x402ads.io Campaign Data Fetcher

Use this endpoint when an AI agent needs to programmatically retrieve ad campaign data from x402ads.io, especially when querying performance over a specific period (7d, 30d, or lifetime). Prefer this over manual dashboard access when automating campaign reporting or monitoring workflows.

• Invalid period enum value returns 400 Bad Request
• Expired or insufficient USDC payment returns payment error
• No campaigns found returns empty result set
• Unauthorized access returns 401
