## 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 vextorium-defi-options-volume-361d74e4 -d '<json body>'
```

Example prompt: What's the current DeFi options trading volume across all protocols — show me the top 10 by 24h volume, including their chain and market share?

## When to prefer this

Use this endpoint when you need a comprehensive, multi-protocol view of DeFi options trading volume with breakdown by chain and time periods (24h/7d/30d). It is ideal over individual protocol APIs when you want market-wide aggregation sourced from DefiLlama. Prefer this over general DeFi TVL endpoints when the specific question is about options trading activity rather than liquidity locked.

## Known failure modes

- Invalid limit parameter (non-integer or negative) may return a validation error
- Upstream DefiLlama data unavailable may result in empty or stale response
- No body or malformed JSON body may cause a 400 error
- Rate limiting or payment failure via x402 may block the request
