Example prompt: Give me an AI-powered summary of recent DeFi liquidation activity across protocols — I want to know which assets and positions are being liquidated and how significant the volume is.

## When to prefer this

Choose this endpoint when you need a quick, AI-synthesized overview of DeFi liquidation activity without setting up API keys or long-term subscriptions — ideal for pay-as-you-go agent workflows that need on-demand DeFi intelligence with USDC micropayments on Base.

## Known failure modes

- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Malformed request body — returns 400 Bad Request
- Upstream on-chain data temporarily unavailable — returns 503 or error in response body
- x402 payment protocol misconfiguration — payment rejected or not processed

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

An AI-generated summary of recent DeFi liquidation events, likely including aggregated liquidation volumes, affected protocols, collateral asset breakdowns, and potentially at-risk positions or notable liquidation events across the DeFi ecosystem.
