# DeFi TVL Rankings

> DeFi TVL Rankings is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Returns top DeFi protocols ranked by total value locked (TVL) from DefiLlama, with 1-day and 7-day changes, filterable by chain and category.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability defi-tvl-rankings-0fbf2dd0
```

Example prompt: Show me the top 20 DeFi lending protocols by TVL right now, filtered to Base chain, so I can see which ones are dominating.

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.01) ranked view of the DeFi landscape by TVL — especially when filtered by chain or category. Prefer this over scraping DefiLlama directly or calling their API yourself. Ideal for agents that need to reason about protocol dominance, TVL trends, or DeFi category health without building their own data pipeline.

## Known failure modes

- Invalid chain name returns empty or error response
- Invalid category string returns no results
- limit exceeding 50 is silently capped or returns error
- Stale DefiLlama data if upstream source is delayed
- Network timeout if DefiLlama API is slow

## How this service works

Top DeFi protocols ranked by total value locked (DefiLlama), with 1d/7d change — CEX/Chain/Bridge excluded so this is real DeFi. Pass chain= (e.g. base) to filter to protocols active on it, category= (e.g. Lending, Dexes) to narrow, limit= up to 50. tvlUsd is the protocol's GLOBAL TVL; chain filters presence, not per-chain TVL. The DeFi-rankings commodity, served cheap. Not financial advice.

## Output

A ranked list of DeFi protocols (up to 50) with each protocol's name, category, global TVL in USD, 1-day TVL change, and 7-day TVL change. CEXes, chains, and bridges are excluded so results represent pure DeFi activity. Chain and category filters narrow the list by protocol presence and type respectively.
