## 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-hugen-tokyo-e32ec2d2
```

Example prompt: Give me the full directory of DeFi protocols — I want to see all 5,000+ with their TVL rankings, which chains they're deployed on, and how they're categorized (lending, DEX, liquid staking, yield, etc.).

## When to prefer this

Use this endpoint when you need a comprehensive, authoritative snapshot of the entire DeFi protocol landscape — all 5,000+ protocols with TVL, categories, and chain data in one call. Prefer this over per-protocol lookups when you need to browse, filter, or rank across the full DeFi ecosystem. The sibling protocol-detail endpoint is better for deep data on a single protocol.

## Known failure modes

- Payment not provided or invalid — 402 Payment Required
