Retrieve all aircraft flying under Transponder 1255

I have an emergency response use case to map fire fighting aircraft and our customers are looking for us to pull in data from any aircraft flying under the designated firefighting transponder (squawk) 1255.

Even if we cannot get location for all craft under 1255, if we could get tail numbers, we could then retrieve through the typical process. Any ideas if this is possible? Thank you

One can filter the ADS-B Exchange display by squawk.

I think you should be able to use “GET /flights/search/advanced”
with a query argument of something like {= squawk 1255} but I haven’t tested that.
