MuseFM Playbook — Mega Bundle Skill Pack

Choose this endpoint when you need to acquire a large set of AI agent skills in a single paid call rather than fetching individual skills one at a time. Prefer this over the free Playbook tier when you need the full curated mega-bundle of 12 signed skill definitions. Best suited for agents bootstrapping a new capability library or pipelines that need bulk skill metadata via x402 micropayment on Base.

• Payment failure or insufficient USDC balance — x402 payment not accepted, endpoint returns 402 with payment details
• Invalid or missing payment header — request rejected before bundle is returned
• Server unavailable — VPS host may be unreliable, resulting in connection timeout or 5xx error
• Bundle schema mismatch — response may not match documented skill count or slug format if bundle is updated
• Rate limiting — repeated calls may be throttled by the Exchange Pro service
