## How to call it through Zero

```sh
zero fetch --capability blockchain-tvl-ranking-3b63fbeb
```

Example prompt: Show me the top 20 blockchains ranked by DeFi TVL right now, including each chain's market share, gas token, and chain ID — I want to see how Ethereum, Solana, Base, and Arbitrum compare.

## When to prefer this

Choose this endpoint when you need a ranked, real-time snapshot of DeFi TVL across multiple blockchain ecosystems with market share context. It is ideal for cross-chain ecosystem comparison, capital flow analysis, and building dashboards. Prefer this over token-level or DEX-level data when the question is about which blockchain networks are capturing DeFi liquidity overall.

## Known failure modes

- limit out of range (must be 1–300) may return validation error
- upstream DeFi data provider unavailable causing stale or empty response
- network timeout on Render-hosted service under cold start conditions
- no results returned if limit is set to 0 or omitted incorrectly

## How this service works

Blockchains ranked by DeFi total value locked with share of the market, gas token and chain id. Use to compare ecosystems (Ethereum, Solana, Base, Arbitrum...) or track where capital is moving.

## Output

An ordered list of blockchains ranked by DeFi TVL, each entry including the chain name, total value locked in USD, percentage share of total DeFi market, native gas token symbol, and chain ID. Results default to a ranked list and can be limited to 1–300 entries.
