Any api to fetch the expiry dates?

Hi all,

Is there any API to fetch the next expiry dates. The below is text from the api documentation. I want to pass {"symbols": ["BTC-310524"] } , but for that, I would need to know the next expiry dates for the asset.

You can also subscribe to a Options chain, by passing ‘Asset-Expiry’, e.g. {"symbols": ["BTC-310524"] } will subscribe to all BTC Options expirying on 31st May 2024.

Thank you.

hi, historical expiry dates and settlement prices are available here: Trade Bitcoin & Crypto Futures, Options and Perpetual Swaps | Delta Exchange

for future dates - at any time we have the following:
a) daily expiry so you can today, today+1, today+2
b) weekly expiry every Friday
c) monthly expiry every Friday
