## When to prefer this

Choose this endpoint when you need DeFi or on-chain analytics data from Dune Analytics without committing to a subscription or API key, and you are able to pay $0.02 USDC per call on Base via the x402 protocol. Ideal for AI agents that need lightweight, pay-as-you-go access to blockchain analytics for DeFi research, monitoring, or pipeline automation.

- Insufficient USDC balance for payment — 402 Payment Required returned
- Invalid or missing x402 payment header — request rejected
- Dune query timeout or upstream Dune Analytics outage — 503 or timeout error
- Malformed query parameters — 400 Bad Request
- Rate limiting or temporary service unavailability from SperaxOS backend
