Brand strategy	3C / SWOT / STP / Porter / 4P / AIPL diagnosis, positioning, brand architecture
Restaurant operations	Store P&L diagnosis, menu engineering, site selection with payback modelling, new-store launch playbooks
Marketing campaigns	Full campaign generation from minimal input, ROI preview, SOPs and rollout calendars
Crisis PR	Food-safety incident response, brand-reputation repair, social-media escalation playbooks
Long-tail (885)	Focused single-purpose kits — budget allocation, A/B test analysis, JD writing, pricing, SOPs, and more

Payment (x402)

Unpaid calls return HTTP 402 with an x402 challenge in the PAYMENT-REQUIRED header. Any x402 v1/v2 client handles this automatically:

1. Client calls the endpoint.
2. Server responds 402 + challenge (amount: 10000 = 0.01 USDC, network: eip155:8453, USDC on Base).
3. Client signs an EIP-3009 authorization and retries with PAYMENT-SIGNATURE (v2) or X-PAYMENT (v1).
4. Server verifies + settles with the facilitator and returns the result, with a receipt in PAYMENT-RESPONSE.

• Both protocol generations are supported — v2 clients and older v1 clients both pay successfully.
• Settlement address: 0x93215E03d66B49bA03c015B4f7c103dD102E39A7
• Facilitator: https://facilitator.xpay.sh
• No API keys, no subscriptions, no accounts.

Free tier

Send X-Expert-Tier: free (or set metadata.tier = "free") to receive the methodology brief for any skill — the frameworks, decision rules and example prompts — at zero cost. The brief costs the publisher nothing because no model is executed. Paid tier returns the finished deliverable.
