Questions about kubient.com
How do I add kubient.com to app-ads.txt?
Add one line for each account kubient.com gives you: "kubient.com, YOUR_ACCOUNT_ID, DIRECT, 4f12311e6ed900a3". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through kubient.com. The account ID must be the seller_id kubient.com lists for you in its sellers.json; kubient.com will give it to you. Put the file at the root of the domain named as your developer website in the App Store and Google Play listings.
Does kubient.com publish a sellers.json?
We found no sellers.json at https://kubient.com/sellers.json when we last looked on 9 October 2026. Lines naming kubient.com cannot be checked against it.
How many apps declare kubient.com in app-ads.txt?
81,776 apps in Stoqlab's data (delisted apps included) declare kubient.com: 1,073 with at least one DIRECT line and 81,751 with at least one RESELLER line, across 9,514 app-ads.txt files. Counts are recomputed daily.
What is the certification authority ID for kubient.com?
100% of the app-ads.txt lines naming kubient.com carry "4f12311e6ed900a3" in the fourth field. The field is optional; the IAB Tech Lab ads.txt 1.1 specification says identifiers in sellers.json supersede it, so a missing or different value does not make a line invalid.
What is the difference between DIRECT and RESELLER?
DIRECT means the publisher owns the account; RESELLER means an intermediary sells the inventory on the publisher's behalf. DIRECT lines should match a PUBLISHER entry in the network's sellers.json, RESELLER lines an INTERMEDIARY entry.
