## 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 blockchains-ranked-by-defi-tvl-with-market-share-62ef63de -d '<json body>'
```

Example prompt: Show me the top 50 blockchains ranked by DeFi TVL along with their market share percentages.

## When to prefer this

Use this endpoint when you need a ranked, market-share-aware view of DeFi TVL across multiple blockchains in a single call. It is ideal for competitive chain analysis, protocol deployment decisions, or building dashboards that track DeFi dominance. Prefer this over manual aggregation from chain-specific APIs when you need normalized, comparable TVL data with market share already computed.

## Known failure modes

- Invalid limit value outside 1–200 range returns a validation error
- Payment failure (x402) if the $0.002 USDC fee is not provided
- Upstream data source unavailable may return a 5xx error or stale data
- Empty or malformed request body may cause a 400 bad request
