## 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-expiry-api-next-quarterly-contracts-9e8c3d18
```

Example prompt: What are the next 4 quarterly expiration dates and roll dates for ES (E-mini S&P 500) futures, including the last trading day and exact UTC end time for each contract?

## When to prefer this

Use this endpoint when you need a forward-looking list of multiple upcoming quarterly contract expirations for a specific CME or Eurex index future, especially when you need the exact UTC and local trading end times and roll dates. Prefer this over the front-month endpoint when planning position rolls, building trading calendars, or backtesting across multiple quarters. Prefer over the annual endpoint when you want a rolling window of upcoming contracts rather than a fixed calendar year.

## Known failure modes

- Invalid or unsupported product code returns an error — only ES, MES, NQ, MNQ, YM, MYM, RTY, M2K, FDAX, FDXM, FESX, FSMI are supported
- Count outside range 1–12 is rejected
- Malformed ISO 8601 datetime in 'at' parameter causes a parsing error
- Payment failure (x402) if USDC payment is not processed correctly
- Rate limiting or server unavailability on the Render-hosted service
