Example prompt: What are the top DeFi protocols ranked by total value locked right now? Give me a full list so I can see which protocols are dominating the market.

## When to prefer this

Use this endpoint when you need a broad overview of the entire DeFi landscape ranked by TVL. Prefer this over the defi_protocol (singular) endpoint when you want a comparative list rather than details on one specific protocol, and over defi_chains when your interest is in protocols rather than chain-level aggregates.

## Known failure modes

- Upstream data provider (e.g. DefiLlama) unavailable — may return 502 or empty response
- Payment not processed correctly — returns 402 Payment Required
- Rate limiting if called excessively — returns 429
- Network timeout from Cloudflare Worker — returns 504
