## 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 httpay-xyz-632233a3 -d '<json body>'
```

Example prompt: Show me all the DeFi protocols on Base ranked by TVL right now, including their 24-hour and 7-day changes and risk tiers — I want to know which ones are growing and which are highest risk.

## When to prefer this

Use this endpoint when you need a comprehensive, real-time comparison of all Base DeFi protocols by TVL in a single call, especially when risk tier classification alongside TVL momentum (24h/7d changes) is needed. Prefer over scraping DefiLlama directly when you need a structured, pay-per-call API with no API key setup.

## Known failure modes

- Payment not provided — returns 402 with x402 and MPP payment instructions
- Rate limit exceeded on demo mode (10 calls/IP/hour without payment)
- DefiLlama upstream data unavailable — may return stale or error response
- Invalid request body format — returns 400 bad request
