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 saylor-innovations-data-desk-ethereum-layer-2-rankings-b34c7dbb
```

Example prompt: Pull the top 20 Ethereum Layer 2 rollups ranked by total value secured from L2BEAT, including their 7-day TVS change, stage, category, and stack.

## When to prefer this

Choose this endpoint when you need a broad, ranked snapshot of the Ethereum Layer 2 ecosystem sourced from L2BEAT — including TVS, market share, 7-day momentum, rollup stage maturity, and technical stack. Prefer it over on-chain TVL endpoints when you want pre-aggregated, ranked, human-readable L2 comparisons without having to query individual chain contracts. Best for DeFi dashboards, research, competitive analysis, and monitoring Layer 2 ecosystem health.

## Known failure modes

- Invalid limit parameter (outside 1-50 range) may return an error or default behavior
- Stale data if L2BEAT upstream is temporarily unavailable
- Empty or null fields for projects under review or with incomplete data
- HTTP 402 if x402 payment is not included or payment fails

## How this service works

Ethereum Layer 2 ranking - L2BEAT total value secured, share, 7-day change, stage, category and stack for Base, Arbitrum, Optimism and 90+ rollups

## Output

Returns a JSON object with a list of ranked L2 projects (name, rank, slug, TVS in USD, share percentage, 7-day change percentage, stage, category, stack, host chain, under-review status), plus aggregate stats like total value secured across all rollups, a timestamp for when data was checked, the data source (L2BEAT), and a contextual note. The number of results is controlled by the optional `limit` parameter (default 15, max 50).
