## When to prefer this

Choose this endpoint when you need a quick, AI-curated snapshot of the top DeFi protocols without requiring an API key subscription — ideal for agents that prefer pay-per-use micropayment access via x402 on Base. Best suited for on-demand DeFi intelligence rather than continuous streaming data feeds.

## Known failure modes

- Payment not included or insufficient USDC amount — returns 402 Payment Required
- Invalid or malformed x402 payment header — returns 402 with payment details
- Network or chain issues with Base USDC payment processing — payment fails
- Upstream DeFi data source unavailable — may return stale or error response
- Invalid filter properties parameter — may return 400 Bad Request

## 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

A ranked list of top DeFi protocols with AI-generated intelligence, including relevant metrics, rankings, and protocol-level insights to help users understand the current DeFi landscape. Response is returned after a micropayment of $0.005 USDC is processed via x402.
