## 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 laevitas-perpetuals-volume-2cef5456
```

Example prompt: Pull the 1h resolution trading volume data for BTC-PERPETUAL on Deribit for the past week — up to 500 data points.

## When to prefer this

Use this endpoint when you need historical or recent trading volume data specifically for perpetual futures contracts. Prefer this over spot or options volume endpoints when the user is asking about perpetuals. Ideal for quantitative analysis, volume trend detection, or building dashboards for crypto derivatives markets. Supports fine-grained filtering by exchange, instrument, and time resolution.

## Known failure modes

- Missing or invalid API key returns 401 unauthorized
- Invalid exchange name returns empty data or 400 error
- Invalid instrument_name returns empty data array
- start/end timestamps in wrong format cause query errors
- limit exceeding 1000 returns validation error
- Unsupported resolution value returns 400 error
- Insufficient x402 payment returns 402 Payment Required

## How this service works

Professional market data API for crypto derivatives, spot markets, prediction markets, Hyperliquid HyperCore data, proprietary volatility surfaces, and analytics.

## Authentication

Use an API key for authenticated REST requests:

```http
X-API-Key: your-api-key-here
```

Most data endpoints also support x402 pay-per-request without an API key.
