sellers.json lookup
Enter a seller ID from an app-ads.txt line, a company name or a domain. We search the sellers.json records of the networks named in our catalog's app-ads.txt files and show who holds each account and how many developer sites list it.
What sellers.json tells you
Each ad network publishes sellers.json (IAB Tech Lab): every account it pays out to, with the holder's name, domain and whether it is the publisher itself or an intermediary reselling the space. An app-ads.txt line names an account by its ID; sellers.json says whose it is. We keep only the accounts some catalog app-ads.txt names, refreshed when the files are read, so a network's full list is not here. Records are as the networks declare them; we don't verify them.
