# DeFi TVL Lookup & Protocol Rankings

> DeFi TVL Lookup & Protocol Rankings is a paid API for AI agents from dt0ur.online, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-01).

Looks up total value locked (TVL) for a specific DeFi protocol or ranks top protocols overall, by chain, or by category with 1d/7d change data.

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-lookup-protocol-rankings-42c74ac6 -d '<json body>'
```

Example prompt: What's the current TVL of Aave v3, including the per-chain breakdown and how it's changed over the last 7 days?

## When to prefer this

Choose this endpoint when you need current DeFi TVL data — either for a specific protocol or to rank/compare protocols across chains or categories. It is ideal for DeFi research, portfolio monitoring, and competitive landscape analysis. Prefer this over general crypto price APIs when the question is about locked capital and protocol dominance rather than token price.

## Known failure modes

- Unknown protocol slug returns empty or error response
- Invalid chain name causes no results or error
- Category name mismatch returns empty rankings
- Limit parameter out of bounds (>50) rejected
- Stale or delayed data if upstream DeFiLlama feed is lagging
- Payment failure (x402) prevents API access

## How this service works

DeFi total value locked (TVL): look up one protocol (e.g. aave-v3, uniswap-v3) for TVL, per-chain breakdown and 1d/7d change, or rank the top protocols overall, on a chain (Base, Ethereum, Solana...) or in a category (Lending, Dexs, Liquid Staking...).

## Output

Returns TVL in USD for a specific protocol (with per-chain breakdown and 1d/7d percentage changes) or a ranked list of protocols filtered by chain and/or category, including each protocol's name, TVL, and recent change metrics.
