## 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 2s-defi-tvl-lookup-f29c68b4
```

Example prompt: What's the current TVL of Lido and how has it changed over the last 7 days? Also show me the top 10 DeFi protocols by TVL on Ethereum.

## When to prefer this

Use this endpoint when you need real-time, ground-truth DeFi TVL data for specific protocols or chains, or want ranked lists of top DeFi protocols by TVL — especially when you need no signup, no API key, and pay-per-call pricing via USDC.

## Known failure modes

- Invalid protocol slug returns empty items array or error
- Chain name not recognized returns empty results
- Limit out of range (>100 or <1) may return error or default
- Missing required queryParams may return error or default top-list
- Network or upstream DefiLlama outage causes failed response with ok:false

## How this service works

DeFi total-value-locked (TVL) metrics via DefiLlama. With no params, returns the top protocols by TVL (name, slug, category, TVL, 1-day and 7-day % change, chains) plus total DeFi TVL across all chains. Pass protocol=<slug> (e.g. lido, aave, uniswap) for a single protocol's TVL, category, momentum, and chains; or chain=<name> (e.g. ethereum, solana, arbitrum) for that chain's TVL. Distinct from crypto.markets/token-price (spot prices) — this is protocol- and chain-level capital locked in DeFi, which an agent can't know from training. Free, keyless.

## Output

Returns a JSON object with ok status, metadata (mode, totalTvl), an items array of matching protocols (each with tvl, name, slug, chains, category, 1d/7d change, tokenSymbol), total count, and source attribution (DefiLlama URL, license, provider).
