## 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 agent402-tools-l2-tvl-rankings-a3c54205 -d '<json body>'
```

Example prompt: Can you pull the top 25 Layer 2 blockchains ranked by TVL right now, including their native token symbols and CoinGecko IDs?

## When to prefer this

Use this endpoint when you need a quick ranked snapshot of Layer 2 blockchains by TVL, especially when you also need token metadata (CoinGecko/CMC IDs) for downstream price lookups or analysis. Prefer this over manually querying DeFiLlama when you need L2-specific filtering with classification already applied.

## Known failure modes

- Limit out of range (must be 1-50) returns validation error
- DeFiLlama upstream unavailable causes failed fetch
- Payment of $0.002 USDC not processed results in 402 Payment Required
- Unknown or newly launched L2s may not be classified correctly

## How this service works

Top L2s by Total Value Locked (TVL) via DeFiLlama. Returns each L2 with TVL in USD, native token symbol, and CoinGecko/CMC ids. Classification combines DeFiLlama's parent-chain hint with a curated list of well-known L2s (Arbitrum, Optimism, Base, zkSync Era, Linea, Scroll, Mantle, Polygon zkEVM, Starknet, Blast, Mode, Manta, Metis, Polygon, Taiko, Immutable zkEVM, World Chain).

## Output

A ranked list of up to 50 Layer 2 blockchains, each with TVL in USD, native token symbol, CoinGecko ID, and CoinMarketCap ID — sourced from DeFiLlama and classified using a curated list of known L2s (Arbitrum, Optimism, Base, zkSync Era, Linea, Scroll, etc.)
