## 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 defillama-options-protocol-summary-f73a702e
```

Example prompt: Can you pull the DefiLlama options summary for Lyra, including daily premium volume history but excluding the aggregate chart breakdown?

## When to prefer this

Use this endpoint when you need detailed volume and historical data for a specific DeFi options protocol by its DefiLlama slug, as opposed to broad overviews across all protocols. Prefer this over DEX or fees endpoints when the subject is options markets specifically.

## Known failure modes

- Missing required 'protocol' query parameter returns an error
- Invalid or unknown protocol slug returns empty or error response
- Invalid dataType string may return no data or unexpected results
- Network timeout or upstream DefiLlama API unavailability causes failure
- Payment of $0.005 USDC not fulfilled results in 402 response

## How this service works

Options summary by DefiLlama — volume and history for one options protocol by slug.

## Output

Returns volume and historical chart data for the specified options protocol, including metrics like daily premium volume and daily notional volume, with optional filtering to exclude aggregate or per-protocol chart series.
