## 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-chain-volume-16f3eef8
```

Example prompt: Pull the daily options premium volume for Arbitrum from DefiLlama — I want to see the per-protocol breakdown but skip the aggregate chart data.

## When to prefer this

Use this endpoint when you need options-specific volume data scoped to a single blockchain network, especially when you want to see per-protocol breakdowns of premium or notional volume. Prefer this over the general DEX volumes endpoint when the user is asking specifically about options/derivatives protocols rather than spot trading.

## Known failure modes

- Missing required 'chain' query parameter returns a 400 or validation error
- Unrecognized chain slug returns empty data or 404
- Payment not included or insufficient USDC results in 402 Payment Required
- Network timeout or DefiLlama upstream unavailability causes 503
- Invalid dataType string silently returns default data or error

## How this service works

Options volumes for one chain by DefiLlama — options-protocol volume on a single chain.

## Output

Returns options protocol volume statistics for the specified chain, including daily premium volume, daily notional volume, an aggregate time-series chart, and a per-protocol breakdown chart. Optional flags can suppress either chart dataset.
