## 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 futures-contract-discovery-specifications-b230c563
```

Example prompt: Show me all currently active futures contracts for the ES product — I need the tickers, maturity dates, and tick sizes.

## When to prefer this

Use this endpoint when you need to discover available futures contracts or retrieve contract specifications (tick size, settlement, maturity) for a known or unknown product code. Prefer this over options or stock endpoints when the asset class is specifically futures.

## Known failure modes

- Unknown product_code returns empty results or 404
- Invalid ticker format returns error or empty list
- limit exceeding 1000 is clamped or rejected
- Payment not processed results in 402 response
- Missing required query params may return all contracts up to default limit of 100
