## 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 defi-tvl-by-chain-ranked-96d6a101
```

Example prompt: Show me all the blockchain networks ranked by their total value locked in DeFi right now — I want to see which chains have the most capital locked up.

## When to prefer this

Use this endpoint when you need a comprehensive, ranked snapshot of TVL across all blockchain networks in a single call. Prefer it over chain-specific TVL endpoints when the goal is cross-chain comparison or identifying which ecosystem holds the most DeFi capital. Good for dashboards, research, and competitive analysis across chains.

## Known failure modes

- Upstream data provider outage returns 502 or empty response
- Stale data if the underlying source has not refreshed recently
- Payment of 0.01 USDC not submitted results in 402 Payment Required
- Rate limiting or worker capacity issues return 429 or 503
