I'm looking into the daily high-temperature markets and noticed that public weather websites and free APIs usually have a delay of a minute or two. I’ve been tracking a whale who is consistently executing trades under 10 seconds from publication, so there must be a faster feed out there.

Does anyone know of a service, API, or commercial vendor that provides truly real-time, zero-delay temperature data for airport observations? Happy to pay for a subscription if a fast one exists. Any pointers would be hugely appreciated!

I don't expect anyone to reveal their secrets, but maybe you can mention what is and what isn't possible. What are some realistic profit opportunities that don't require going head to head with institutional infrastructure?
