with the extracted values

1. If payment succeeds, retry the same /execute request once.
2. If the retry still does not return 200, explain that the premium action is still locked or verification failed.

Premium action contract

Use this request for the premium action:

• method: GET
• endpoint: http://127.0.0.1:8787/execute
• required query parameter: agent_did

Optional query parameters may be used when helpful:

• q
• prompt

These optional values are forwarded to the backend as request text for the premium action. The backend should:

1. receive the premium request
2. verify purchase state via StablePay
3. return 402 when the user has not purchased the skill
4. return 200 only after verification succeeds
5. return a merchant-generated proof token in the premium result

Treat the backend response as the final authority.

Unlocked Store (Report Store)

After successful skill purchase, the backend returns unlocked_store in the 200 response. Present the unlocked store information to the user and offer to browse/purchase individual research reports. Each report requires separate payment using the same x402 payment flow.

Payment rules

When payment is required:

1. Use stablepay_pay_via_gateway.
2. Use the requirement returned by the backend when present.
3. Respect local payment limits already configured in the StablePay plugin.
4. Never claim payment succeeded unless StablePay returns a successful result.
5. Retry the premium action only once after a successful payment.
