## 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`):

Example prompt: Can you pull me a DeFiLlama-style DEX overview — I want to see aggregated trading volume and market metrics across all major decentralized exchanges right now?

## When to prefer this

Choose this endpoint when you need a DeFiLlama-compatible aggregated snapshot of DEX activity across multiple protocols in a single call, especially when building DeFi dashboards, monitoring DEX market conditions, or comparing trading volume across exchanges. Prefer this over chain-specific TVL endpoints when you want trading/volume metrics rather than total value locked.

## Known failure modes

- Upstream DeFiLlama data unavailable — returns error or stale data
- POST body malformed — returns 400 bad request
- Payment not processed (x402 protocol failure) — returns 402 payment required
- Rate limiting — returns 429 too many requests
- Service downtime — returns 500 or timeout
